Sustanon is a powerful steroid made up of five different esters of testosterone combined into the one solution. Sus is a form of testosterone replacement therapy (TRT), it is designed to provide a sustained release of testosterone into the bloodstream over an extended period. This allows you to reap the benefits of the way each ester is consumed by the body with a mix of both fast acting and longer lasting esters all being administered in the one dosage. Sus is an injectable and is oil based.

Sustanon Mixture of the 5 testosterone esters:
Testosterone acetate
Testosterone propionate
Testosterone phenylpropionate
Testosterone cypionate
Testosterone decanoate

These esters make Sustanon one of the longest-lasting steroid compounds available today. It is an ideal compound for putting on size and increasing muscle strength. The propionate and phenylpropionate esters in this product are quickly utilized, releasing into circulation within the first four days. The remaining esters are much slower to release, staying active in the body for about two and three weeks.

As with all testosterone products, Sustanon is a strong anabolic with pronounced androgenic activity. It is mainly used as a bulking drug, providing good gains in strength and muscle mass. Although it does convert to estrogen, as is the nature of testosterone, this injectable is noted as being slightly more tolerable than cypionate or enanthate.

With Sustanon, blood levels of testosterone are building more slowly, so side effects do not set in as fast. For equal blood hormone levels however, testosterone will break down equally without regard to ester. Also correlating with estrogen, water retention would be noticeable with Sustanon, unless steps were taken to minimize estrogen.
Many individuals like to use a combination of Nolvadex & Proviron, while others use an anti-aromatase like Arimidex, Femara, or Aromasin, to help control estrogen related side effects.

For individuals with hypogonadism or low testosterone levels, Sustanon can help alleviate symptoms such as fatigue, low libido, mood swings. It may lead to improved overall well-being and quality of life.

Sustanon is the brand name of this injectable form of testosterone steroid. It has a medical use of treating men who have low levels of natural testosterone by acting as a testosterone replacement therapy (TRT).

There are 5 testosterone esters in Sustanon. An ester is an extra chemical addition added to the regular testosterone hormone which is then released in the body after injection. The timing and rate of release of each ester is what makes the four of these different: the testosterone itself is the same on each ester.
This makes Sustanon purely a testosterone compound and one what has had no alterations at all to the original testosterone hormone. Testosterone, as the natural male sex hormone, has an anabolic rating of 100 and an androgenic rating of 100 – Sustanon is pure testosterone. Other types of steroids skew these ratings one way or the other based on making modifications to testosterone or similar hormones.
So, while Sustanon as pure testosterone comes with many substantial benefits, it also comes with some potential side effects which we need to be aware of and learn how to combat them during a testosterone cycle as well as developing a post cycle therapy plan to recover afterwards. Below is an explanation on each oh the compounds in Sus for interest’s sake.

Testosterone Acetate
This is an exceptionally fast acting form of Trenbolone with a rapid half-life that quickly gets the compound taken up into the bloodstream. It has a half-life of just three days. Acetate includes massive boost to mass and strength, extremely fast results and excellent muscle hardening.

Testosterone Propionate
Test Prop is a fast-acting ester with a short half-life of around two or three days. This ester gets Sustanon working quickly to raise blood testosterone levels after administering your injection.

It ensures that Sustanon can get your testosterone levels raised within just 24 to 48 hours of your injection, providing the initial boost at the start while the other esters in Sustanon take their time to release over the next two to three weeks.

Testosterone Propionate injections when taken alone would need to be administered every day, so by making use of this ester in Sustanon you get the full benefit of Testosterone Propionate’s quick acting effects without having to worry about daily injections.
Testosterone Phenylpropionate
Test Phenylpropionate a relatively fast acting ester but one that can take anywhere from one to three weeks to fully release into the body ensuring it helps maintain a steady supply of testosterone as part of the Sustanon formula.

Testosterone Cypionate
Testosterone Cypionate is also medium acting ester with a half-life of about 4 days. This is an ester that is not available as an individual product but only consumed in formulas like Sustanon and other mixed testosterone ester preparations.

Testosterone Decanoate
Test Decanoate is a slow acting and long-lasting ester that keeps the effects of Sustanon active long after the injection. It has a long half-life of over 20 days.

Just like Cypionate, Testosterone Decanoate is generally not found as a single testosterone ester and instead only included in mixed ester solutions like Sustanon, making this one of the very few ways you can take advantage of the long-lasting benefits of the Testosterone Decanoate ester.

Dosage Instructions

250mg-650mg / Week

Beginner, Intermediate, and Advanced Sustanon 325 Dosage

An effective dose for men using Sustanon can start at 250mg weekly and go up to 2000mg weekly for advanced users. Beginners are always advised to start at the lowest effective dose and for some, this could even go as low as 300mg weekly. When combining it with other compounds, 500mg per week is almost always enough Sustanon to have a positive effect.

Advanced users are known to raise dosage anywhere between 1000mg and 2000mg weekly however this is rarely the case when other compounds are being used and such high doses by advanced users are almost always only done when Sustanon is being used alone. These higher doses will raise your risk of severe side effects substantially.




To get the most out of Sustanon a cycle length should be at least 10 weeks because of the slower release rate of one of the esters which allows the effects to be long lasting. A 10-week cycle should be considered a bare minimum however, with 12 to 14 weeks allowing the most benefits thanks to the longer half-life of this 5-ester combination.


Beginner Sustanon Cycle

Using Sustanon on its own or with one other compound for bulking is usually the choice of anyone starting out with Sustanon. A popular beginner cycle is to use the powerful bulking kickstart steroid Dianabol for the first 4 weeks with Sustanon also being used during that time and continuing with Sustanon for another 8 weeks to maintain the gains made with Dianabol.

Intermediate Sustanon Cycle

Intermediate users can add an extra compound to the above cycle, and this usually comes in the form of Deca-Durabolin. Dianabol provides the initial kick off for gains at the start of the cycle for four to six weeks, while Sustanon 325 and Deca are taken for the entire 12-week duration of the cycle.


Advanced Sustanon Cycle

Advanced users will often extend a Sustanon cycle out to 16 weeks to reap the full benefits of this long-lasting steroid. For an advanced bulking cycle making use of Sustanon, the same other compounds are often used and these Dianabol and Deca, with the difference between beginners and intermediate users being that advanced users will significantly increase the dosage of these other compounds, while still using Sustanon to retain a base testosterone supply over the entire 16-week cycle.

Sustanon Only Cycle

Beginners using Sustanon alone in a cycle can start from 325mg to 650mg weekly with 12 weeks being the minimum length for this cycle, while advanced users will choose to take to three times that dosage during a 12-week cycle.


Alternatively, when using Sustanon as base testosterone compound only during cycles that are more focused on other steroids, low doses can be effective below 200mg weekly which are run for as long as your regular steroid cycle is active.

Stacking Sustanon

Sustanon is well known for its compatibility for stacking with virtually any other type of anabolic steroid. Common stacks include Deca-Durabolin, Trenbolone and Dianabol particularly in the off season while cutting stacks make use of powerful compounds like Anavar, Winstrol and

Trenbolone where Sustanon can provide a base testosterone supply to help retain lean muscle during calorie deficit phases.


Your results from Sustanon will depend on several different factors: what you’re using it for (bulking, cutting or testosterone maintenance), any other steroid compounds you’re stacking it with in a cycle, your dosage and cycle length, your workout and diet routines, and how effective your post cycle therapy plan is. Genetics will also play a role.

With these aspects in mind, we can see how a one size fits all expectation of certain results does not exist, but it’s possible to gain some idea of what to expect when you use Sustanon.

For most guys it will be three or four weeks until you start seeing some noticeable gains, but again this will heavily depend on other steroids you’re using – particularly when using other compounds that have a higher anabolic rating and can help you pack on mass faster.

In these situations, you’ll probably find it difficult to attribute any particular result to Sustanon, but it will be helping your overall gains as part of your wider stack and making sure you are maintaining the level of testosterone needed for strength, muscle gain and fat loss.

Effect on Cycle

After injecting Sustanon, total plasma testosterone levels will start to increase, and you will reach the peak level of total testosterone at anywhere between the 24-to-48-hour mark after the injection. The main benefits of Sustanon are:

Boosts Protein Synthesis
Boosts protein synthesis resulting in a faster protein building process in the cells and as the building blocks of muscle, this means muscle repairs and grows faster.

Boosts Nitrogen Retention
Nitrogen retention is boosted by Sustanon. The muscle tissue contains a large amount of nitrogen and some of this is lost during intensive exercise.
By retaining as much nitrogen in the muscle tissue as possible, the body can remain in a more anabolic state for muscle growth while minimizing or removing the risk of muscle loss.

Nitrogen is also a critical component of amino acids which are what build protein. When more nitrogen is inputted or retained in the body compared the amount of nitrogen lost, the total available protein also increases.

Increases the Production and Release of Insulin-Like Growth Factor-1 (IGF-1)
Insulin-Like Growth Factor-1 (IGF-1) is important for the functioning of all cells. It facilitates protein synthesis and regulates the storage of fat so it can be efficiently used for energy production. IGF-1 positively impacts metabolism and helps with the increase of lean body mass and the loss of body fat.

IGF-1 is also important for bone health, nerve tissue regeneration and ligament strength. We can see how powerful IGF-1 alone is, but this is just one small aspect of the benefits that Sustanon 250 can provide as a pure source of testosterone.

Improves Athletic Performance
Performance enhancement is another reason people choose to use Sustanon. Improving athletic performance is to be expected when your testosterone levels are increased and optimized. This results in much better muscle endurance, taking your workouts to a new level. Noticeable improvements in recovery can also be expected as the full effects of testosterone kick in.

Sustanon has great benefits for both bulking and cutting goals. This is no surprise when we consider the powerful anabolic effects which are vital for both gaining muscle and for losing fat without the loss of muscle tissue. This gives Sustanon a place in both a bulking cycle and as part of a cutting cycle alongside other fat burning compounds.

Bulking Benefits
While not the most anabolic steroid out there with some others having a much higher anabolic rating, Sustanon can still be used in a steroid cycle where gaining strength and mass is the goal. When using Sustanon as the main bulking agent you can still expect to see quality gains and without the gaining of fat thanks to the way testosterone enhances the metabolic system to more efficiently burn fat.

Cutting Benefits
Using a form of testosterone during a cutting cycle is a popular strategy for anyone aiming to trim down and get ripped with the use of powerful fat loss steroids and one of the most important reasons is because of how Sustanon helps retain lean muscle tissue while you’re shredding fat.

Cutting requires a calorie restricted diet and intense cardiovascular activity which can easily result in a loss of muscle if the body falls into a catabolic state. Sustanon ensures you remain anabolic while cutting so not only do you improve body tone but also burn fat faster by retaining that muscle tissue.


Like all testosterone steroids, Sustanon has Strong androgenic effects and is also an aromatizing steroid which means it causes estrogenic side effects as well.

This means that the most dreaded side effects that steroid users face are at high risk of occurring when you use Sustanon including water retention and gynecomastia – these affect not only the appearance of your results but also potentially your health.

Learning how to control all these side effects is an important aspect of using Sustanon. Here are the main side effects to look out for when using Sustanon:

Estrogenic Side Effects
Sustanon (testosterone) is an aromatizing steroid which results in testosterone being converted into the female hormone estrogen.
Men require small amounts of estrogen for normal functioning, but the aromatizing process often results in a great imbalance between estrogen and testosterone, causing estrogen to rise beyond normal levels and this brings about familiar side effects. These are:

  • Gynecomastia – the growth of excess tissue on the breast area in males. If this issue is allowed to go on for too long, it can reach a stage where surgery is your only option to fix it.
  • Water retention and bloating – retaining too much fluid will give you a bloated look and mask some of the muscle gains you’re making or make it difficult or impossible to achieve a toned and refined look in a cutting cycle.
  • High blood pressure – water retention can cause blood pressure to rise simply because of the additional fluid being circulated those results in blood pressure increasing.

The higher your Sustanon dosage is, the more likely and more severe the estrogen related side effects will be as levels of that hormone rise further.

Androgenic Side Effects
The testosterone hormone has an even rating of anabolic to androgenic effect at 100 and 100 – or an anabolic:androgenic ratio of 1 – so we can expect the androgenic side effects to be as powerful as the anabolic benefits when using Sustanon as it is simply a testosterone combination steroid.
Besides the androgenic activity of testosterone itself, when that hormone is converted in DHT then a further increase in androgenic effects happen with DHT being a very powerful androgen compared with testosterone.

Not everyone will suffer with all or even any of these side effects as they can be heavily determined by your genetics, but it’s wise to be aware of the possibilities of androgen related side effects with Sustanon, including:

  • Oily skin and acne – increased sebum production can result in acne ranging from mild to severe, especially if you were an acne sufferer in your teens.
  • Baldness –hair loss ion males or a noticeable receding hairline can occur if you are genetically predisposed to baldness. This can be difficult or impossible to reverse and means you can experience hair loss sometimes several decades earlier than you were already going to thanks to your genetics.
  • Masculine effects in females – being a strong androgen, Sustanon is not recommended for females because of the virilization side effects which are highly likely. These include hair growth, voice deepening, clitoral enlargement, irregularities with menstruation and an overall major imbalance of having far too much testosterone in the female body which normally only has a very small amount.

So, what can you do about these side effects? The only way to manage them or try and prevent them completely in the case of estrogenic effects, is to make use of prescription drugs that were mostly developed to treat breast cancer in women either by blocking estrogen receptors or lowering overall estrogen.

Aromatase inhibitors (AI) are commonly used as are SERMs (Selective Estrogen Receptor Modulators). While SERMs are useful for tackling side effects like gyno specifically because of the way they target estrogen receptors in the breast tissue, AIs reduce overall estrogen levels and can therefore address all estrogenic related activity and as such have become the preferred option for combating these side effects.

Other side effects at the more serious end relate to Sustanon’s effects on cholesterol health. It can bring about a reduction in levels of good cholesterol (HDL), and this can get worse when you are using an aromatase inhibitor drug which is almost always the case. So, people with existing cholesterol issues need to strictly monitor levels and maintain a quality diet with omega-3 and other cholesterol friendly foods and implementing good amounts of cardio into your workouts.

Testosterone Suppression
Natural testosterone production is another unavoidable effect of using Sustanon because the body is receiving high amounts of testosterone from the steroid. This has no effect during your cycle but causes a drop in testosterone once Sustanon wears off at the end of the cycle. Here is where post cycle therapy is critical to trigger natural testosterone production again, without which you would be waiting many months for normal hormonal function to recover – resulting in severe low testosterone effects including loss of the gains you worked so hard for during your cycle.
