Testosterone Cycle

Testosterone is king when it comes to steroids. This hormone increases muscle size and strength. The majority of steroids you hear about are one form or another of testosterone, and usually synthetic derivatives of testosterone. And a testosterone only cycle is usually the first step taken for a new steroid user.

When going on a testosterone cycle you get to quickly find out how your body, and your performance and results, change as a result of boosting your testosterone to previously unseen levels. And yes, you will also get to find out what, if any, side effects you might be prone to.

From there you can tweak and adjust your cycles to get the best results. So let’s look into the popular testosterone cycles in more detail so you can make the best informed decisions about which direction you want to go in.

This guide has been broken down into the following sections:

What is Testosterone?

Testosterone Enanthate Structure
Testosterone Enanthate Structure

Testosterone is the main sex hormone in males which gives you all the characteristics that make you a man. Testosterone is mostly produced in the testicles, where it ramps up production beginning at puberty and continuing at full throttle until you’re around 30 years old; although this can vary between individuals.

In addition to being essential for life as a man, testosterone is also a natural anabolic steroid that promotes the building of muscle and strength – these are the anabolic properties of testosterone. The androgenic effects of testosterone are what give you a deep voice, facial and body hair, and all the things that differentiate you as a man to women.

Ester: what is it and why does it matter?

Understanding esters in organic chemistry can be difficult for the non-scientist, but you will soon come across several different esters of testosterone in the world of steroids and needless to say, you will want to know what it all means.

In basic terms, an ester is a synthetic derivative of testosterone. Different esters have a shifting around of atoms to form very slightly different compounds to the original organic compound.

Although there might only be one or two atoms different between one ester and another, this can be enough to change properties like how slow or fast a particular ester will be released into the body, and this is often the main difference between different esters and the one that may determine which one you’ll want to be using.

Most testosterone esters are suspended in oils like sesame oil or cottonseed oil. This provides a slower release of testosterone so it is not all used up by the body very quickly. The reason oils are used is because once an ester group has been added to testosterone, it becomes less soluble in water and more soluble in oil.

All the testosterone esters we come across are injectable and the dosage you use will depend on which ester it is and what your goals are for your overall steroid cycle.

The Most Popular Testosterone Esters: What’s the difference?

There are over 20 known esters of testosterone, but you will only come across a small number of these being available for use.

Most of these synthetic derivatives of testosterone have been developed for medical use to treat conditions like low or no testosterone in men. These compounds are able to provide a massive boost to testosterone levels, which is what makes them so attractive to us in the bodybuilding world.

The main testosterone esters you’ll see consistently talked about by bodybuilders and athletes are:

  • Cypionate (Depo-Testosterone, Andro Cyp)
  • Enanthate (Delatestryl, Xyosted)
  • Propionate (Testoviron)
  • Undecanoate (Andriol, Jatenzo, Aveed, Nebido)
  • Phenylpropionate (Testolent, Phenpropionate, Hydrocinnamate)

Testosterone cypionate and testosterone enanthate are considered to be very similar and even in the medical field these two esters are often interchangeable. The main difference between these esters is how slow or fast they’re able to be released into the body after an injections, and how long they elevate your testosterone levels.

Some esters will therefore need to be injected much more regularly than others if you are to maintain a consistent testosterone supply. This is why learning about the different esters, that I’ll cover in more detail below, is important.

The half life of each ester is one of the main differences between them.

CompoundActive Half-lifeDetection Time
Testosterone Cypionate 8-12 days3 months
Testosterone Enanthate 10.5 days3 months
Testosterone Propionate3-4.5 days2 weeks
Testosterone Suspension1 day1-2 days
Testosterone Phenylpropionate2-3 days1-3 days
Testosterone Undecanoate18-21 days3 months
Sustanon 25015-18 days3 months

Cypionate has an approximately 8 day half life, enanthate and propionate have a short elimination half life of about 4.5 days, undecanoate has a long half life of over 20 days, and phenylpropionate has a very short half life of less than three days.

Testosterone Cypionate Cycle

Testosterone Cypionate Structure
Testosterone Cypionate Structure

Testosterone Cypionate is another ester of the testosterone hormone and is one of then most widely used esters by bodybuilders and athletes. It has a half life of about 10 to 12 days so is a slower release steroid that is usually used in longer cycles of up to 14 weeks.

It has a longer half life than the otherwise very similar and equally popular Testosterone Enanthate that results in raised testosterone for about two weeks. Like all the testosterone esters, cypionate is highly effective on its own and can also be used with other types of steroids in a stacked cycle as it has high compatibility. It can take between four and six weeks to really start seeing the positive effects of a new testosterone cypionate cycle.

What is Testosterone Cypionate?

This testosterone steroid, like all the ester forms of testosterone we look at, is powerful when used both on its own and when stacked with other steroids. Testosterone stacks extremely well with almost every other steroid and can be used effectively in both cutting and bulking cycles.

Testosterone Cypionate can also be used as a supportive hormone compound where you are aiming to replace your testosterone to a normal level when using other steroids that suppress natural testosterone function.

With a relatively long half life, Testosterone Cypionate is usually injected about once per week depending on dosage; people who are using higher doses can opt for a twice weekly injection. Unlike a lot of other steroids, Testosterone Cypionate does not pose a risk for liver toxicity.

Testosterone Cypionate Benefits (Testosterone Cypionate Effects)

Testosterone Cypionate comes with the benefits and effects of all testosterone steroids; the ester attached to it simply controls the release time and in this case results in a slower release steroid that will suit people doing longer cycles. Some of the big benefits you will experience when using Cypionate at a higher dosage for performance and bodybuilding purposes include:

  • Testosterone Cypionate boosts protein synthesis, nitrogen retention, IGF-1 hormone, and keeps the body in a prime anabolic state to promote muscle growth, fat loss and, endurance muscle repair.
  • Testosterone Cypionate encourages the growth of lean muscle and the loss of fat making it ideal for a bulking and off season cycle.
  • It’s also ideal for cutting cycles as Cypionate helps retain lean muscle while fat being burnt, while also maintaining strength levels which can often otherwise suffer during heavy dieting phases.
  • Testosterone Cypionate enhances athletic and muscular performance with increased endurance and the ability to workout longer and harder without tiring as quickly as you normally would, ensuring faster progress towards your results.
  • Recovery is enhanced with an increase in red blood cells getting greater amounts of oxygen and nutrients to the muscles.

All of these benefits and effects are possible with Testosterone Cypionate, but your specific dosage and workout and diet routines will greatly determine just how powerful these effects will be. Your age and genetics also play a role in how this (and any other) steroid will affect you.

Your results are not necessarily going to be the same as the next guy at the gym using the exact same steroid cycle. Testosterone Cypionate provides the power to deliver exceptional results to those who are determined to use the steroid to its maximum potential.

Testosterone Cypionate Cycles

A Testosterone Cypionate cycle can be designed for cutting or bulking and this is a versatile steroid that stacks very well with almost any other steroid out there whether it is used as a primary compound or for testosterone support at lower doses.

Beginner Testosterone Cypionate Cycle

A 12 week cycle with a dosage of between 300mg and 500mg weekly and with no other steroids included makes this a safe, simple and easy to administer testosterone-only cycle for a beginner wanting to gain quality lean mass with minimal side effects.

Testosterone is considered the safest steroid for a beginner to start with until you can determine your own individual response, and then consider adding other steroids into a stack as intermediate and advanced users do.

Intermediate Testosterone Cypionate Cycle

If you’re at the intermediate stage then you will likely want to combine Testosterone Cypionate with other steroids in a stacked cycle, such as Deca Durabolin and Dianabol.

A typical cycle of this type would include Testosterone Cypionate at 500mg weekly and Deca at 400mg weekly for 12 weeks, with Dianabol providing a kickstart for the first 4 weeks only at 25mg daily. The primary benefits of this stack for intermediate users is for making big gains in strength and bulk while making use of three of the most popular and widely used steroids in a tried and proven stack cycle.

Advanced Testosterone Cypionate Cycle

Advanced users will often look at using Testosterone Cypionate as a supportive compound only while relying on much more powerful steroids to take on the role of the primary anabolic compound for muscle gains. An example advanced cycle of 12 weeks includes 100mg weekly of Testosterone Cypionate and 600mg per week of Trenbolone enanthate.

This cycle avoids the side effect of water retention because Testosterone Cypionate is taken at a low enough dose that aromatization can be avoided, and Trenbolone does not aromatize and convert to estrogen; therefore this advanced cycle comes with the added benefit of no estrogen related side effects.

Testosterone Cypionate Dosage

Beginner, Intermediate, and Advanced Testosterone Cypionate Dosage

Whatever your goals are, your Testosterone Cypionate can be tailored to meet them and this is a steroid that is considered one of the safest to use at bodybuilding doses where muscle gain is the main goal. Regardless of your experience level, the recommended dosage frequency is twice weekly injections to maximize and maintain your blood levels of the steroid.

This is a versatile steroid that can effectively be used from as low as 300mg weekly for beginners, right up to 1000mg per week for advanced users, with intermediate users often settling for 500mg to 700mg weekly for a very effective muscle growth dosage while still being able to control side effects.

While it might be tempting to increase the dosage to above 1000mg to increase gains, doing so also brings about heightened estrogen and androgenic side effects that are not worth the trade-off for the extra gains and dosing this high is not recommended.

Female Testosterone Cypionate Dosage

Very few females will opt to use Testosterone Cypionate due to the strong androgenic side effects that will occur and this is not a recommended steroid compound for women for that reason.

Side Effects from Testosterone Cypionate Cycle

As with all forms of testosterone, the side effects testosterone cypionate will greatly depend on your dosage. When using testosterone steroids at a performance enhancing level we are naturally going to see a greater risk of potential side effects than when using it as a testosterone replacement therapy.

For most men the side effects of Testosterone Cypionate are relatively easy to control with this well-tolerated steroid. As with all testosterone steroids, Testosterone Cypionate aromatizes so estrogen effects like gyno and water retention are possibilities Aromatase Inhibitor drugs can mitigate these side effects.

Testosterone Cypionate is an androgen hormone so these side effects can potentially occur including an increase in skin oil production leading to acne, head baldness and body hair growth. Testosterone Cypionate is not a recommended steroid for women to use due to its powerful androgenic effects.

Where Can I Buy Testosterone Cypionate?

Like all anabolic steroids, Testosterone Cypionate is illegal to purchase in the US and most other countries. Therefore, underground labs are generally the only place the steroid can be bought. Extra care should be taken when you’re looking to buy Testosterone Cypionate at higher doses because many underground laboratories underdose these products, while counterfeits of this particular ester are unfortunately common.

Testosterone Enanthate Cycle

Testosterone Enanthate Structure
Testosterone Enanthate Structure

Testosterone Enanthate is the most popular ester variant of the testosterone steroid. It has a half life of about 8 to 10 days and is a slow release testosterone steroid used in injectable form either for performance enhancement or as a testosterone replacement therapy.

Studies show significant increases in strength within 6 to 12 weeks when using testosterone enanthate, with bench press strength showing significant improvements in as little as three weeks of starting, as well as significant gains in body mass.

What is Testosterone Enanthate?

This form of testosterone bring with it the very same benefits that we see with other testosterone esters, with the main point of difference being the release rate of the hormone in the body once injected, and its half life.

Testosterone Enanthate is possibly the most widely used steroid as it is widely available, affordable and extremely effective for performance enhancement while bring highly versatile and effectively used with almost any other steroid in a stack for both bulking and cutting.

Testosterone Enanthate Benefits (Testosterone Enanthate Effects)

As with all the testosterone ester steroids you can expect excellent gains in muscle mass, improved recovery, reduction in body fat and the prevention of muscle breakdown with Testosterone Enanthate. Even though this is a relatively slow release ester, you can still expect to have your testosterone levels spike within the first 1 to 2 days of injecting Testosterone Enanthate as the ester slowly detaches and more testosterone is released into the bloodstream over time.

Results are achieved with this steroid by its positive effects on protein synthesis, nitrogen retention, boosting red blood cells, increasing the output of the highly anabolic Insulin-Like Growth Factor-1 (IGF-1) hormone, and reducing stress hormones that can bring about muscle catabolism.

The important thing to know about Testosterone Enanthate is that it is not a steroid that should be used strictly for bulking or cutting; instead, it is thought of as a very versatile steroid that can serve any purpose. It’s all about how you use it and what other compounds you might stack it with.

Testosterone Enanthate serves equally well as both a bulking or cutting steroid, but make no mistake – it has a very powerful ability to promote the growth of muscle tissue when used with a diet that supports these gains, and of course, a high quality, intensive workout regime.

In addition to the excellent performance and physique enhancements that Testosterone Enanthate is capable of helping you achieve, you can also expect to see the added benefits that come with using testosterone and maintaining a high level of the hormone; in particular your mental and sexual health should see improvements during this time.

Testosterone Enanthate Cycles

Testosterone Enanthate is effective both on its own in a cycle and when stacked with other anabolic compounds. It can perform exceptionally well as a primary anabolic compound but is also often used as a testosterone support to maintain testosterone levels when they are suppressed by the use of other steroids.

Beginner Testosterone Enanthate Cycle

A 12 week cycle dosed at 300mg to 500mg weekly provides an excellent introduction to steroids for the beginner by using the safest steroid in testosterone. Side effects should be easily mitigated at this dose and a beginner will gain an insight into the effects of Testosterone Enanthate on the body during this cycle.

Intermediate Testosterone Enanthate Cycle

Stepping up to the next level involves stacking other compounds with Testosterone Enanthate. A 12 week cycle consisting of Dianabol at 25mg weekly only for the first 4 weeks provides a boost to this bulking and strength stack. Spanning the entire 12 weeks is Testosterone Enanthate at 500mg weekly which is considered a very effective dose for any user level, and Deca Durabolin at 400mg per week.

Advanced Testosterone Enanthate Cycle

Even the most advanced users are best served with a 12 week cycle length, but in this case Testosterone Enanthate can be used as a testosterone support compound and not the primary anabolic compound. That role goes to the very powerful Trenbolone Enanthate which is an advanced level steroid only and never recommended for beginners.

600mg weekly of Tren and 100mg weekly of Testosterone Enanthate to support testosterone function provides a powerful cycle for either bulking, lean mass or cutting.

Testosterone Enanthate Dosage

Beginner, Intermediate, and Advanced Testosterone Enanthate Dosage

Regardless of your experience level, Testosterone Enanthate is usually injected twice per week to maintain the best blood levels of the hormone. Beginners will consider a dosage of between 300mg and 500mg which will provide exceptional anabolic effects.

Intermediate users can increase Testosterone Enanthate dosage up to 700mg weekly, with some advanced users increasing the dosage to 1000mg weekly as long as awareness of the much higher aromatizing side effects are taken into account.

Female Testosterone Enanthate Dosage

Testosterone Enanthate is not recommended for use by women for performance enhancement purposes due to the strong androgenic nature of this male hormone and its longer acting effects. Low doses as prescribed by a doctor are sometimes used to treat certain breast cancers in women.

Side Effects from Testosterone Enanthate Cycle

Compared with other steroid compounds, Testosterone enanthate can be thought to have only mild side effects risks as is the case with other testosterone esters. This is a hormone that the male body is naturally used to and it is just the higher dose for bodybuilding and performance purposes that introduce possible adverse effects as the effect of testosterone in the body is amplified. Testosterone naturally aromatizes at a relatively mild level compared with other steroids, and this is where we see the side effects developing as a result of estrogen conversion.

The higher the dosage, the greater the estrogen related effects will be. Individual reactions to the steroid will also vary which is why beginners should always use Testosterone Enanthate as a sole compound in a cycle to gauge side effects. Potential side effect risks include all the familiar adverse effects such as possible hair loss and acne, gyno, and in some people nausea and headaches can occur.

Water retention, when left to advance, can lead to high blood pressure and this is the more serious aspect of side effects you need to think about. It will also cause your gains to not be as made of as much solid muscle as you’d like, and these mass gains can dissipate following a cycle if water retention is high – therefore controlling estrogen side effects when using Testosterone Enanthate at higher doses is important not only for your health but for your longer term results.

Some users report irritation at the injection site when using Testosterone Enanthate and this does not necessarily occur when using other esters like Testosterone Cypionate, but this should be considered an individual response with tolerance levels to injections varying widely between people.

Where Can I Buy Testosterone Enanthate?

Like all steroids, Testosterone Enanthate is not legal to purchase or use for performance enhancing purposes without a prescription in the United States. So buying this compound on the black market is the only way to get your hands on it, and this comes with the risks of quality assurance and contamination.

While human grade pharmaceutical quality is available, underground lab products are also commonly found online and these can vary in quality substantially. Expect pharma grade to cost a lot more than underground lab sourced Testosterone enanthate. 250mg/ml is the standard vial quantity of this steroid.

Testosterone Propionate Cycle

Testosterone Propionate Structure
Testosterone Propionate Structure

Testosterone Propionate is a testosterone ester steroid with the shortest half life of all the most commonly used testosterone esters, at just two to three days. It therefore requires more frequent injections than most other forms of testosterone to maintain blood levels of the steroid. This also makes it one of the faster acting testosterone esters as is released over a period of just a few days.

Often Testosterone propionate will be injected every day of a cycle. On the upside, if you need a quick decrease in testosterone concentration for testing purposes or because you’re experiencing adverse effects, this ester only takes a short time to leave the body once you stop injecting.

What is Testosterone Propionate?

This is a testosterone hormone with the propionic acid attached to it. When injected, the ester slowly detaches in a controlled release time and this is when the testosterone becomes active. This means that at its core, Testosterone Propionate is simply pure testosterone and therefore comes with the anabolic and androgenic rating of 100 and 100.

When used at a moderate dose, Testosterone Propionate can effectively remedy symptoms of low testosterone in men. When used at a higher dosage, powerful anabolic effects are possible as we will see below.

Testosterone Propionate is a powerful steroid in its own right and can provide exceptional results for bodybuilders and athletes when used alone. Like all forms of testosterone, it’s also easily and effectively stacked with just about any other steroid out there making it a highly compatible and versatile steroid for many different uses.

Testosterone Propionate Benefits (Testosterone Propionate Effects)

The benefits and effects of testosterone propionate are the same as you’ll get with all forms of testosterone, with the choice of ester mainly coming down to availability and your desired half life and how often you’re comfortable administering injections.

This in turn relates to how stable you can maintain your blood levels of the steroid, and testosterone propionate comes with some advantage in this regard because the more frequent injections you’ll be using (because of this ester’s short half life) ensure that your blood levels are maintained to the most optimal level.

Thanks to its excellent anabolic activity, Testosterone Propionate comes with numerous benefits that boost both performance and results. These include the most important areas of anabolic processes in the body:

Enhances protein synthesis

This gives you a massive improvement in recovery and the growth of muscle tissue, since this process is how proteins are built by cells. The more efficient protein synthesis is, the faster your muscles recover from intense workouts and the quicker the muscle is repaired and grown.

Improves nitrogen retention

This is a critical process to keeping your body in the best anabolic state possible. When nitrogen becomes imbalanced, the body can fall into a catabolic state where you start losing muscle; this is to be avoided at all costs and the retaining of nitrogen ensures that your nitrogen output is lower than your intake of nitrogen – this is the prime state to be in for muscle growth. The better that nitrogen is balanced, the quicker the muscles recover the and faster they grow.

Increases red blood cells

More oxygen and nutrients getting to the muscles with greater blood flow equals increased muscle endurance so you can workout harder and for longer. Recovery is also enhanced with a greater red blood cell count.

Boosts insulin growth hormone (IGF-1)

This anabolic hormone is vital for many aspects of your bodybuilding goals: it’s involved in mass gain, endurance, fat burning and also boosts protein synthesis which in turn directly contributes to recovery through the repair of muscle tissue.

Reduces stress hormones

In particular testosterone inhibits glucocorticoids. While these are important hormones in some ways such as for fighting inflammation, they can also promote wasting of the muscles and fat gain. Testosterone helps to stop glucocorticoid hormones from dominating so the body can retain a higher anabolic environment rather than a more catabolic one which can occur when glucocorticoids become too dominant. This is one of the most important yet little known or understood aspects of using testosterone steroids.

Other benefits of this testosterone ester are:

  • It delivers fast results and is quick to leave the body compared with other esters
  • Useful for cutting cycles and muscle gains
  • More ideal for beginners and females compared to more slower release esters

Testosterone Propionate Cycles

Beginner Testosterone Propionate Cycle

A beginner user taking this ester alone in an 8 week cycle at 100mg every 2 days is a recommended cycle. A maximum beginner cycle of 500mg weekly for a 10 week cycle provides a good introduction for the new steroid user with a balance between results and side effects.

Intermediate Testosterone Propionate Cycle

A 10 week cycle is also suitable for intermediate users but commonly at this level Testosterone Propionate will be stacked with other compounds like Deca-Durabolin and Dianabol. 500mg weekly of Testosterone Propionate, with Dianabol at 25mg daily for 10 weeks and Deca for the first four weeks only at 400mg weekly is an effective intermediate cycle.

Advanced Testosterone Propionate Cycle

Advanced users are more likely to use Testosterone Propionate as a hormone support compound to replace the suppression of natural testosterone while using more powerful steroids. This cycle makes use of the very powerful Tren Acetate as the primary anabolic compound at 400mg weekly and Testosterone Propionate for testosterone replacement at 100mg weekly.

Testosterone Propionate Dosage

Beginner, Intermediate, and Advanced Testosterone Propionate Dosage

Taking 50mg to 100mg everyday or every two days is a common dosing strategy for testosterone propionate. Intermediate and advanced users may look at using testosterone propionate for more than 8 weeks and up to 12 weeks, with daily injections of 75mg to 100mg while stacking this ester with other anabolic steroids, or 100-200mg if using this ester on a testosterone only cycle.

Female Testosterone Propionate Dosage

Testosterone Propionate is a strong male androgen hormone so is not often used by females due to the drastic side effects that can occur. However out of all the testosterone esters, if a female is to use one it is Testosterone Propionate due to its fast clearance from the body but only in very low doses of about 25mg weekly for no more than 8 weeks maximum.

Side Effects from Testosterone Propionate Cycle

The potential side effects of testosterone propionate are the same as any other form of testosterone. Using the steroid at very low doses is unlikely to cause side effects, particularly when the purpose is to achieve a dose that’s at replacement level for low testosterone.

When higher doses are used you do run the risk of some side effects and most of these are related to estrogenic activity. When estrogen levels rise too much because of aromatization, there’s the risk of water retention and gynecomastia.

When water retention is not addressed, this can lead to high blood pressure. Nausea and fever are other possible adverse reactions some people experience

Due to testosterone’s natural function as an androgenic hormone, you may also see some side effects of this nature such as acne and hair loss; but only those who are predisposed to these conditions are at risk, especially when it comes to hair loss.

Suppression of your natural testosterone production is an inevitable side effect of using testosterone propionate and for this reason a suitable post cycle therapy plan is required.

Where Can I Buy Testosterone Propionate?

This testosterone ester is easy to come by online and is also known to be one of the more affordable steroids. As with all steroids, the purchase, supply and use of testosterone propionate for performance enhancing purposes without a prescription is illegal in the USA and many other countries. When buying testosterone propionate, always ensure the supplier is reputable to avoid low quality and potentially dangerous products.

Testosterone Suspension Cycle

Testosterone Suspension is the most powerful and pure form of testosterone available. Being pure testosterone, it comes with a very short half life at as little as two hours and therefore requires regular injections to maintain blood levels and for this reason it is not as widely used as the more common ester forms of testosterone which can be injected much less frequently.

This form of testosterone is not an ester, but is a water based derivative of testosterone Esters are oil-based and the difference here is that testosterone suspension has a short half life with the downside of needing more regular injections to keep up your concentrations of the compound. But this comes with the major benefit that it is taken in rapidly by the muscles.

This is a potent and powerful type of testosterone and does have a popular following amongst some bodybuilders due to the fast results that are possible, but many others find that the injection schedule is not worth it. Testosterone suspension is generally not recommended for beginners for this reason.

What is Testosterone Suspension?

Unlike the other forms we’ve looked at, Suspension does not have an ester attached and so is simply testosterone on its own. Esterified forms of testosterone are formulated with an oil based solution, but Testosterone Suspension is water based and becomes active as soon as it enters your body as there is no ester to slow down the rate of release. This makes Testosterone Suspension a very fast acting steroid with rapid results from this very powerful and pure steroid.

Testosterone Suspension Benefits (Testosterone Suspension Effects)

As the more unique form of testosterone, Suspension comes with some additional benefits particularly relating to how fast it works due to the lack of ester and water base which allows the steroid to become active immediately. Fast gains in strength and lean muscle can be expected, as can quicker recovery times.

Testosterone Suspension works to rapidly create a positive nitrogen balance and speed up protein synthesis. With this very fast acting steroid you can expect to see noticeable gains within the first week, with maximum gains experienced at just week 4 of the cycle. This makes Testosterone Suspension a substantially faster acting testosterone steroid than the ester forms.

Testosterone Suspension Cycles

The very frequent injections required of this steroid make it one that few people will use for a full cycle, with 4 weeks being standard for most users and advanced users sometimes extending to six weeks combined with other steroids.

Beginner Testosterone Suspension Cycle

Beginners can make use of Testosterone Suspension as the only compound in a short cycle of 4 weeks at a dose of between 50mg and 100mg daily. This will provide fast acting results, although you must be aware of water retention during this time, and introduce the new user to regularly injecting.

Intermediate Testosterone Suspension Cycle

Combining Suspension with another testosterone ester like Testosterone Enanthate and other compounds like Deca-Durabolin is a standard intermediate cycle plan. This cycle would still run Testosterone Suspension for 4 weeks at anywhere between 350mg and 700mg weekly. The other 2 compounds can be used for 12 weeks with Deca at 400mg weekly and 500mg per week of Testosterone Enanthate. In this cycle Testosterone Suspension provides a powerful kickstart to the results.

Advanced Testosterone Suspension Cycle

A powerful advanced 6 week bulking stack making use of Testosterone Suspension at 100mg to 200mg daily for the whole cycle combined with Dianabol at 25mg daily and Winstrol at 350mg per week for extra muscle hardening.

Testosterone Suspension Dosage

Most beginner users are unlikely to consider using Testosterone Suspension if for no other reason than the discomfort in committing to such regular and potentially painful injections. Even intermediate users may shy away from this steroid for these reasons, so it is often considered an advanced level steroid only.

Beginner, Intermediate, and Advanced Testosterone Suspension Dosage

If a beginner does decide to take on Testosterone Suspension, a dose of 100mg every two days is possible even though best results are always going to be achieved with daily injections. Intermediate users will need to commit to daily injections of between 50mg and 100mg each day. The most advanced users will inject up to 200mg per day and those who know exactly what they’re doing will often inject more than once daily to get the best results from this rapid acting steroid.

Female Testosterone Suspension Dosage

Testosterone Suspension is not a steroid that is ever recommended for use by females due to its exceptionally fast working nature and very high risk of androgenic effects; so there is no dosage recommendations for women to use this form of testosterone for performance enhancing purposes.

Side Effects from Testosterone Suspension Cycle

Estrogen related side effects are possibly with Testosterone Suspension and the higher the dosage, the greater the chance of these side effects. They can also come on quicker than with other forms of testosterone due to the fast acting nature of Suspension.

Water retention, blood pressure, and gyno are all possible estrogenic side effects that some people might experience. Androgenic effects are also a risk, including oily skin and acne, and hair loss in those predisposed to male pattern baldness. Other possible side effects include irritation at injection site as requires more regular injections.

Where Can I Buy Testosterone Suspension?

This form is mostly available as a veterinary drug where it is made as a short acting androgenic steroid for horses and dogs. Otherwise it is available only from underground labs where quality can vary widely, and potential contamination and low quality manufacturing can pose risks so due diligence is required if you choose to go that route with your purchase of Testosterone Suspension.

Testosterone Undecanoate Cycle

Testosterone Undecanoate Structure
Testosterone Undecanoate Structure

This is a very long duration ester, taking anywhere from one to three weeks to release. Testosterone undecanoate has been developed in capsule form as well as an injectable, but the oral form is not widely available and in some places, even the injectable form can be difficult to locate. Test undecanoate has the longest half life of all the most well known testosterone esters.

Test Undecanoate Benefits

  • Gain muscle and strength
  • Lose fat more easily
  • Very long half life so can require less frequent injections
  • Boosts protein synthesis and nitrogen retention

Possible Side Effects

  • Signs of masculinization like increased hair and lowered voice
  • Acne
  • Hypertension
  • Increased libido
  • Gyno
  • Water retention

Test Undecanoate Dosing and Cycles

As a less frequent injection due to its longer half life, this ester can be injected as infrequently as once every six weeks on a 1000mg dosage.

Testosterone Phenylpropionate Cycle

Testosterone Phenpropionate Structure
Testosterone Phenpropionate Structure

This is a short to medium acting ester with a one to three week release time and a three month detection time, for those concerned about testing.

Testosterone phenylpropionate is not widely used as a single ester amongst bodybuilders and is one of the less common ones you will come across. It’s more notable for its inclusion in Sustanon 250 (see below in this guide).

Test Phenylpropionate Benefits

  • Increased muscle mass and fat loss
  • Energy and endurance increase
  • Stacks well with other steroid compounds

Possible Side Effects

  • Androgenic side effects such as acne, gyno, changes in sex drive
  • Mood swings or aggressiveness

Test Phenylpropionate Dosing and Cycles

Two to three times weekly injections is the most common schedule ranging anywhere from 300mg to 3000mg per week depending on your experience level, goals, tolerance and control of side effects, and if you’re stacking Testosterone phenylpropionate with anything else.

Sustanon 250 Cycle

This is a combined blend of multiple esters with Sustanon being the brand name of this injectable testosterone. There are a total of four testosterone esters in this solution: propionate, phenylpropionate, isocaproate and decanoate. This is a group of both slow and fast acting esters with varying half lives, providing the benefits of all four in the one injection. Medically it is used in testosterone replacement therapy for men with low or no natural testosterone.

Sustanon 250 Benefits

Sustanon 250 Dosing and Cycles

Although the dosage for medical use of Sustanon 250 is 250mg every three weeks, bodybuilder users consume a wide range of dosages starting from 300mg weekly for a beginner up to 1000mg weekly. However, such extremely high doses come with a substantially greater risk of serious side effects.

A reasonable dosage for any level of user of Sustanon 250 is considered to be in the 500-750mg weekly range. If using Sustanon 250 not as the primary anabolic steroid in a stacked steroid cycle, but rather as a testosterone maintenance compound during a steroid cycle, a dosage of 100mg weekly is considered sufficient for this purpose.

A cycle of 10 to 12 weeks is required for Sustanon 250 due to most of the esters being longer, resulting in a longer half life and slower release rate.

For informational purposes, here are some ideas for Sustanon 250 cycles and stacks:

Sustanon 250 only cycle

  • Week 1-12: 500mg weekly of Sustanon 250
  • Week 13-15: Take nothing to clear your body
  • Week 16-18: PCT (Clomid, Nolvadex and/or AI)

Sustanon 250 Mass Cycle

  • Week 1-6: 500mg weekly of Sustanon, 400mg weekly of Deca-Durabolin, 40mg daily of Dianabol
  • Week 7-12: 500mg weekly of Sustanon, 400mg weekly of Deca-Durabolin
  • Week 13-15: Take nothing to clear your body
  • Week 16-18: PCT (Clomid, Nolvadex and/or AI)

Sustanon 250 and Trenbolone Cycle

  • Week 1-12: 500mg weekly of Sustanon, 500mg weekly of Trenbolone
  • Week 13-15: Take nothing (clear your body)
  • Week 16-18: PCT (Clomid, Nolvadex and/or AI)

Side Effects From Testosterone Cycle

The potential side effects with a testosterone cycle remains largely the same regardless of which ester or esters you are using. Often there is only an atom or two difference between esters, making little difference to their effects but mainly changing their uptake properties.

Testosterone is well known for its androgenic side effects due to the conversion of testosterone to estrogen, which is why the use of anti-estrogens like SERMs or aromatase inhibitors is important so you can ward off the negative effects like acne, hair loss, aggressiveness and of course the dreaded gynecomastia.

These are all common side effects with the use of testosterone steroids and it is up to the user to formulate a cycle that balances the powerful positive effects of testosterone against the negatives. Each individual will react differently which is why what works for your best buddy might not necessarily be the right method for you to follow.

Some people are more prone to side effects than others, but with standard dosages most guys can tolerate testosterone well provided essential post cycle therapy is also carried out.


Gyno is the worst nightmare of any male steroid user. This is a swelling of the breast tissue which if left too long and too severe, can only be reversed by surgery. Proper PCT protocols with anti-aromatase drugs is critically important to keep gyno at bay as it comes about as a result from excess estrogen. First signs of gyno are often tingly, sore or puffy nipples.


Acne is a common possible side effect in guys who are prone to it. So if you had acne as a teen, your chances of having acne breakouts and oily skin from a testosterone cycle is going to be higher than someone who didn’t get acne as a teenager. Some people might experience a skin reaction or allergic reaction to the oil that a testosterone ester is suspended in – usually sesame seed or cottonseed oil.

Water Retention

Water retention is another side effect risk we commonly see with a testosterone cycle. This happens due to more subcutaneous fluids being present, and quickly sees you losing muscle definition in return for an undesirable bloated appearance. Preventing and reversing water retention is clearly a high priority for anyone taking testosterone.

Testosterone in Every Cycle

Without testosterone we wouldn’t have anabolic steroids and we can consider testosterone to be the most important steroid of all. Testosterone stacks well with virtually every other steroid and can also be used alone in a cycle with great benefit.

There are two reasons we use testosterone in a steroid cycle: either as a primary anabolic compound to directly contribute to muscle gains and other benefits as a central part of the cycle, or as a supportive compound to act as a testosterone replacement which is needed as a result of your normal testosterone production being suppressed during a steroid cycle at varying degrees depending which compounds you’re using.

In the case of the latter, the dose of testosterone is considerably lower and at just enough to maintain a healthy level of this critical male androgen hormone during your cycle. Let’s dig deeper into why the inclusion testosterone in every steroid cycle is so important.

The Importance of Testosterone Inclusion in Every Cycle

When we talk about including testosterone in a steroid cycle, it’s referred to as exogenous testosterone. That is, an external synthetic testosterone source in the form of one of the testosterone ester compounds above (although there are many others as well, but these are the most commonly used esters).

We must include this as either a primary or supportive compound in every steroid cycle because the steroids you’re taking send a signal to the testes that they no longer need to produce testosterone. All sensible steroid users will without question include testosterone in every cycle for this reason alone at the very least.

While using testosterone as a primary compound at a higher dose for its countless benefits for muscle growth, recovery and performance enhancement is hugely beneficial, if this is not desired then you can simply make use of testosterone at a lower supportive dosage that aims to maintain a functional level of the hormone while one or more other steroids in your cycle take on the primary anabolic role.

Although the dosage will vary depending on the make up of your cycle, an example of a supportive testosterone dosage is 100mg weekly, while using testosterone as a primary anabolic compound will see the dosage raised to 500mg weekly or higher.

Why Must Testosterone Be Included In Every Cycle?

There’s so much more to the testosterone hormone than just being important for muscle growth. In fact, that’s not going to be the main reason you must include testosterone in every cycle (although it can be a great benefit if you utilize the steroid in that way as well). As an adult male, you need testosterone to function, plain and simple.

When your steroid cycle is suppressing your natural testosterone production by shutting down testicular function, you must synthetically raise and maintain your T levels to avoid the downright horrendous effects that will otherwise occur, which you can read about below.

If testosterone is not included in every cycle, symptoms of low or no testosterone will happen not only while you’re using steroids, but after your cycle ends as well as it takes some time for natural production to start increasing again. Post cycle therapy is also a critical area that will contribute to getting your natural testosterone back on track after a steroid cycle.

Why Must Testosterone Be the Only Anabolic Steroid In a First Cycle?

Every single steroid compound comes with its own individual side effect risks and complications. While these can be similar across certain categories of steroids, how they affect you as an individual is entirely unpredictable – you simply will not know how your body will react to a steroid until you use it for the first time. This means that using more than one steroid in a cycle (i.e. stacking) will not allow you to determine which steroid is causing which side effects.

This can not only hamper your performance and results, but even more importantly can be downright dangerous when we start talking about side effects like high blood pressure and cholesterol. Reading about other people’s experiences with certain steroids on web forums and social media doesn’t prepare you for what YOU will experience with the same steroid. So by making use of one steroid at a time and getting a hold of which side effects you are prone to, and how severe they are, you can slowly put together your own safe and effective stacks in future.

And starting with testosterone as the only anabolic steroid in your first cycle lets you begin with the most important steroid of all which will test your body’s tolerance and reaction to steroids very quickly. After all, if you experience adverse effects in a basic testosterone only cycle then there is a higher chance of negative reactions to the many other steroids out there, many of which are derivatives of testosterone.

What Are The Risks of Leaving Testosterone Out of Every Cycle?

Leaving testosterone out of your steroid cycles brings almost certainty to the situation of very low to no testosterone in your body. Low or no testosterone brings severe health consequences to any man in all areas of life, including both the body and the mind. Leaving testosterone out of a steroid cycle and allowing your testosterone to drop to a very low level puts you at high risk of:

  • Loss of muscle, tone and reduced strength
  • Increase in stored body fat and difficult losing it
  • Depression and irritability
  • Erectile dysfunction and lowered or absent libido
  • Lack of energy and motivation

As you can see, low or no testosterone is a serious dilemma and one that steroid users need to avoid as best as possible by including testosterone in every cycle and also by implementing effective post cycle therapy protocols.

What Results Can I Expect Using Testosterone?

Testosterone is a highly powerful steroid that acts in multiple ways to increase lean muscle mass by increasing protein synthesis, decreased body fat, boosted endurance and athletic performance, and improve recovery times; amongst other benefits.

It also acts as an anti-catabolic that blocks hormones like cortisol and therefore helps prevent the breakdown of muscle tissue (muscle catabolism). Stronger bones and improved mental clarity, focus and energy are often additional benefits of testosterone. Increased cardio output and blood flow to the heart assist with athletic performance.

Here are the big benefits of using testosterone in a steroid cycle:

Muscle And Strength Gains

This is the main reason we want to use testosterone: it increases muscle mass and boost strength. By increasing the process of protein synthesis and blocking the effects of the stress hormone cortisol, testosterone is all about putting you into a prime anabolic state where you can’t help but gain muscle. Faster gains from strength training and faster recovery means you’re making gains significantly faster than could ever be possible without the use of steroids.

Faster Recovery

As I said above, you will see a noticeable improvement in your recovery time even after the heaviest, longest workouts because testosterone helps muscle tissue repair faster. This means you’re back in the gym at your next workout sooner, working those same muscles and building them up at a rate and to a size that you just couldn’t achieve without taking advantage of the power of testosterone steroids.

Fat Loss

With increased lean muscle comes a greater ability to burn fat and keep it off, creating a cut, lean and ripped physique. Although a testosterone only cycle is not generally used for hardcore cutting, it still plays a critical role in eliminating the storage of fat and loss of muscle that comes about as a result from having low testosterone.

Other additional benefits include better endurance, energy and stamina, higher libido, better bone mass thanks to increased red blood cell production.

Testosterone is hugely powerful, but your gains will only be as good as your workout regime and your diet. Steroids and the required post cycle therapy drugs are by no means cheap, so unless you’re totally committed to sticking to a highly disciplined and very intense workout program and a diet that supports your gains, then steroids will be of little benefit otherwise.

Typical Testosterone Cycle For A Beginner

Testosterone puts the body into a prime anabolic environment, so little wonder it’s a first choice for a beginner’s cycle especially when bulking up is the main goal.

Testosterone Only Cycle

A very simple beginner cycle is to make use of either testosterone cypionate or testosterone enanthate and run it for an 8 week cycle, following up with PCT such as Clomid. A simple pyramid style cycle sees you starting low, increasing the dose in the middle, then decreasing again. For example:

  • Week 1: 200mg
  • Week 2: 300mg
  • Week 3: 400mg
  • Week 4: 500mg
  • Week 5: 500mg
  • Week 6: 400mg
  • Week 7: 300mg
  • Week 8: 200mg
  • Week 9-10: Take nothing to clear your body
  • Week 11-12: PCT (Clomid, Nolvadex)

Low Dose Testosterone Cycle

Even a low dose of testosterone can provide a solid boost to performance and gains, and if you’re just starting out you might want to test the waters with the lowest most effective dosage. These so called mild cycles of around 250mg per week still provide benefits, while reducing the impact on side effects.

Going any lower than 250mg is unlikely to provide many benefits since you will only be at testosterone replacement levels by replacing your natural testosterone but not exceeding that level – in other words, a low dose cycle of 300mg weekly may provide the best balance between gaining benefits and minimizing side effects.

Another option is to use testosterone in a gel form as a first line treatment during a testosterone replacement therapy (TRT).

Regardless of what your testosterone cycle is, doing post cycle therapy is critical if you not only to maintain your hard earned gains from the cycle, but also get your natural hormone functionality back on track once the synthetic testosterone injections have stopped.

Typical Testosterone Cycle For Those With More Experience

A more advanced testosterone cycles will almost always involve stacking it with other types of steroids like Dianabol, as well as combining multiple testosterone esters into the one long cycle; often using one ester for half the cycle and switching to another for the second half of the cycle.

An example of an advanced testosterone enanthate and Dianabol 12 week bulking cycle would be:

  • Week 1-6: 500-750mg weekly of testosterone enanthate, 40mg daily of Dianabol
  • Week 7-12: 500-750mg weekly of testosterone enanthate
  • Week 15-19: PCT beginning at week 15 and running for four weeks.

Basic Cutting Cycle

  • Weeks 1-12: Testosterone Propionate, 30-50mg/every day
  • Weeks 1-12: Testosterone Enanthate or Testosterone Cypionate, 100-200mg, Every 3 (3.5) Days
  • Weeks 13: Nothing the first 2-3 days to allow the exogenous testosterone to clear your body. Strat your PCT on day 3 or day 4
  • Weeks 13-Til: Starting day 3 or 4 – Clomid 25mg/every day or 50mg/every other day or Nolvadex 20mg/every day
  • Throughout Cycle (or at least on hand): An Aromatase Inhibitor (AI) like Arimidex at 0.5mg/every 3 days or Aromasin up to 25mg/every day.
  • (Optional) For 6 Weeks: Winstrol (Winny), 40-80mg/every day,
  • (Optional) For 6 Weeks: Anavar (Var), 40-80mg/every day.

Advanced Cutting Cycle

  • Weeks 1-12: Trenbolone Acetate, 50-100mg/every day
  • Weeks 1-2: Clenbuterol, 80-120mcg (2-3 times/every day)
  • Weeks 1-12: Testosterone Propionate (or Testosterone Enanthate), 50mg/every day
  • Weeks 1-12: Arimidex, 0.5mg/every 3 days
  • Weeks 13-14: Take nothing (clear your body)
  • Week 15-18: PCT Clomid 25mg/every day or 50mg/every other day or Nolvadex 20mg/every day
  • On Hand Throughout Cycle: A Dopamine Agonist like Dostinex to reduce the amount of prolactin.

Basic Bulking Cycle

  • Weeks 1-15: Testosterone Enanthate or Cypionate, 250mg/every 3 (3.5) days
  • Weeks 16-17: Take nothing to clear your body
  • Weeks 18-Til: PCT Clomid 25mg/every day or 50mg/every other day or Nolvadex 20mg/every day
  • Throughout Cycle (or at least on hand): An Aromatase Inhibitor (AI) like Arimidex at 0.5mg/every 3 days or Aromasin up to 25mg/every day
  • (Optional) For 6 Weeks: Dianabol (Dbol), 30-60mg/every day,
  • (Optional) For 6 Weeks: Anadrol (Adrol), 50-100mg/every day.

Advanced Bulking Cycle

  • Weeks 1-12: Testosterone Enanthate or Cypionate , 250-300mg/every 3 (3.5) days
  • Weeks 1-10: Deca-Durabolin, 200-250mg/every 3 days
  • Weeks 13-14: Take nothing to clear your body
  • Throughout Cycle (or at least on hand): An Aromatase Inhibitor (AI) like Arimidex at 0.5mg/every 3 days or Aromasin up to 25mg/every day.

Testosterone Post Cycle Therapy

As with all AAS use, post cycle therapy after a testosterone cycle is critical. The timing of the beginning of your PCT will depend on which ester you’ve used and what its half life is.

For example, you can start PCT three days after the end of a propionate cycle, while waiting two weeks to start PCT after using enanthate. These steroids cause your natural testosterone production to shut down, so PCT is vital to get it kickstarted again not only for your health and to mitigate estrogenic side effects, but also to stop your body remaining in a catabolic state after a testosterone cycle where you’re at risk of losing gains.

PCT options include SERMs and aromatase inhibitors to block estrogen. A basic Clomid PCT protocol would run for four weeks at 50mg per day for the first two weeks and dropping to 25mg daily for the final two weeks of PCT. Please read my full Post Cycle Therapy (PCT) guide to fully understand what is required for a testosterone post cycle therapy.

Common Q&A Related To Testosterone

Are Anabolic Steroids And Testosterone The Same?

Testosterone is a male androgen hormone which is also often known as a steroid hormone or an anabolic steroid. Testosterone has both androgenic (male traits) and anabolic effects on the body like building and repairing muscle.

Increasing muscle mass is the main reason people use testosterone in the form of an anabolic steroid. Testosterone steroids are synthetic derivatives of the hormone with slight modifications to the original chemical composition of testosterone.

Do Steroid Injections Hurt?

Injecting testosterone can be painful, particularly for beginners who are not used to the feeling of intramuscular injections. The most common injection sites are large muscles like the butt, shoulder or thigh. However even long term steroid users can find the pain of injection the least pleasant part of using steroids.

Since most cycles require injecting at least twice weekly (with a notable exception being testosterone suspension which normally requires daily injections), learning to tolerate the pain and discomfort of intramuscular injections is a must if you want to be able to use these compounds.

Is Testosterone Bad For Your Liver?

The highest risk for liver disease when it comes to steroids comes from those which are taken orally due to the slower methods of clearing the liver. Increased risk to liver health can also come about when people combine multiple steroids and medications, or abuse the substances at high dosage levels over a long period of time.

Is A Testosterone Only Cycle The Best First Steroid Cycle?

It’s often recommended to go for a testosterone only cycle when you’re starting out because it brings about fast strength and mass gains and gives you the chance to see how your body reacts to having a greater amount of testosterone circulating.

Stacking multiple steroids when you’re a novice is going to confuse not only your results, but your side effects and the steps you need to take in post-cycle therapy. Keeping it simple for your first steroid cycle is ideal, and testosterone is the best way to do that.

Do Testosterone Esters Show Up In A Drug Test?

Different esters have a different detection time based on their half life and how long they take to clear the body to a low enough level to avoid detection. This can be anywhere from a few weeks to three months after your last injection. For example, Testosterone cypionate and enanthate have a detection time of three months. On the other hand, Propionate has a quick 2-3 weeks detection period.

What Are The Long Term Health Effects Of Using Testosterone?

It’s well know that long term use of any steroids can cause damage to your health, especially when you’ve been doing many years of heavy use. In the most extreme cases, failure of the kidney, liver or heart can occur resulting in death.

Other risks over the long term include mental health problems like depression, increased mood swings and rage, more severe acne and skin problems, baldness, gynecomastia requiring surgery, and shrinkage of the testicles. Abscess and other complications are injection sites are another risk factor in both the short and long term.

What Is A Testosterone Half Life?

The half life of a testosterone ester is simply the measure of how long it takes for your body to eliminate half the dose. This is important to know when it comes to planning your cycle and understanding the most effective timing of your injections so you experience the maximum benefits, while minimizing side effects as much as possible. Of course, if you also think you’ll be exposed to drug testing, it’s important to know the half life of what you’ve taken so you know how much remains in your body at any point in time.

My Conclusion and Recommendation

What do you think? Are you ready to start your Testosterone cycle? Buy Testosterone from my recommended source (the source I personally use). They sell the finest quality Testosterone in an oral form and ever since I have tried their products, I have been using them exclusively.

PS: If you aren’t sure what testosterone ester you should add to your cycle, leave a comment bellow and I will see if I can give you any ideas.

  1. I’m going to run a 6 or 8 week cycle using Sustanon250, Deca bull300, and DBol 50mg/ml all are injectables. My question is what are the recommended doses and how long to use them? Also can I load all 3 in the same syringe and does the dbol have to be daily or is it fine to load up with the other 2 and use with them for ex. 3 times a week for 6 to 8 weeks? I would prefer to use with the others rather than daily with the dbol. I’m fairly new with steroid stacks your input and guidance is and will be very much appreciated. Thank You

    1. I’ll run a 12-week cycle with 500mg/week of Testosterone, 400mg/week of Deca for the first 10 weeks, and 30-50mg/day of DBol for the first 6 weeks. Throughout the entire cycle 0.5mg/day Arimidex to combat estrogen side effects. And NO, I don’t recommend adding all of the above in the same syringe.
