Cardarine (GW-501516) SARM – Uses, Side Effects, and More

Cardarine (GW-501516) is one of the more popular SARM-like substances that is especially appealing to those wanting a serious performance boost, with this compound showing great ability to enhance endurance. This can open doors to results in multiple areas, from improved athletic performance to fat burning and muscle growth, by taking advantage of your ability to push harder.

So, do you think Cardarine is just another SARM? A lot of people believe that. After all, it’s talked about alongside all the other SARMs. But Cardarine is a little bit different. When it comes to controversial PEDs, Cardarine has to be near the top of the list. It works exceptionally well when used to support anabolic steroids, making it an excellent addition to a steroid cycle thanks to the way Cardarine can reduce or even prevent some of the most worrying side effects many steroids introduce concerning cardiovascular health.

Cardarine is also one of the compounds that split opinions straight down the middle. Some people rave about GW-501516 and think it’s one of the best performance enhancers available. In contrast, others swear they won’t touch it because of the scary scientific literature. Of all PEDs, this is one I hesitated the most about using. Undoubtedly, it comes with significant benefits, and anyone using it usually finds it an incredible PED. So, is Cardarine something you consider using, and what can it do? What are the most significant risks, and are there other options available? Keep reading to learn more about Cardarine. Let’s dive in!

Medical disclaimer: The following guide is based on personal experience and does NOT promote the illegal use of steroids (PEDs). Consult a healthcare professional before using PEDs.

What is Cardarine?

GW-501516 (Cardarine) is in a category of its own when it comes to PEDs, although it’s often thought of and used alongside SARMs. Cardarine is not technically a SARM. Specifically, it is a PPAR receptor agonist that was initially developed in the 1990s as a potential treatment for various cardiovascular and metabolic diseases like diabetes, dyslipidemia, and obesity.

Cardarine also goes by the name Endurobol, or its original chemical research name GW-501516. All of these names refer to the same compound, which has excellent benefits when used alone but also some surprising and welcome benefits when combined with certain anabolic steroids.

Cardarine is particularly popular with runners and other high-intensity athletes. This can be purely for athletic purposes (breaking personal records, for example) or combined calorie-burning and fat-loss goals. Some bodybuilders also appreciate Cardarine’s ability to maintain muscle mass and promote fat loss on cutting cycles.

Cardarine is well known for its ability to promote improved endurance and more efficient fat-burning. Still, early studies showed other benefits, like reducing cholesterol, preventing oxidative stress on the blood vessels, reducing kidney inflammation, and potentially other anti-inflammatory properties. Unfortunately, the cessation of research on Cardarine prevented any more specific findings in these areas, but early results looked promising.

Whether you’re a steroid user or not, though, Cardarine offers multiple benefits, and this is what has made it such a popular compound, despite the fact it’s not always one of the easiest to find and purchase in pure form. The uptake of Cardarine by athletes got the attention of WADA (World Anti-Doping Agency), and in 2009, it was added to the list of prohibited substances.

A Quick Look at Cardarine

• Other Names: GW-501516 (generic), Cardarine, others.
• Primary Use: Investigational compound for metabolic disorders. Off-label use for fat loss, endurance enhancement, and muscle preservation.
• Administration: Oral form (liquid, capsules, or tablets, sold as “research chemicals”). Typical Dosage: 10-20 mg/day (once daily). Half-life: ~16-24 hours (once-daily dosing).
• Cycle Length: 8-12 weeks (commonly stacked with SARMs like Ostarine or RAD-140).
• Benefits: Accelerated fat loss (targets stubborn fat stores); dramatic improvements in endurance and workout capacity; muscle preservation during calorie deficits; no hormonal suppression (safe for natural athletes).
• Side Effects: Potential carcinogenicity (rodent studies showed cancer risk at high doses; human data lacking); insulin resistance (long-term use may impair glucose regulation); mild headaches or nausea (rare); long-term organ toxicity (liver, heart) due to lack of human studies.

Note: Cardarine is controversial due to rodent studies linking it to cancer, though human risks remain unproven. While praised for fat loss and endurance, its long-term safety is unknown, and it is not recommended for use. Prioritize diet, cardio, and natural supplements for similar goals. If used, limit cycles, avoid high doses, and monitor bloodwork (fasting glucose, liver enzymes).

History and Overview

Cardarine was showing so much promise as a possible medical treatment that it was being researched by one of the world’s biggest pharmaceutical companies, GlaxoSmithKline (GSK), in the 1990s (alongside a smaller company called Ligand Pharmaceuticals). However, after an alarming cancer result in animal studies in 2007, GSK swiftly ended its research on this chemical. Even though there was no way of knowing whether these cancer results would have posed a risk to humans, no pharmaceutical company wants to be involved in even a slightly risky product like this… So, that left Cardarine as a discontinued chemical that would never yield investment from a major company again.

A biologist in the US took on some Cardarine experimentation himself and found it to benefit the physical performance of mice. And that is how we came to see Cardarine as a very effective performance-enhancing compound – even though this had nothing to do with the original research goals of GW501516.

Mechanism of Action

Cardarine is a PPAR receptor agonist, so it works differently from the SARMs you might be familiar with. In short, this receptor (PPAR) plays a critical role in processes that are thought to be connected with a whole range of diseases:

• Obesity
• Diabetes
• Atherosclerosis
• Cancer

Testing on rodents showed that when Cardarine binds to the PPAR receptor, it changes processes involved in how energy is expended, increases metabolism of fatty acids in the muscle, protects against type 2 diabetes, and protects against obesity caused by diet. So, while we won’t ever know if these events could have been replicated in human trials (because official research has been discontinued), it doesn’t take much imagination to see why Cardarine has got the attention of the performance and bodybuilding community, especially when it comes to fat loss and athletic performance goals.

Effects of Cardarine (Benefits)

Cardarine’s main desirable benefits (for athletes and bodybuilders) revolve around fat loss and endurance. These are the primary reasons that most athletes and bodybuilders will consider running a Cardarine cycle. Let’s look at the top effects and benefits of Cardarine as it relates to performance use:

Fat loss and muscle preservation

Cardarine’s ability to speed up fat loss is one of the two big reasons anyone wants to use this PED. Although the mechanisms are complex and include reducing insulin sensitivity and boosting insulin resistance, Cardarine can make your body more efficient at using stored body fat as an energy source. This has the dual benefit of preventing catabolic muscle breakdown, as muscle won’t be used as energy and lost forever.

My favorite thing about Cardarine’s fat loss effects is that it can burn both subcutaneous and visceral fat. Visceral fat is responsible for many unwanted abdominal and waist bulges, usually two of the most challenging areas to get lean.

And get this:

Animal studies also found that Cardarine can effectively reverse the metabolic issues resulting in diet-induced obesity. This makes Cardarine a PED valid for hardcore cutting cycles if you’re already lean and for anyone carrying extra pounds and needing a fat loss aid. You still need to exercise regularly and intensively while using Cardarine to achieve body fat loss. The results aren’t as drastic as with something like Clenbuterol, but I’ve seen and experienced enough fat-burning results with Cardarine to know that it holds its own as a PED to include in a cutting cycle.

Muscular endurance

A leading reason why Cardarine is still so popular with athletes is its potent effects on stamina and endurance. You can train at a higher intensity and much longer within the first few days of starting a Cardarine cycle. Cardarine has been found to have a powerful effect on muscle fibers, and this action contributes significantly to its endurance-enhancing effects: By converting fast-twitch muscle fibers into short-twitch fibers, Cardarine reduces muscular fatigue during intensive exercise^[1]. This is what makes Cardarine very popular in the running community! But any intensive cardio activity can benefit. Naturally, with this increased capacity to exercise at a higher level of intensity, you will burn more calories and body fat.

Muscle gains

Cardarine isn’t a PED that will be at the top of your list for bulking, but past studies have shown that it CAN contribute a small amount of lean mass growth^[2]. This essentially means Cardarine can simultaneously promote fat loss and muscle growth. Lean gains won’t be pronounced in men requiring a more potent anabolic. But women can gain a lot of lean mass with the proper diet on a Cardarine cycle.

Cholesterol support

Cardarine can improve your HDL (good) cholesterol levels while reducing LDL (bad) cholesterol. I know some cases where people will include it in a cycle purely for this effect only to offset the adverse cholesterol effects of some SARMs or steroids. While I’d still strongly recommend monitoring cholesterol levels in those cases through bloodwork and not relying solely on Cardarine for support, this benefit can only be seen as a positive no matter what type of cycle you plan to use Cardarine for.

No testosterone suppression

While it’s not a direct benefit, the lack of suppression with Cardarine is very appealing to men. Rarely can we use any PED without at least some risk of suppression and having to do PCT. You can do a whole Cardarine cycle with no concern about low testosterone and no post-cycle therapy!

Cardarine Dosing and Administration

I’ve already talked about how Cardarine is a controversial PED. There’s nothing wrong with not wanting to use Cardarine at all, but those who do will almost always (wisely) say that by keeping the dosage moderate and the cycle length short, we’re reducing our risk to as low as possible regarding those cancer fears. We still don’t know if there’s ANY risk in humans, let alone at doses significantly below what was used in animal testing.

You’ll hear much about dosing Cardarine: There’s no noticeable difference between taking 10 and 20mg daily. This doesn’t mean it will be YOUR own experience, but I found it to be the case, and so do many others. I will say this: If you can get excellent results from 10mg, then stick with that. We still do not know the future health risks associated with taking higher doses of Cardarine.

Doses

The most talked about Cardarine studies were those done on rodents, where cancer development marked the end of this research chemical. But it’s worth noting: The dosages given to the rodents that induced cancer growth were an order of magnitude higher (on a body weight basis) than we humans would ever take. Regarding human clinical trials, Cardarine was only studied a few times, where it was considered well tolerated at doses between 2.5mg and 10mg.

Generally, bodybuilding doses are typically within the 10-20mg daily range. Most of us like to play it safe (considering that cancer word in the back of our minds) and not go wild on the dosage. Cardarine works amazingly well at these doses, so there’s rarely a good reason to take it much higher, regardless of your experience level. Below, I’ve provided a simple guide to dosing for beginner to advanced users, as well as female Cardarine users:

Beginner

New to Cardarine? You can’t go wrong on 10mg daily for eight weeks. Some users won’t ever even exceed this dose. You’ll also know how well you tolerate Cardarine if you’re prepared to take a higher dose in your next cycle.

Make no mistake: 10mg per day of Cardarine will provide an exceptional performance boost. Many users won’t even need to exceed that dose. New users will want to evaluate the effects of 10mg, and if all goes well, the dosage can be increased to 15mg during the same cycle.

Intermediate

15mg is an intermediate dose and should improve cardiovascular endurance and potentially increase fat loss. An 8-10 week cycle is ideal for optimal results if you use Cardarine as the sold compound.

Advanced

Most advanced users will look at stacking Cardarine rather than raising the dosage above 20mg/day. I always say there’s little point in taking more than 20mg of Cardarine – it becomes a case of diminishing returns, AND we don’t know all the possible risks. See below for my suggestions on the best Cardarine stacks!

Female

Cardarine is particularly suited for female users because it lacks hormonal activity. A 10-20mg/day dosage range is suitable for women. No virilization risk exists for women who use Cardarine, but that doesn’t mean taking an excessive dose (females also need to consider the other possible risks involved with Cardarine).

Bioavailability, half-life, and cycle length

Cardarine has a half-life of anywhere between 12 and 24 hours. The exact half-life will always vary between you, me, and everyone else. Why? Metabolism and other factors play a role in the precise elimination of half-life. Still, a once-daily administration is all you will need to maintain a peak level of Cardarine.

One question I often see is, what time of day is best to take Cardarine? Also, should you take it on an empty stomach or with/after food? First, it’s not thought that food or lack of it will alter the bioavailability or absorption of Cardarine. So, taking it on a full or empty stomach shouldn’t make a difference. The most common strategy is to take your daily Cardarine dose 15-30 minutes before training.

Let me say this: Whichever time you find is best for taking Cardarine, make it consistent! Take it at the same time every day so you don’t experience a drop in levels.

How long should your Cardarine cycle be?

As a priority, we limit the use of this PED to the shortest cycle possible (because of that cancer issue again). Luckily, Cardarine works fast, so you don’t waste time waiting for it to kick in at the start of the cycle. A typical Cardarine cycle will be eight weeks long. Shorter cycles of 4-6 weeks are also standard. Some people will run it for up to 12 weeks if you don’t mind the unknown risks.

Dosing schedule and administration methods

Cardarine can be taken once daily; it’s generally best to take it in the morning or before training. Administration is typically done orally with a liquid solution. Some suppliers also sell Cardarine in powder and capsule forms (10mg tablets, for example). I always like to use liquid for maximum bioavailability and the ease of measuring out an accurate dosage.

Morning administration always works well, but some people swear by taking their daily dose briefly (about 15 minutes) before training or running. Experimenting with different times of day for your dose will yield the best results for your schedule but aim to take it at the same time each day whenever possible.

Cardarine Cycles

With Cardarine being equally beneficial for people of all genders, this is one PED where cycles and doses can be very similar (or even the same) for both sexes. Where things will diverge more considerably is once you start to stack Cardarine with other PEDs – more on that in the next section.

The standard safe and effective cycle length for Cardarine is between 8 and 12 weeks. How long you use Cardarine will significantly depend on whether you rely on it as a primary compound or use it alongside a steroid like Trenbolone as a supportive compound, mainly to mitigate the cardiovascular-related side effects.

The short half-life of Cardarine, lasting anywhere from 12 to 24 hours, makes it best to break your daily dose into a twice-daily administration to maintain the most optimal blood levels. Many will take Cardarine two to three hours before a workout to maximize its endurance-related benefits.

Cardarine cycle for men

A standard 8- to 12-week Cardarine cycle at 15mg-20mg will provide excellent fat loss and body composition results. Endurance will be noticeably improved, starting within just the first few days. Expect to be able to run/swim/cycle at a much higher intensity and for longer.

Yes, this impressive boost to endurance and performance will mostly subside once you stop a Cardarine cycle; in other words, you’re not likely to be able to work out at the same level once Cardarine leaves your system.

However:

I and many other users have found that at least SOME of this improved endurance is retained. But you’ll need to keep up that same level of exercise to see the ongoing improvement (keeping in mind that the heart is a muscle). This is the lowdown of results that male Cardarine users experience: A noticeable improvement in endurance, which starts very quickly.

Some of the most positive comments inevitably discuss how fast Cardarine starts working. There is no need to start waiting weeks for the effects to kick in. Thanks to its short half-life, virtually all Cardarine users start noticing improvements within the first two days.

Increased vascularity is something you’ll read a lot of guys raving about as well. Expect some notable vein popping within two weeks; just how much of it can be attributed to the massive increase in exercise intensity vs. becoming leaner will depend on you as an individual – but everyone loves looking more vascular! Even with a mild calorie deficit diet, guys note fat loss results of up to 10 lbs in the first three weeks.

Some negative reviews or comments about Cardarine include headaches, but this is likely only in susceptible individuals. It’s to be expected that a lot of the negative commentary about Cardarine – including those who’ve never used it – tends to focus on the cancer risks I’ve talked about here.

Cardarine cycle for women

Women can use Cardarine virtually identically to how men use it, as there are no hormonal effects to be concerned about. That means no virilization side effects for females! Still, doses should be kept moderate to minimize other potential side effects. 10-15mg daily is sufficient for women with exceptional body recomposition results. A cycle of 8 weeks in length is adequate for most females. If you prefer a longer cycle, it’s recommended not to extend past 12 weeks maximum.

First-time female users will often start at 10mg to evaluate the response and effects. Women who want more pronounced effects can also use the same higher doses as men, with 20mg often considered optimal. Women can make significant gains in lean mass on a Cardarine cycle. Naturally, your diet and training regime are going to contribute to your outcomes here, but you can expect results such as:

• Simultaneous loss of fat and muscle growth
• Existing muscle will be preserved if you’re using Cardarine for cutting
• Endurance will be boosted – longer, more intense workouts
• Positive changes to cholesterol (increased HDL)

Female runners who use Cardarine note that, similarly to men, the endurance and stamina changes come on quickly and are significant. Cardiovascular exercise is said to feel easier to do at a much higher intensity than usual. Regarding body fat loss, expect anywhere from 5% to 15% body fat reduction (depending greatly on your current weight plus your diet). Once the fat drops off, females note an exceptional improvement in muscular definition (especially around the abdominals).

Few females have negative experiences with Cardarine simply because it’s so side-effect-friendly. The only negative will be those women wanting more hardcore results – in which case they can use something like Anavar instead or a more potent fat burner like Clenbuterol.

Cardarine-only cycle

Cardarine is still useful when used alone in a cycle, and for beginners, this can be the ideal option to get a good idea of what this compound does for you. Dosed anywhere from 10 to 20mg daily, you will see significant improvements in stamina, endurance, and more efficient fat loss.

The cycle should run for 8 to 10 weeks; you can expect no side effects. New users will benefit from starting the cycle at 10mg per day, dosing twice daily, and increasing this to 15mg two to three weeks into the cycle. If more significant effects are desired, a maximum of 20mg per day can be safely taken. Still, there is no real benefit to increasing the dose past that level, regardless of your experience level. If you want more powerful benefits, then your next cycle should be a stack so you can complement Cardarine with other compounds.

Cardarine bulking cycle

Cardarine is not among the first compounds people use in a bulking cycle since its main benefits are fat loss and endurance enhancement. But improving performance is still of great benefit for those doing a bulking cycle, as the more and heavier you can lift, the quicker your gains will come on.

Those wanting to give Cardarine a go in a bulking cycle will likely be stacking it with a powerful bulking steroid like Nandrolone (Deca-Durabolin). Cardarine can serve multiple benefits here: To enhance cardiovascular strength and help power your workout endurance while offsetting some of the cholesterol impacts Deca is well known for.

Depending on your steroid experience, using Deca at anywhere from 300mg to 600mg weekly combined with 10-20mg daily of Cardarine is going to result in a powerful bulking result with a 10-week cycle. PCT will be required due to Deca’s extreme testosterone suppression activity.

Cardarine cutting cycle

A great SARM to stack with Cardarine for cutting or fat loss purposes is RAD140 (Testolone), which gives a significant strength boost. 20mg of Cardarine and 10mg of Testolone daily for an 8-week cycle will make for impressive fat loss and toning. This stack may require PCT following the cycle due to the addition of Testolone.

Advanced users who want a more significant boost to stamina during this cycle may consider adding Stenabolic at 20mg daily, administered twice daily, as that compound has a short half-life of 5 hours or less. The increased endurance, stamina, and strength in this cycle will significantly boost your performance, encouraging faster fat loss directly through Cardarine’s impact on energy and calorie use and indirectly as you can work out more intensively for longer.

Beginner Cardarine cycle

If you’re a first-time user of Cardarine, then a good place to start is at 10mg per day. You’ll be introduced to Cardarine at this low dose and can quickly evaluate your response (endurance benefits should come within the first day or two). Adjust your dose if desired. Because Cardarine starts working immediately, you can do a cycle as short as four weeks and see substantial results. If your main goal is fat loss, you will need a longer cycle, but if performance is your top priority, then four weeks provides an excellent introduction to Cardarine. A 10mg per day cycle for 4-6 weeks is the ideal beginner Cardarine cycle.

Intermediate Cardarine cycle

Once you’ve used Cardarine once or twice for an entire cycle and enjoyed your results, you might consider increasing the dosage. Cardarine’s effects on endurance are excellent, even at 10-15mg, so it’s important not to expect a doubling of the impact if you double your dose from 10mg to 20mg for this cycle.

Intermediate users will rarely want to exceed 20mg, and there’s little benefit in doing so. If you require more powerful effects, especially for fat loss, this is the time to consider adding one other compound to your cycle. In this case, you would only need 10mg of Cardarine, while 15mg of Ostarine will make this a potent fat-burning and muscle maintenance 8-week cycle.

Advanced Cardarine cycle

Most advanced Cardarine users will be at the stage where stacking it with other potent compounds will be the only option to take performance and results to another level. Since increasing Cardarine’s dosage beyond 20mg or 25mg holds no notable benefits but only potential downsides, stacks like the examples noted below are the best option for all advanced users.

Very few advanced or experienced users will choose to use Cardarine on its own but rather take advantage of some of its unique effects to complement SARMs and steroids. In these stacking cycles, advanced users will almost always use a lower dose of Cardarine in the 10-15mg range.

My source for Cardarine

Endurance and fat burning are the two reasons people will use Cardarine and do so while putting the potential risk of cancer development to the back of the mind. I like to remove that risk altogether, so I turned to the best Cardarine alternative: C-Dine 501516.

Like Cardarine, C-Dine excels at boosting your endurance and optimizing fat loss. Ensure you’re on a well-planned calorie-deficit diet for maximum fat burning. While Cardarine’s fat loss results are impressive enough, C-Dine is even more effective at burning your stored fat, and with its effects on decreasing your appetite, I find it much easier to stick with my planned diet on C-Dine 501516.

Why I Like It: C-Dine reduces my appetite, so I’m no longer craving calories I don’t need, which speeds up fat loss to the maximum potential.

It’s Worth Noting: C-Dine is not a weight loss magic pill, so if you’re eating excess calories or low-quality food, your results might not be what you expected.

The stamina and endurance effects of Cardarine are legendary, and even if you’re not primarily aiming for a lot of fat loss, C-Dine holds significant benefits for athletes in terms of performance. Cardio performance with C-Dine is on par with Cardarine: If you struggled to run 3 miles before, it’s realistic to expect to be able to run twice that distance or more and have it feel like you could go even further. Whether for fat burning or increased exercise capacity and performance, C-Dine’s side-effect-free formula has been carefully put together into a once-daily pill that can be safely used for three months or longer with no adverse effects. If you decide to use C-Dine, I recommend buying it here.

Cardarine vs. Other PEDs

It’s always a good idea to keep an open mind and consider all your options, especially when you’re new to this. Haven’t tried all or any other PEDs yet? Then, without that personal experience, you won’t know whether a different SARM, steroid, or other compound could be a better option for YOUR goals than Cardarine is – no matter how much you’ve read about other people’s experiences.

Cardarine is not a SARM or a steroid; it sits in a separate class of drugs. Despite this, it is still often considered a SARM and used similarly. SARMs and other compounds like Cardarine do not have similarities to steroids besides their performance benefits, with the advantage that they often come with little to no side effects.

Compared with anabolic steroids that usually come with severe side effects, Cardarine is much more mild and well tolerated but still delivers excellent performance and physique-building benefits. The best way of using Cardarine for ultimate results is to take advantage of the way it works as a fantastic support compound in a cycle that also includes either SARMs or anabolic steroids.

Cardarine will contribute significantly to these cycles by promoting fat brining and reducing bad cholesterol (LDL) levels and triglycerides, offsetting some severe cholesterol impacts that steroids can cause. This supportive use of Cardarine only requires low doses, which is still very efficient at maintaining healthy lipids – a must-do when using steroids.

Other SARMs will have varying effects that sometimes overlap with Cardarine’s, while others are entirely different. For example, Ostarine is another excellent fat loss and muscle preservation cycle, while Testolone is powerful for mass building. The wide variety of SARMs makes it appealing to stack two or more together with Cardarine to achieve a more specific result.

The list of PEDs I could try to compare to Cardarine is long, but I’ve chosen three of the closest and most usable other PEDs you might consider if Cardarine is on the table for you. Anavar, Ostarine, and Stenabolic are worth looking at very closely to compare the good and bad of each one alongside Cardarine.

Cardarine vs. Anavar

If there’s one anabolic steroid to compare Cardarine with, it’s Anavar. This very “female-friendly” steroid is one of the milder AAS in terms of side effects, but it’s still a steroid, so it works very differently from Cardarine.

Anavar can help you put on some solid lean mass if you’re female. Cardarine won’t have that sort of muscle-building effect. Most men find Anavar not strong enough to use, particularly for muscle growth. Anavar will be far more powerful compared to Cardarine in certain areas (especially for females), like:

• Strength
• Muscle gains
• Fat loss

Cardarine will improve endurance at a higher level (for most users) than Anavar can. Some people find that Anavar worsens cardiovascular performance. And side effects? Females are at risk of virilization when using Anavar. Not so with Cardarine. And because Cardarine is not a suppressing compound, men don’t have to bother with PCT.

There’s no right or wrong decision here: When choosing between Cardarine or Anavar, you need to have a perfect idea of what specific goals and effects you’re trying to achieve.

Cardarine vs. Ostarine

A Cardarine and Ostarine stack is what you might call the perfect stack (see my thoughts on that in the next section). But what if you want to compare these two PEDs with the view of using one on its own in a cycle? Both are considered excellent fat loss PEDs, although both Ostarine and Cardarine work more indirectly to achieve body fat loss!

Ostarine can boost the metabolic rate while preserving lean muscle. Cardarine mainly helps you achieve fat loss through increased stamina and endurance (more intensive exercise = faster fat burning). As a pure fat loss cycle, there are better options than either. However, both will deliver results for a performance cycle, with fat loss being just one goal. If I had to choose one as a sole compound, it’d be Cardarine. It’s just the more potent performance enhancer.

But you know what? I would instead stack Cardarine and Ostarine and do a proper cycle, allowing Ostarine to protect lean muscle while Cardarine does its thing.

Cardarine vs. SR-9009

Stenabolic (SR-9009) is the most obvious PED to compare to Cardarine because they are so similar in their effects.

Like Cardarine, Stenabolic is also not a SARM (a REV-ERBa agonist). Still, both are exceptionally good at boosting cardiovascular performance, improving cholesterol, and promoting body fat loss. Although they achieve this in different ways, for you as the athlete, both these PEDs will boost endurance and stamina, among other substantial benefits.

So, if your choice comes down to using either Stenabolic or Cardarine, which do you choose? Stenabolic is a first choice if the cancer concerns of Cardarine are a big worry for you. However, Stenabolic does have a downside regarding administration: SR-9009 has low bioavailability and a short half-life that requires it to be taken 2-4 times daily. Compare that to Cardarine’s convenient once-per-day dosage, and it’s clear which is the easier compound to take.

The good news is that the immediate side effects of both Cardarine and Stenabolic are minimal. As a newbie, I’d recommend Cardarine at a low dose simply because it’s less hassle than Stenabolic. However, the results will be similar, and ultimately, the only way to know which one you respond to the best is to run separate cycles with both.

Stacking Cardarine

Cardarine is quite effective, but you will always want to stack it with at least one other PED for higher-level results (cutting, muscle gains, or performance). As I mentioned, this is far more ideal than raising your Cardarine dose. Below are some suggested stacks you can try with Cardarine:

Cutting and endurance stacks

Cardarine can be used in any cutting cycle, with even a low dose of 10mg vastly adding to your capacity to boost endurance and cardiovascular performance and burn fat. A nice bonus is its protection of cholesterol levels, which can offset the adverse cholesterol effects of some other PEDs.

Cardarine + Ostarine

One of the most straightforward (yet powerful) cutting or fat loss stacks you can do is Cardarine and Ostarine. Men doing this stack will mainly focus on fat burning, as minimal muscle can be gained. But females will be more reactive to the anabolic effects of Ostarine, with impressive lean gains possible if your diet supports it. The real value of this stack is in the simultaneous fat burning and muscle growth and preservation, resulting in awe-inspiring results in body recomposition.

Benefits:

• Significant body fat loss – 8% or more
• High level of muscle retention on a cutting diet
• Increased muscular endurance
• Energy and strength are maintained while on a calorie-deficit diet

Dosing:

• Ostarine: 20mg/day for eight weeks
• Cardarine: 10mg/day for eight weeks

Possible side effects:

Ostarine does come with some side effects to watch out for, including reducing HDL cholesterol levels, some liver toxicity, and testosterone suppression. Both of these PEDs can elevate your liver enzymes. Headaches caused by Ostarine are commonly reported side effects at the beginning of the cycle.

Results:

Just how much fat you could lose on this stack will depend on:

• Your current weight and body composition
• Your training regime
• The quality and quantity of your calorie intake

It’s entirely doable to shed up to 10% of body fat. Men are not likely to gain much or any muscle at all. Still, the existing muscle will be preserved well, becoming more noticeable as fat reduces – increased muscular definition with losing the fat that was previously hiding your muscle tone. Women can see significant muscle gains, with 10-20lbs more than possible if you’re not on a calorie deficit diet. At the same time, fat loss is taking place, resulting in impressive improvements to overall body composition.

PCT

Countless times, I’ve heard and read guys saying Ostarine doesn’t suppress. Well, it can, and it does! Sticking to my recommended dosage above (or reducing it) will minimize suppression, but you should still prepare for PCT, just in case. A simple Nolvadex or Clomid PCT at 20mg/day for four weeks will do the trick. Can you get by without PCT? Some guys definitely can, but getting bloodwork done is the only surefire way of knowing what’s happening with your testosterone. Naturally, women don’t require PCT with this or any other cycle.

Cardarine + Stenabolic

This stack is a performance powerhouse. Stenabolic and Cardarine have powerful effects on endurance and stamina; you won’t find a more impressive combination. With significantly boosted performance capabilities, you can burn remarkable amounts of fat if that’s your goal.

Benefits:

• Massive stamina and endurance boost, increased intensity, and length of workouts.
• Faster and more efficient fat-burning.
• Preserve muscle mass while dieting and doing intensive cardio exercise.
• Fast acting.

Dosing:

• 15mg/day Stenabolic
• 15mg/day Cardarine
• Cycle length: 8 weeks

Possible side effects:

• Cancer risks of Cardarine
• Insomnia (rare side effect of Stenabolic)
• Some liver stress

Both compounds will boost your endurance and cardio performance to a very high level. This is a perfect fat loss and performance enhancement stack with minimal side effects. The downside is the need to administer Stenabolic 2-4 times daily because of its short half-life. PCT is not required after this cycle since neither Cardarine nor Stenabolic are suppressive.

Cardarine + RAD-140

This can be either a bulking or cutting stack. Low doses of each PED here will still give excellent results while minimizing side effects. Your diet and training should be the primary driver of your desired results with this stack.

Benefits:

• Fat loss on a calorie deficit diet
• Muscle gains, including while burning fat
• Endurance, strength, and energy boost
• Faster muscle recovery

Dosing:

• Cardarine: 10mg daily for eight weeks
• RAD-140: 5mg daily for eight weeks

Possible side effects:

• Testosterone suppression
• Some liver stress
• Aggression or irritability

If muscle gains are your primary goal here, it’s possible to gain 10 lbs. While cutting, even a few pounds of lean muscle can be gained. If your body fat is currently at the high end (around 20%), this stack can see you drop 10% body fat.

What about PCT? Depending on how suppressed RAD-140 makes you, you may get away with no PCT on this cycle. However, if you raise your RAD-140 dose above the recommended 5mg, PCT will almost always be required using a standard SERM protocol.

Bulking stacks

Cardarine is rarely considered a bulking PED, but it can have its uses in a bulking cycle where your goal is for some very lean gains with minimal fat. When stacked with an anabolic steroid, Cardarine is often used as a supportive compound. I like how it supports cholesterol levels using an AAS that kills your cholesterol, like Trenbolone.

Other bulking stacks you can consider with Cardarine without diving into the world of anabolic steroids include YK-11 or even the RAD-140 stack I listed above with a higher dose of RAD to facilitate muscle growth (just be aware that suppression will be more severe).

Non-suppressive stack (Cardarine + Ibutamoren)

If avoiding testosterone suppression is a priority as a male, you can look at stacking Cardarine with MK677 (Ibutamoren). Ibutamoren is a Growth Hormone Secretagogue. It is not a suppressive PED (even if you’ve read that it is – this is false!). So, this is an excellent non-suppressive stack that can deliver surprisingly powerful results.

Benefits:

• Muscle gains and muscle retention
• Faster recovery and improved sleep
• Endurance and energy are retained in a calorie deficit
• Increased bone density
• Appetite increase (you might see this as a negative if you’re cutting)

Dosing:

• Ibutamoren: 10-20mg daily
• Cardarine: 10-20mg daily
• Cycle length: 8-12 weeks

This stack can be either used for bulking or cutting. If muscle gains are your primary goal, you’ll look at the higher end of the dosage range for each PED.

Possible side effects:

• Joint stiffness
• Water retention
• An increase in appetite can make it hard to diet

If you’re in a calorie deficit, you’ll notice how these PEDs work to preserve muscle. The increased appetite caused by MK677 can make it a challenge to stick with a strict diet, and some users find reducing the dose can help control this. Strength and endurance improvements are expected with the combined effects of both PEDs. Some users comment how niggling pains subside; this is thanks to MK677 and the impact of HGH speeding up muscle healing and strengthening bones and joints.

You will look bigger after this cycle, and a lot of this is, unfortunately, water retention. This will fade after the cycle, potentially resulting in a drop of 10 lbs or more of total body weight. No PCT is required as neither Cardarine nor Ibutamoren will suppress testosterone levels.

Cardarine PCT

Cardarine is one of the few PEDs where males don’t even have to think about doing PCT. That’s right, no post-cycle therapy! It doesn’t cause any testosterone suppression, so if you’ve done a Cardarine-only cycle, you can skip PCT altogether. Men won’t experience any reduction in testosterone levels during or after a Cardarine cycle. It has no hormonal effects at all. Naturally, you will need to consider PCT if you’re stacking Cardarine with just about any other PED because not many others have zero suppressive qualities like this one. Females never have to think about PCT, regardless of what PED is used. The same applies to Cardarine.

Cardarine Side Effects

Usually, I’d want to talk separately about the side effects of any PED as it relates to females and males because, as you’d certainly know, adverse effects can be very different. But this isn’t the case at all with Cardarine! Due to the complete lack of hormonal effects, people will have similar experiences regarding the downsides of Cardarine.

The good news?

Cardarine is one of the most “side effect friendly” PEDs you can use, at least in the immediate term. While using it, I experienced no side effects, and I know plenty of other bodybuilders with the same experience. However, some known adverse effects are reported by some Cardarine users. Plus, we have the more unknown potential long-term effects that we don’t have solid data on yet (and may never have). Here’s what to look out for:

Short-term side effects

There are few known short-term side effects of Cardarine. This would be one of the most side-effect-friendly compounds out there, and using it at recommended doses will see most people generally free of side effects. This is not a steroid (it has no steroid-like properties), so there are no androgenic or estrogenic effects to worry about. One of the most appealing things about using Cardarine for fat loss and shredding is that you don’t suffer from any water retention. Cardarine can decrease the fluid level in the cells and promote a more defined and vascular physique for those on a cutting cycle.

People will respond differently, as with any substance, and you will hear about varying short-term side effects. One of those is insomnia or difficulty in falling asleep. Other reported temporary side effects include headache and fatigue. Most individuals who are unlucky enough to suffer from these side effects note that it happens during the first stages of the cycle and usually subsides after a short time.

Long-term side effects

The offending study that led to the discontinuing research on Cardarine involved mice who were given very high doses of Cardarine. Although the physical performance of the mice was considered considerably enhanced, they rapidly developed cancers in several organs at these very high doses. As a result, Cardarine was not deemed safe for further research with humans.

Naturally, any time the word cancer appears, it requires taking a step back and considering whether a substance is a high risk. Yes, the study used doses that are well beyond what we would ever consider using, but the risk of cancer still needs to be considered as a potential risk factor for Cardarine. Aside from this, there is no data about any other long-term health risks or side effects from Cardarine based on current knowledge. Avoiding high doses is key to reducing risk as much as possible.

Hepatotoxic side effects (liver toxicity)

Cardarine is not known to cause any toxicity to the liver. Minor changes to liver values were recorded during some of the trials. While, once again, we need a lot more research to find out precisely what, if any, impacts Cardarine has on the liver, there’s a possibility people with existing liver conditions could be vulnerable to more dangerous fluctuations in liver enzyme values. So, if you have an existing liver condition, you might want to rethink using Cardarine until more is known.

Consuming alcohol or many types of prescription medications (especially anti-depressants) while using Cardarine is strongly advised against, and the effects on the liver of doing so are unknown. There is a circumstance where Cardarine can pose a greater risk to your liver. That is when you stack it with one or more other compounds like steroids or SARMs.

Cardarine promotes cellular proliferation (cell growth and cell division), so other compounds that negatively impact the liver could see this serious side effect multiplied and worsened when combined with Cardarine. This will bring about a significant change in liver enzyme values for the worst, and in extreme cases, could lead to liver failure. No research is available to show precisely how Cardarine could intensify liver toxicity, so if you’re determined to stack Cardarine with liver-stressing compounds, try and stick to the shortest possible cycle to reduce this risk.

Cancer

The most concerning finding has been the cancer development in mice during a trial many years ago. Again, it needs to be emphasized that excessive doses were used, and as far as anyone knows to date, it is the very high dose of Cardarine that resulted in cancer development. Could this potentially happen in humans who repeatedly use lower doses of Cardarine? We won’t know without any proper studies. The fact that Cardarine has some activity that results in cancer formation, even if only at excess doses, makes it a compound many will think twice about using.

Most people will use Cardarine for around eight weeks and take a break between cycles (ideally). This is a big difference from the research’s 2-year, high-dose cycle. Put it this way: Any medication that resulted in cancer the way Cardarine did in its study would be extremely unlikely ever to be approved for human use. Cardarine is unlikely ever to see FDA approval, whether or not this cancer risk is a factor at lower doses and shorter-term use.

Insomnia

It’s not uncommon for Cardarine users to report difficulty sleeping, especially towards the beginning of the cycle. But as Cardarine isn’t a stimulant, despite its powerful fat-burning and energy-inducing effects, it would not have the same impact on sleep and rest as a potent stimulant drug would have. So what could cause insomnia and sleep difficulties in some Cardarine users? There’s no research indicating insomnia should be a side effect, so it’s very likely a personal response between each individual.

Indeed, most people who use Cardarine don’t suffer from insomnia. One possible solution that has worked for some people is to take your dose first thing in the morning. Although Cardarine isn’t known for causing the highs and lows associated with stimulant substances, energy levels should be relatively stable throughout the day regardless of when you take your dose. If you are experiencing insomnia-related side effects, some users find that taking a zinc and magnesium supplement before sleeping helps alleviate this problem.

Women-specific side effects

As Cardarine is not a steroid and has no steroid-like properties, women won’t suffer from the virilizing and other side effects that come from compounds with androgenic activity. This means that females on Cardarine will have the same side effect risk profile as male users since this is not a hormonal compound and does not affect estrogen or testosterone.

There’s no worry about masculinization signs like voice deepening and hair growth. Most women who use Cardarine do so to lose fat, but whether the steroid Anavar is a better option should be considered. Anavar is one of the best female-friendly compounds, with minimal side effects. Its side effect profile for women may be less risky than that of Cardarine when considering the cancer-related data on Cardarine.

Is Cardarine safe?

Cardarine has been put through a few clinical trials, and none of these trials have revealed side effects in human participants. However, with so few trials done to date, there’s nowhere near enough clinical data for it to be known whether there will be any new longer-term health risks identified with Cardarine.

It is known that there could be a potential cancer risk with prolonged or high dose use of Cardarine, based on rodent studies. However, more data is needed to confirm whether this could happen at low doses over the long term. In other words, much more thorough research is required, which means using Cardarine still comes with possible and actual risks to health and safety.

Cardarine Supplement

Cardarine is essentially an experimental compound with little research into its effects. It is known it has caused severe health risks in lab results, including cancer, and this unpredictability and mystery around its possible hazards make it a huge risk to use. This is why I strongly suggest checking out Cardarine alternatives instead.

Many replacements can offer similar or even better benefits than Cardarine – without the serious risks to your health that Cardarine presents both in the short and long term. With all this in mind, if you want to head straight to the premier alternative to Cardarine on the market right now, look no further than C-DINE 501516.

Why I Like It: It eliminates the famous cancer risk of Cardarine without compromising on my results.

It’s Worth Noting: You’ll get the best ripped and vascular aesthetics from C-Dine if you’re already at a low body fat percentage.

I wanted to like and use Cardarine because I know how good it is. But there’s a BIG but: The cancer risk identified in rat studies just put a big red flag over Cardarine for me. Finally, we have an excellent and SAFE alternative to Cardarine in C-Dine. Like Cardarine, C-Dine is about achieving maximum endurance, stamina, and fat-burning without losing lean muscle. This is a formula for the athlete and the cardio enthusiast; expect incredible endurance and stamina that you can use either to break your athletic records or to supercharge the loss of stubborn fat.

C-Dine covers all the primary benefits of Cardarine with the peace of mind that not only is the cancer risk gone, but those other Cardarine sides won’t weigh on your mind either (heart enlargement, liver stress, and brain cell damage, to name a few possibilities). And while Cardarine’s fat-burning effects are respectable, I find C-Dine to be even better – and C-Dine, hands down, promotes vascularity and muscle hardness much more than Cardarine ever could. Finally, let’s talk about cycle length: Burning fat and keeping it off is a long-term goal, and I never felt comfortable using Cardarine longer than 8-10 weeks max, but C-Dine is safe to use for as long as you want without damaging your health. If you decide to use C-Dine, I recommend buying it here.

Cardarine Results

Your results will depend just as much on Cardarine’s effects as your efforts. Are you considering taking Cardarine and sitting back, hoping the fat will drop off? That is not going to happen. Or are you not willing to take advantage of Cardarine’s substantial boost to endurance by extending your workouts, training, or sports performance? You’d be wasting your time using it. But if you’re prepared to go the distance, you’re unlikely to be disappointed with the results.

Cardarine starts working very quickly, and you should begin noticing significant endurance improvements within just the first few days of a cycle. So whether you’re a weight lifter or endurance athlete, this boost in stamina will allow you to work or compete for longer and at a higher intensity. The flow of results from this will be your specific goals: To beat a time record, lift heavier weights with more sets and reps resulting in faster muscle growth, or boost your overall fitness and performance.

This is a very versatile compound that will suit anyone from bodybuilders to physique competitors, especially those undertaking endurance exercises like running and CrossFit, where you want to push on as long and hard as possible by staving off fatigue.

Runners will see faster times and much-improved cardio performance, which will start taking effect quickly as Cardarine starts working fast. You will see positive changes within the first week or so, with improvements continuing to ramp up for the duration of your cycle. Athletes should be able to kick through previous personal best times when using Cardarine.

Cardarine results for men

Men will enjoy excellent endurance benefits on a Cardarine cycle. Significant endurance boosts mean a new capacity for working out, training, playing sports, running, or just doing anything that involves pushing your cardiovascular system to the limit. Men aren’t going to see substantial muscle gains on Cardarine; it’s just not that type of compound.

You could burn a nice amount of fat in the 5lbs range. But most men use Cardarine to run further, beat times, and train harder. Whichever other compounds you stack Cardarine with, its ability to push cardio performance further will multiply the results you’d usually get with any other compound. Cardarine is for the dedicated performance athlete and the person committed to regular, high-intensity cardiovascular exercise, regardless of the type.

Cardarine results for women

Women can see very similar results and effects from Cardarine as men do. Since Cardarine is not a steroid and has no steroid-like properties, its activity in the body is not male or female-specific. Naturally, women will also see the level of results that correspond with the associated training and diet use in a Cardarine cycle. If you’re a runner, you can run further and harder before tiring.

The same goes for cycling and any other long-distance endurance sports. Even just heading to the gym on the treadmill will see you smashing through previous records, and women will find noticeable fat loss within the first month of using Cardarine if their diet supports this goal.

Despite its effectiveness, it’s widely believed that Anavar (an anabolic steroid) is a better and safer option than Cardarine for women. Anavar is the most mild and female-friendly steroid, and its use at low doses can result in no side effects for women. It’s also not known to have a cancer risk like Cardarine, and that’s the main reason many women will select Anavar instead of Cardarine.

Lean muscle mass results

Cardarine has some anabolic effects, which can lead to small gains in lean muscle. However, since most people will use Cardarine to lose fat, a low-calorie diet is usually consumed, and this is hardly compatible with putting on muscle. One study showed a slight gain in lean muscle of 2.8 lbs over 12 weeks at a 10mg dosage. So, Cardarine can certainly not be considered a compound to use for any serious bulking purpose, at least not on its own.

Stacking Cardarine with any SARMs or steroids that promote more powerful lean gains can play a beneficial supporting role in increasing endurance and cardiovascular performance. For the minority who might want to see how much muscle can be gained with Cardarine alone, many will find the mild to moderate gains to at least be clean and long-lasting. There won’t be any water retention, and the gains will contribute to increased muscular definition and vascularity.

Cardarine’s muscle retention benefit is also significant to note. You should not see muscle loss while intensively burning calories with your newfound endurance and stamina.

Fat loss results

Fat loss results with Cardarine will vary. If you take Cardarine but put little effort into working out and don’t change your diet to facilitate weight loss, then it goes without saying that your results will be disappointing. No matter how powerful Cardarine is, you will struggle to meet any goals if excessive calories are consumed.

Those with an average body shape (including being out of shape) can significantly reduce body fat before using Cardarine. It’s generally easier to lose fat from a normal or slightly higher-weight position than to cut down those final percentage points. The latter will typically require a more potent compound, including steroids.

But if you’re not at the very extreme end of fat loss goals, Cardarine can have you losing 10% of your body weight over a 12-week cycle. This results in a noticeable change in body composition and muscle definition, and abdominals can become more prominent. At the top end, some users report up to 8 pounds of fat loss on a shorter 8-week Cardarine cycle, taking 20mg. This can rival some steroids and SARMs, and even the famous fat burner, Clenbuterol. But you’ll need to work hard to get that level of fat loss in such a short space of time and work hard to keep it off once your cycle ends.

You don’t have to do a 12-week cycle of Cardarine if you aren’t comfortable with that length because decent fat loss results can be achieved in a very short cycle. Some users find that just four weeks full of intensive workouts combined with a moderate Cardarine dose brings about body fat reductions in the 5% range. As you would expect, if you want to keep that fat off once you stop using Cardarine, your diet needs to be well managed, and you’ll need to keep up your cardio training.

Cardarine provides a significant boost to fat loss that would otherwise take many, many months to achieve, if at all, but you will still need a way to maintain your weight loss since Cardarine will not be a compound that you can keep using over the long term.

Endurance results

Cardarine’s most powerful effect is its significant boost to muscular endurance. Cardarine users will notice the ability to work out much longer and at a higher intensity before fatigue starts. You’re not a mouse, but you might find it impressive that when mice were given Cardarine for three weeks, their endurance increased by 68%. If you’re already fit and regularly partake in something like long-distance running, this can be a substantial boost and will have you beating your regular times early on in the cycle.

What’s most impressive is that your cardio gains come on almost instantly after taking your first dose. That means you can get into it from the first day of a cycle. You will notice your regular workouts feel more effortless. At the point you’d usually need to stop, you’ll feel that there’s still plenty of fuel left in the tank, and you can keep going. These effects will be considerable for most people. Of course, you will need to push yourself to the limit during training to notice this.

Improved cholesterol

Cardarine has shown it can raise good cholesterol levels while reducing bad cholesterol levels. This is a benefit we rarely see with any performance-enhancing compound. Even at low doses of 10mg per day, one study showed an LDL decrease of 7% and an impressive increase in HDL cholesterol levels by 17%.

There’s another side to Cardarine’s cholesterol benefits: This can be a compound you use for cholesterol support when using substances that cause cholesterol to increase. Steroids are notorious for their negative impacts on cholesterol, sometimes to dangerous levels. Some SARMs also have similar effects. Stacking Cardarine with substances that result in negative cholesterol effects may reduce the risk to cardiovascular health.

Trenbolone is a prime example of stacking Cardarine to get a cholesterol benefit. Tren comes with serious cholesterol risks, and some people avoid using it for that reason. Adding Cardarine can make Trenbolone a more usable substance for anyone who would otherwise avoid it for this reason.

Cardarine reviews

There’s no shortage of reviews being shared by Cardarine users. There are reviews right across the spectrum ranging from exceedingly positive and joyful at the results to disappointed and discouraged. Those in the middle who feel they got OK results can probably do better with other compounds.

Positive reviews

There are thousands of comments, reviews, experiences, and before and after photos shared about Cardarine. The majority lean towards the positive, which could be expected with a compound that normally doesn’t cause immediate side effects that can otherwise tar the experience of using it. People can focus on progress and results rather than mitigating debilitating side effects, as is so often the case with other substances.

As expected, increased cardio capacity and fat loss are the results that everyone focuses on. There’s a strong pattern of people involved in regular intensive sports like martial arts, long-distance cycling, and running who find Cardarine’s endurance benefits substantial.

Negative reviews

It can be surprising that many negative reviews about Cardarine focus not so much on side effects but on the lack of results. Some people believe it is just not effective enough to justify using. Some of these people might be experienced steroid users who are used to more powerful results and find their Cardarine results disappointing by comparison.

Others use Cardarine and expect extreme fat loss within a short time. Those sorts of expectations will often lead to disappointment. People focused solely on fat burning often state that Cardarine is a great option for endurance athletes, but there are better choices for fast and extreme fat burning.

Overall, negative reviews of Cardarine are often based on personal expectations and misunderstandings of what it can and can’t do. Ultimately, Cardarine will always be more suitable for some people than others.

Where to Buy Cardarine?

Despite its known risks, Cardarine remains one of the more popular PEDs you can buy through research labs. But its availability (and legal status) will depend on your location. Cardarine is easily found and purchased online in the US and most major countries. And yes, you can technically legally buy it through reputable online research chemical suppliers.

Cardarine is sold for research purposes only, but there is little to no scrutiny (for now) of who is purchasing it and how it’s being used. Your main concern will be finding a high-quality, trustworthy supplier. You will want to avoid buying from anywhere that doesn’t have a good reputation because:

• The quality of the Cardarine can be very low or even contaminated, resulting in unexpected side effects and poor results.
• Scams exist; you may pay a supplier and never receive your Cardarine in the mail.
• Despite what the label says, there may be no actual Cardarine in the product.

I can not stress this enough: Do your research and only buy from trusted sources if you want the best and pure quality Cardarine.

Pharmaceutical grade Cardarine for sale

As Cardarine has no FDA or other approval for any form of medical use – and likely never will due to the alarming cancer developments in rodent testing – there is no manufacturing of Cardarine in any pharmaceutical labs anywhere in the world. It is available exclusively as a research-only chemical and will be the closest you can get in terms of quality to pharmaceutical grade.

Research chemical companies sometimes have their products’ purity checked by third-party testing facilities and provide the documentation online. Many will then promote their Cardarine as being 99% purity (and sometimes 99.9%), but you should still do your due diligence as there is little in the way of stopping suppliers from making these claims.

The best way to have the most confidence in buying top-quality Cardarine is to stick with tried and tested SARM suppliers with a long-term positive reputation among the bodybuilding community.

Underground lab Cardarine for sale

If you have experience in buying anabolic steroids from underground labs, you might think to look there for SARMs and other similar compounds like Cardarine. However, because Cardarine is technically legal for research chemical labs to sell, there is not often a need to seek out underground sources. Cardarine is a compound with high popularity in the bodybuilding and fitness community, so most research lab suppliers will find it beneficial to keep it in stock, making it almost unnecessary for Cardarine to be produced and sold by underground suppliers.

If you come across underground lab-produced Cardarine, the same checks and balances should be carried out to determine (as well as you possibly can) that the Cardarine is of high purity. However, underground sellers are unlikely to take the steps that research chemical labs do in having their Cardarine purity tested by third-party labs. Nothing stops these suppliers from promoting their products as 99% purity, even if it does not come close to that. As always, it’s buyer beware, but your best bet to find the highest quality Cardarine is to stick to the most reputable research chemical lab suppliers rather than hitting the underground market.

Availability of Cardarine

Cardarine is widely available through research chemical suppliers. If you’re in the US, you’ll find many online research chemical sellers who stock Cardarine as one of their most popular products. I prefer Cardarine in liquid form, as it’s easier to take, measure the dose, and get an accurate dosage each time. However, powder and pills are also available from some suppliers. Again, the quality of any of these products can vary drastically between sellers.

Is Cardarine legal?

With its well-known ability to significantly enhance performance and body composition, Cardarine is listed as a prohibited substance by all the major world sporting anti-doping organizations, much like anabolic steroids. So, if you’re a competitor of any sort and are likely to undergo drug testing, Cardarine would not be a legal substance for you. As for the average amateur bodybuilder, athlete, or fitness enthusiast? Cardarine won’t present legal problems as SARMs or other non-anabolic steroid products will.

Typical pricing

Liquid Cardarine typically comes in 30ml bottles of 20mg/ml concentration, which can be bought for around $60 from online US-based suppliers. I have seen products with half that concentration – just 10mg/ml – for the same price from other labs. The variations are due to the lack of regulation around selling these research chemicals. In short, no one checks the quality or manufacturing process, and sellers can effectively charge whatever people are willing to pay. It all comes down to shopping around, finding suitable suppliers through word of mouth, and not necessarily going for the lowest price you can find. Ordering bulk vials will usually yield a nice discount compared to a one-off purchase.

Cardarine FAQs

How long does it take for Cardarine to start working?

Cardarine is a very fast-acting compound with a half-life of under 24 hours. Noticeable body fat loss should start being seen after the first week, but this will heavily depend on your diet and exercise. You should notice a boost in endurance and energy within your first day of taking Cardarine.

How long can you cycle Cardarine?

There’s no standard rule on how long a Cardarine cycle should be, but many users will keep in mind the issue of cancer development in rodent studies, and so limit cycles to minimize risk. Most Cardarine cycles will be between 6 and 8 weeks long, but some users will run Cardarine for 10 or 12 weeks to meet specific goals.

When should you take Cardarine?

The time of day you take Cardarine is not so important, but it should be taken at the SAME time every day so you maintain a consistent level. Larger doses, such as 20mg, can be split into a twice-daily administration.

What does Cardarine do for athletes?

Cardarine provides a massive boost to endurance, and one of the ways it does this is by boosting oxygen and nutrients to slow twitch muscle fibers, which staves off fatigue for more extended periods during exercise. Cardarine’s two main benefits for athletes are its big boost to muscular endurance and fat loss.

Do you need PCT for Cardarine?

Cardarine does not affect testosterone function, so you won’t need to do any PCT after using it. But if you stack Cardarine with any SARM or steroid that does cause suppression, you’ll need to plan for a PCT cycle.

Does Cardarine increase recovery?

Cardarine can have some benefits for improving recovery after exercise by helping more oxygen get to the muscles. Some users note that while on Cardarine, their recovery times are reduced, and there is a decrease in muscle soreness after intensive workouts.

How effective is Cardarine for cardio?

Cardarine is highly beneficial to cardio exercise; that’s considered its most significant benefit. You will notice that where you previously got fatigued during cardiovascular training, on Cardarine, you can push well past your normal limits and keep working out. This will lead to more fat burning, but you should also notice improved cardio performance after finishing a Cardarine cycle, as long as you exercise regularly.

Do you take Cardarine every day?

Yes, Cardarine should be taken every day of your cycle. It has a short half-life, so it’s recommended to take your dosage at the same time each day or to split it into two and take half in the morning and half in the evening. A break of several months is recommended between Cardarine cycles.

Does Cardarine help with running?

Yes, many people use Cardarine to boost running performance. Many Cardarine users will find that their distance and time can be substantially improved by using Cardarine, with the endurance benefits noticeable within hours of taking your first dose.

How long does Cardarine stay in your system?

Cardarine’s half-life is between 16 and 24 hours, but it can stay in your system for much longer and continue having effects up to 6 days after your last dose. Traces of Cardarine can be detected in urine tests during that time frame.

Will Cardarine give me cancer?

It’s understandable to be concerned about the past research history of GW501516, where cancerous tumors were found to commonly develop in studies on rats at extremely high doses and over long periods. The doses were potentially up to 1000 times higher than a human would use Cardarine relative to body weight. So, the risk of cancer at much lower doses of Cardarine is used for performance enhancement, while still not fully known due to the lack of scientific studies, and is not considered significant. It is still considered one of the safest compounds to use.

Does Cardarine raise blood pressure?

No, it has been shown to do the opposite. Some studies have discovered that Cardarine can reduce high blood pressure. This tells us that Cardarine does not work in a way that promotes a rise in blood pressure. Additionally, Cardarine can reduce heart disease risk by raising good cholesterol levels and decreasing bad cholesterol levels.

Final Thoughts

Most people use Cardarine to help boost endurance and stamina during exercise. This makes Cardarine excellent for any experience level. We can all benefit significantly from this performance enhancement, whether you are primarily weight lifting or mainly doing cardio work. A bonus effect of Cardarine is its ability to help burn fat. Cardarine helps the body more efficiently use calories for energy. Finally, Cardarine can support your steroid use by helping minimize the negative impact that steroids have on cholesterol, blood pressure, and cardiovascular health.

Cardarine is a PED that you’ll either take or leave. Opinions are typically all or none regarding the big C word – cancer. I feel it’s no more of a risk than all the other things we’re exposed to daily – but that’s MY opinion. Yours might vary, and I’m not here to recommend using Cardarine. After all, there are plenty of other potentially safer options.

From everything I’ve gathered and personally seen, 99% of people use Cardarine without issues or concerns. The results are exceptional, and if this is a road you choose to go down, I still haven’t met anyone disappointed with Cardarine’s benefits and results! The risks are downright scary, though, with the cancer word not going away, and we know by the fact that even pharmaceutical companies aren’t keen on pursuing Cardarine that the risks are real. While this is pretty much the only negative about Cardarine, it doesn’t get much bigger than this.
