Aromasin (Exemestane) is a potent aromatase inhibitor, which is what makes it valued so highly as one of the best PCT drugs by people who use anabolic steroids. Your primary use for Aromasin is to stop estrogen-related side effects, the most important being gynecomastia (gyno).
Aromasin is the favored aromatase inhibitor (AI) ancillary of thousands of steroid users. That’s not to say Aromasin is perfect or that some of us don’t have difficulties using it. But how does Aromasin compare to some of our other AI options? Are there any benefits in using Aromasin compared to other AIs, and what is the best dosage? All this and more is covered in my Aromasin PCT guide below! Let’s get started.
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 Aromasin?
Aromasin is a name just about every bodybuilder will be familiar with. If you’ve never used Aromasin, you probably know someone who has! Just about every steroid user will try this AI at least once, mainly if you’ve found others falling a little short of your expectations one way or another. And while the widespread opinion is to avoid using AIs for PCT, as you will see, Aromasin can be more of an exception than possibly any other aromatase inhibitor.
Exemestane, the active compound and chemical name of Aromasin, works by blocking the effects of estrogen in the breast tissue so cancer growth can be limited or stopped. This breast tissue-targeted estrogen-blocking action of Aromasin is helpful for bodybuilders who use anabolic steroids with aromatizing effects that cause estrogenic side effects – specifically gynecomastia (gyno) or male breast tissue enlargement.
When we let gyno take hold while using steroids, the effects are not only ugly and embarrassing to look at, but they can be impossible to get rid of without surgery. So, making use of an aromatase inhibitor like Aromasin is one of the most essential things a male steroid user must do.
A Quick Look at Aromasin
- Other Names: Exemestane (generic), Aromasyn, others.
- Primary Use: Estrogen control during cycles and occasionally in Post-Cycle Therapy (PCT) to manage estrogen rebound. Also prescribed for breast cancer treatment.
- Administration: Oral form (tablets). On-cycle dosage: 12.5-25 mg every other day (adjusted via bloodwork). PCT dosage (if used): 12.5 mg every other day for 2-4 weeks (combined with SERMs). Half-life: ~24 hours.
- Cycle Length: Primarily for estrogen management while on cycle.
- Benefits: Effective estrogen suppression during cycles (prevents bloating, gyno), no estrogen rebound after discontinuation (due to suicidal inhibition), may improve lipid profile slightly compared to Arimidex.
- Side Effects: Joint pain (from low estrogen), reduced HDL (“good” cholesterol), increased LDL, fatigue or mood swings, bone density loss (long-term use), liver enzyme elevation.
Note: Aromasin is a potent AI best suited for on-cycle estrogen control, not standalone PCT. While it can assist in PCT for severe estrogen issues, SERMs remain the cornerstone of recovery. Always prioritize bloodwork to avoid crashing estrogen and consult a healthcare professional. Misuse can lead to long-term hormonal imbalances and health risks.
History and Overview
Aromasin is a secondary treatment for advanced breast cancer treatment in postmenopausal women after Nolvadex has been taken for up to three years. Where women have not fully responded to Nolvadex and the cancer has progressed, Aromasin steps in to lower overall estrogen levels in the body to deprive the tumor of estrogen and attempt to stop its growth and spread.
Aromasin was only approved for medical use by the FDA in 1999, and it has since become a very popular AI worldwide. The developers of this AI were Pharmacia & Upjohn. Aromasin has been put through extensive studies to prove its safety and efficacy in treating breast cancer patients, with studies finding even with long-term use, only mild side effects were commonly reported.
Mechanism of Action
To understand how Aromasin works and, importantly, WHY it works that way, we need to understand the purpose of this AI for medical use. With the type of breast cancer this AI aims to treat, being one that needs estrogen for it to continue to grow, Aromasin’s core function is to stop estrogen in its tracks.
And how does that work? Estrogen receptors exist in the cancer cells, and the aromatase enzyme is needed as a key part of their functioning. Aromasin blocks the aromatase enzyme, so it can not apply its effects – but this doesn’t just happen in breast tissue (Remember: AIs like Aromasin are not selective!). This blocking of the aromatase enzyme will happen everywhere in the body. The result? A lowering of total estrogen levels. Aromasin has proven to suppress circulating estrogen levels, and more suppression occurs at higher doses[1].
Effects of Aromasin (Benefits) for Men
While the medical use of Aromasin seems irrelevant to any of us males who are healthy (mostly young) bodybuilders using steroids, it’s vital to understand the connection: Aromasin works to block estrogen to deprive the cancer of what it needs to grow.
Think about it:
The reason Aromasin is used in postmenopausal women is because their body has stopped producing estrogen at levels of younger women. Hence, crashing estrogen in older women is a vastly different concept to what we males will experience from Aromasin’s estrogen-lowering effects. That’s why dosage control is paramount to the effects you’ll experience with Aromasin. And I mean both good and bad effects!
Here are the positive effects of Aromasin once your dosage is dialed in for your specific needs and your response: The main purpose of using Aromasin is to combat estrogenic side effects. You will use this AI to prevent and control:
- Water Retention
- Gynecomastia
- High blood pressure resulting from fluid retention
Aromasin may also be used for testosterone stimulation following AAS use (PCT). It has been shown to stimulate LH and FSH; however, the associated estrogen-lowering effects will always make using AI as a sole PCT compound challenging.
Importance of Aromatase Inhibitors in Bodybuilding
With some of the most popular anabolic steroids being hormones that aromatize (convert testosterone to estrogen), AIs are always kept on hand and ready to use on these steroid cycles. Mostly, this refers to AAS like:
- Testosterone
- Dianabol
- Trestolone
Nandrolone steroids (Deca, NPP) can also bring about raised estrogen levels when they are used with testosterone, and most Deca users will be taking Aromasin or another AI.
At its most basic, an AI does just what its name implies: It inhibits the aromatase enzyme. That’s the enzyme that’s responsible for the conversion of testosterone to estrogen. When the drug blocks the enzyme, conversion can not take place. Without that conversion of hormones, you can avoid, reduce, or reverse the symptoms of high estrogen during a cycle:
- Water retention (and associated high blood pressure)
- Gyno
Does this mean you will need an AI while running any or all of the above aromatizing steroids? No! We can and do get away with (for example) running a testosterone-only cycle, sometimes at high doses of 800mg/week or more, without the need for an AI.
But take note!
YOU might need an AI at 600mg of testosterone, while others can run 1000mg without having estrogenic effects requiring control. As a general rule, the higher the dose of AAS (either one or a stack), the more testosterone will be converted to estrogen.
So, while aromatase inhibitors are essential for bodybuilding steroid cycles, you don’t have to take one from day 1 – watching for the onset of estrogenic effects and then taking the AI at an appropriate dose is the strategy for most users.
Aromasin for Gyno and Estrogen Control
Aromatase inhibitors, including Aromasin, have become a vital tool for steroid users in the battle to combat estrogen-related side effects during a steroid cycle. One of the most feared estrogenic side effects from steroids, which aromatize, is gynecomastia – male breast tissue enlargement. If not adequately controlled, then this condition can become irreversible through any means besides invasive surgery.
Additional estrogen-related side effects we need to control with an aromatase inhibitor include water retention and the high blood pressure that can come with allowing water retention to reach a high level.
AIs like Aromasin, Arimistane, and Letrozole work more universally than another type of drug that’s popular with steroid users: SERMs, which are selective in the tissue they target. Aromasin, conversely, can lower overall serum estrogen levels by blocking the process of aromatization. When the steroids you’re using convert testosterone to estrogen, this is an aromatizing process and one that most steroids will cause.
Aromasin is a powerful and effective way to lower your estrogen levels while on a steroid cycle so you can reduce or even completely prevent estrogenic side effects like gyno, and this drug is known to be very effective at lowering estrogen. Studies show that Aromasin can lower estrogen levels and increase male testosterone concentrations[2]. It was found that the drug works fast to start suppressing estrogen, with concentration of the drug being at its highest level just one hour after a 25mg dosage, and the maximum level of estrogen suppression was seen at the 12-hour mark.
Aromasin for PCT
Aromasin won’t be your first choice for PCT use unless you have no access to SERMs. Typically, we would avoid AIs during PCT. Still, among all the AIs, I would say Aromasin is the most suitable AI for PCT because it can stimulate testosterone production by releasing LH and FSH.
On the other hand, you’ll have the problem of potentially crushing your estrogen levels during PCT, which will cause all sorts of havoc with your testosterone recovery.
My opinion?
Use Aromasin cautiously if you’re set on using it during PCT, and always follow it with Nolvadex.
Doses
With Aromasin having its only medically approved use for the treatment of breast cancer in women, doses used for that purpose are not of great relevance to us as males will respond somewhat differently. And secondly, women treating life-threatening breast cancer are less concerned with any negative effects of Aromasin than we are.
With this in mind, a study that focused on the minimum effective dose of Aromasin in women found that doses of 2.5g to 5mg daily were very effective at reducing circulating estrogen. Still, even a dose of 0.5mg daily resulted in some estrogen suppression[1].
Aromasin dosage on-cycle
With this being the number one use of Aromasin (combating on-cycle estrogenic side effects), standard dosages have become well-established. However, my preferred dosage might not work as well for you. It depends on:
- The dosage of the steroids being taken
- How sensitive you are to aromatization as an individual
I like to start at just 6.25mg per day. This is just one-quarter of a 25mg tablet. You could also take 12mg every other day. Another strategy that works for a lot of guys is to only take Aromasin on the days you’re injecting – this could be once every two to three days at a dose of 12.5mg to 25mg as required, according to your estrogenic side effects.
Aromasin dosage for PCT
You’d only want to consider using Aromasin for PCT in rare situations. Generally, we don’t use AIs for post-cycle therapy to recover testosterone function – SERMs are much more effective and valuable for your PCT protocol.
So, when might you think about including Aromasin during PCT? If you get bloodwork done and find that your estrogen levels are too high AND you’re seeing side effects, then a low dose of Aromasin might be considered – but I’d say be very careful with this because the risk of crushing your estrogen is real.
Should you use Aromasin on its own for PCT? You can use it briefly, but I’d still want to use it alongside Nolvadex. I wouldn’t expect a full HPTA recovery solely from Aromasin, but you may have a different experience! Remember – Nolvadex and Aromasin are often used together in medical situations for breast cancer treatment as they complement one another. One example of PCT is Aromasin, used for only two weeks at 25mg daily. Nolvadex can be used for four weeks at 20mg to 40mg.
Female Aromasin dosage
Women who use steroids don’t have the same concerns as men when it comes to estrogen levels. Additionally, Aromasin is a very powerful inhibitor of estrogen, so young women will not want to reduce estrogen levels to the extent that this drug can.
Some females who use steroids and are concerned about water retention might choose to use Aromasin at a low dose of just half a tablet twice per week, adjusting as necessary, and many women will find even this amount is at the high end. This equals 12.5mg per dose with a 25mg tablet.
Dosing schedule, half-life, and PCT length
Aromasin has a short half-life of about 24 hours in women. It’s debatable whether the half-life is, in fact, the same in males. One study reports that this AI’s half-life in males is about 9 hours[3].
The opinion is split on whether taking it every day or every other day is best. Still, like always, I recommend experimenting with splitting the dose and frequency of administration. I like a once-daily administration of this AI to keep levels stable, but I’ll take a low dose each day and closely monitor the effects. Many guys take it every other day and find it effective – you don’t know until you try!
And let’s not forget this:
With Aromasin being a suicidal aromatase inhibitor, we don’t have to taper it down like you often need to with Arimidex because Aromasin won’t give you that estrogen rebound. Once your dosage is dialed in, you can stop taking it before starting PCT.
Proper administration and timing
The time of day you take Aromasin is a personal preference – the official FDA guideline when this AI is prescribed for women is to take it once daily with a meal, which may improve absorption. In my experience, it’s just easier to take the dose in the morning with breakfast. I don’t have to think about it again for the rest of the day.
I have heard of guys saying they find it hard to sleep after taking Aromasin in the evening – but I take that with a grain of salt because we are using AAS that can so often disrupt sleep quality.
Aromasin vs. Other PCT Options
Is Aromasin going to be your best choice for PCT? In most cases, the answer is no. Can you imagine crushing your estrogen levels during PCT? That’s the risk if you use Aromasin as the sole PCT compound. It’s also not considered as potent enough to stimulate testosterone production as the very popular PCT SERMs are. Let’s compare Aromasin to a SERM and two other AIs:
Aromasin vs. Nolvadex
Nolvadex is a widely used SERM and a very effective PCT compound. It’s the drug that is prescribed to breast cancer patients for two or three years before Aromasin.
These two drugs work very differently, yet both can address many of the same issues we face:
- Both will work to help prevent and reverse gynecomastia
- Both can stimulate testosterone production
Nolvadex, however, will be the more potent and effective PCT compound of these two options. Nolvadex will not help you with water retention, though – that’s where you’ll need to use Aromasin on cycle. A protocol of using Aromasin on cycle and Nolvadex for PCT is often all any steroid user will need as these are two of the best ancillaries available.
The two main goals of PCT are to help your testosterone recovery and to retain the gains you’ve made on your steroid cycle. Both Aromasin and Nolvadex are known to work very well to reduce your estrogen levels and associated side effects while you’re using steroids – but what about after your steroid cycle during post-cycle therapy?
The SERM Nolvadex is possibly the most commonly used drug for post-cycle therapy to stimulate testosterone production and help get your normal hormonal function back on track following the extreme testosterone suppression that steroids cause.
In addition to helping lower your circulating estrogen levels while on cycle, Aromasin also has the beneficial effect of stimulating natural testosterone production, making it appealing for PCT purposes.
One of the stand-out factors of this AI compared to some of the older (though still popular) products like Arimidex is that it can also increase Insulin-Like Growth Factor-1 (IGF-1), which is something that other AIs are not known to be able to do. This increases your overall anabolic state, which is going to be critical for maintaining your gains, which can easily fall away after your steroid cycle if you descend into a more catabolic state where muscle tissue is lost.
So, while this looks to make Aromasin a very appealing PCT choice, it’s not quite that simple, and in fact, the very potent estrogen-lowering effect of Aromasin can prove to be its downfall for PCT use. While we certainly don’t want higher than normal estrogen levels (men should always have a very small amount), suppressing it completely or to extremely low levels like Aromasin can result in great difficulty in testosterone production going back to normal levels because that process does require some amount of estrogen. It’s possible that Aromasin is just too powerful in the estrogen suppression process to be of great use during PCT.
This is why a SERM like Nolvadex is most often used and recommended for PCT over Aromasin. For most anabolic steroid users, besides the most hardcore and advanced, Nolvadex is all you will often need, and an AI may not be necessary at all even though more and more steroid users are claiming that AIs are essential, especially for controlling water retention.
This side effect can and should be addressed by the diet as well, and with some effort, most steroid users can find that the use of Aromasin during PCT is not necessary at all or only required at very low doses. Aromatase inhibitors are best used where they provide the most benefit, and that’s during a steroid cycle to protect against both estrogenic and progestin side effects.
Aromasin vs. Arimidex
Aromasin is a suicidal aromatase inhibitor, while Arimidex is a non-suicidal AI.
At its most basic, this means:
- Aromasin permanently inhibits the aromatase enzyme
- Arimidex binds temporarily
What does this mean for you? Arimidex can bring about a rebound in estrogen once any unbound aromatase enzymes are free – and this generally requires tapering the dosage before stopping. We can use Aromasin at a single dose and stop all use without any tapering, and you can expect no estrogen rebound. Aromasin is a more powerful AI than Arimidex, and while this has some benefits, it does bring an increased risk of reducing your estrogen too low.
Aromasin vs. Letrozole
Letrozole won’t give you the benefits we get from Aromasin. That’s because Letrozole is primarily helpful for mitigating gynecomastia. And Aromasin is just a way more tolerable drug than Letrozole for just about everyone.
Some guys will call Letrozole the nuclear option: A last resort or a desperate option to eliminate gyno fast. Letrozole is possibly the most estrogen-crushing AI we can use, and it can very quickly have you at dangerously low estrogen levels with no erectile function and feeling very lethargic. And that, for me, is the significant difference between Aromasin and Letrozole: Aromasin gives you more wiggle room to get things wrong with your dosage and is a less potent AI than Letrozole.
Aromasin Side Effects in Men
Most users will tolerate Aromasin, and its officially listed side effects for female medical use are mostly unlikely to apply to us. So what should you consider when it comes to possible Aromasin sides?
Cholesterol
The great thing about Aromasin is its lack of severe adverse effects on cholesterol levels compared to most other AIs. While Aromasin can raise cholesterol slightly in some users, studies show its effects are often neutral (neither raising nor lowering cholesterol)[4]. I’d say the top reason I like Aromasin is its reduced impact on cholesterol compared to other AIs. This can make all the difference when using it on-cycle with cholesterol-increasing AAS.
Most of the concern for steroid users is that steroids themselves often hurt cholesterol, so even if Aromasin only has a mild impact on your cholesterol as an individual, this could be alleviated much more substantially while you’re using a cholesterol-impacting anabolic steroid. So, if you know you’re prone to cholesterol issues, keeping close track of it is already going to be a priority while you’re using steroids and should be done even more so if you’re making use of Aromasin or any other aromatase inhibitor.
You’d have to be doing regular bloodwork to compare your cholesterol values before and during Aromasin use. Still, I’ve always been confident that this AI does not worsen my cholesterol profile.
Low estrogen
Most of the complaints I hear from guys taking Aromasin relate to low estrogen symptoms. If you’re not prepared for the signs of crashed estrogen, you can be in for a shock! We guys need a healthy (although small) constant level of estrogen for healthy functioning – your number one goal with Aromasin is not to screw that up!
Without careful use of Aromasin, you can quite easily bring about a drastic and fast reduction in estrogen levels, and with that comes some pretty unpleasant side effects that can be somewhat similar to low testosterone:
- Low libido
- Erectile dysfunction
- Anxiety and depression
- Inability to concentrate
- Loss of energy
- Painful joints
Aromasin has proven to be a very safe drug. Studies with humans have shown that a single dose of up to 800mg produced no serious effects, and even longer-term daily dosing at 600mg has been tolerated well.
Joint, bone, or muscle pain
Estrogen is essential for bone mineral content and bone health, but the short-term use of this drug by steroid users is unlikely to cause a noticeable impact in this area. If you allow your estrogen levels to drop too far, some joint and bone pain might be experienced, and this usually disappears once your use of Aromasin stops.
Bone mineral content
One of the side effects bodybuilders and athletes can be most concerned about is the potential for Aromasin to lower bone mineral content, which can lead to a higher risk of fractures and osteoporosis. But it should also be remembered that many steroids improve bone mineral content, so this Aromasin downside can be offset somewhat and is, like so many side effects, thought to be a very individual response to the drug where it could be a concern for some users but not at all for others.
Tiredness
Another effect of reducing estrogen below a certain point is the onset of fatigue, sometimes to a chronic level. Modifying your dosage of Aromasin can get this unwanted side effect under control.
Androgenic side effects
One aspect that can come as a surprise to new users of Aromasin is that it is capable of exhibiting mild androgenic side effects. This is a steroidal aromatase inhibitor, unlike other AIs used by anabolic steroid users, which are usually non-steroidal.
It will take higher doses of Aromasin for any androgenic effects to become noticeable, though, and they would almost certainly be weak, such as mild acne, which could be barely noticeable for many people. Those with a higher sensitivity to androgenic side effects such as acne and hair loss should be aware of this potential with Aromasin, though.
Other minor side effects that are listed for Aromasin by women using it as a medication include:
- Headache
- Dizziness
- Upset stomach
- Diarrhea
- Anxiety
- Hot Flashes
- Sweating
- Nausea
- Insomnia
- Depression
Again, these effects are relatively unlikely in male steroid users using this drug for estrogen control unless very high doses are taken or Aromasin is used for longer periods than is recommended or necessary for our needs of estrogen control.
Where to Buy Aromasin?
Suppose you have a regular supplier of AAS, SARMs, SERMs, or other ancillaries. In that case, you will likely find they sell Aromasin, as this is a popular AI (although rarely the most popular). As with most AIs, it can be challenging to get hold of pharmaceutical-grade products. Suppliers selling imported pharma-grade Aromasin are dicing with the law, so generally, you’ll need a word-of-mouth recommendation for a good supplier as some of the best won’t be widely advertising it.
Don’t fret, though: There’s always research chemical Aromasin available if you have no luck elsewhere, and these can be good quality.
Availability of Aromasin
Aromasin is relatively easy to find for sale at your favorite AAS or SARMs suppliers. Pharmaceutical grade, as always, is the ultimate prize if you can get it. Unlike most drugs, which are sold under multiple brand names, Aromasin is pretty much the only name you’ll find for Exemestane. Generics may exist in some countries, and these can often be cheaper than the name brand – however, you’d still need a prescription unless you can find generic Exemestane on the black market.
Underground labs can be a great source – if you find a good one! The best labs will provide a legitimate certificate of testing that confirms the ingredients and purity of the product so you know you are getting Exemestane. Research chemical Aromasin is a widely available option, and thanks to the legality (technically speaking) of selling and buying research chemicals online, most peptides and research chemical suppliers will stock Exemestane.
Is Aromasin legal?
Aromasin is only legal to buy with a valid doctor’s prescription. In the US and most other countries where Aromasin is a prescription-only drug, it’s illegal to sell, import, or manufacture Aromasin, and some suppliers have wound up with prison sentences.
However, you as a buyer are unlikely to run into legal issues because Aromasin is not a prohibited substance to possess or use – as long as you aren’t found with large quantities that could lead authorities to suspect you’re illegally selling Aromasin. These rules don’t apply in all countries, though! Many countries (India being one example) make Aromasin available as an easy over-the-counter purchase.
Typical pricing
Genuine branded Aromasin can be a costly pharmaceutical drug in the US, even with a prescription; some online retailers list 30x 25mg tablets at over $1000 without insurance.
Underground lab-manufactured Exemestane will be sold under different brand names (often using name variations of Aromasin). Expect to pay around $100 for 50x25mg tablets from quality labs that provide an authenticity certificate or lab result.
Research chemical grade Aromasin pricing is typically based on 30ml vials at 25mg/ml concentration. Expect to pay $45 to $60 per vial, but most suppliers will offer discounts for bulk buys.
Aromasin FAQs
Are Arimidex and Aromasin the same thing?
Both of these drugs are aromatase inhibitors, and both are designed to treat breast cancer in postmenopausal women. However, they are two different drugs, with Arimidex being a non-steroidal aromatase inhibitor and Aromasin being a steroidal AI, so there are clear differences between them.
It is known that steroidal AIs like Aromasin can bring about hormonal effects besides a lowering of estrogen that we don’t get with Arimidex. Further effects of the differences between these two types of AIs are still under investigation as far as their impact on medical users of the drug.
Can Aromasin cause liver damage?
The liver metabolizes Aromasin. While metabolites are known to be formed during this process, how potentially toxic they may be is still not fully understood. There have been rare cases of severe hepatotoxicity from the use of Aromasin in a minimal number of women using it long-term for cancer treatment. Still, the study states this is a small risk outweighed by the benefit of the drug[5].
It is unknown whether liver toxicity is a risk to steroid users making use of Aromasin. Still, the potential liver toxicity of some anabolic steroids should be of much greater concern.
Does Exemestane cause fatigue?
Fatigue, tiredness, or weakness can be reported by women using Aromasin for medical purposes, but this is not thought to be a significant issue for men using this drug during steroid use unless you’re in the process of a serious cutting phase where your diet is restricted. Aromasin might amplify any fatigue during this time.
Taking too high of a dosage of Aromasin can also bring about chronic fatigue, and if this does happen, lowering your dose should fix the problem quickly.
Does Aromasin affect cholesterol?
In a 12-month study focused on women using this drug for breast cancer, it was found that Aromasin has a neutral effect on cholesterol, so it did not raise or lower the levels overall[6]. This concerned total cholesterol and HDL levels (the good cholesterol type). Aromasin didn’t affect the levels of bad cholesterol (LDL). A benefit found in this study was that Aromasin lowered triglyceride levels, so less fat lipids were stored in the blood.
Despite this study, some other studies have found that Aromasin does, in fact, lower HDL levels in some women. This tells us that the effects may be highly individual between people, and these results may not necessarily have any bearing on men who use Aromasin over short periods while using anabolic steroids.
However, because many steroids hurt cholesterol, it’s possible that a potent aromatase inhibitor like Aromasin can amplify this negative effect on your cholesterol levels, making it critical to monitor cholesterol and take measures to maintain healthy cholesterol during this time by consuming a cholesterol-friendly diet.
Does Exemestane cause bone loss?
Aromatase inhibitors, including Aromasin, are known to reduce bone mineral density, which can lead to a higher risk of bone fractures and more serious diseases like osteoporosis.
Exemestane has been shown in studies to possibly result in less bone loss than other aromatase inhibitors because of its slightly different androgenic structure. However, these studies are on women who are at greater risk of bone loss from lower estrogen levels that Aromasin causes. There are no studies on men who use this drug to combat steroid side effects as to whether it can pose the same risk for bone loss or osteoporosis.
Final Thoughts
Aromasin is an aromatase inhibitor, so it lowers your entire estrogen levels, and gyno is caused by the excess estrogen when you’re using aromatizing steroids like testosterone and derivatives of testosterone like Dianabol (Dbol). Because Aromasin is so effective at lowering estrogen, possibly as low as 85%, it should work well to prevent or at least greatly minimize the risk of gyno.
Aromasin is a unique AI for two main reasons:
- It’s not likely to ruin your cholesterol like other AIs
- It’s capable of stimulating testosterone more effectively than other AIs
It is also known to work very well with Nolvadex and doesn’t come with the same incompatibility issues with that SERM as Letrozole or Arimidex. A complimentary PCT of Aromasin plus Nolvadex is a viable option, and quite simply – it is the only AI I would consider for PCT.
Ultimately, though, it’s the fact that Aromasin is a suicidal inhibitor that makes it my top AI choice. I like the lack of estrogen rebound and that I don’t have to mess around with tapering the dosage at the end. I stop when I want, then restart again if I start seeing those estrogen sides.
An AI is something you shouldn’t have to think about too much. Less planning is required with Aromasin, and let’s face it: enough planning goes into our AAS cycles.
We have some awesome aromatase inhibitors available, and I don’t claim Aromasin is the “best,” but it may be the best for YOUR needs on a specific cycle. I suggest always being flexible in the ancillaries you’re using on-cycle.
