Sustanon Side Effects – Everything You Need To Know About The Most Popular Synthetic Testosterone
5 (100%) 1 vote

Sustanon (a.k.a. Sus) is arguably the most well-known form of synthetic testosterone across the globe. This steroid was originally created in the early 1970s, by a Dutch pharmaceutical company called Organon.

The rationale behind the production of Sus was to offer a more convenient approach to TRT (testosterone replacement therapy) as patients wouldn’t need to take separate forms of testosterone since Sustanon combines different kinds of esterified testosterone.

And logically, this anabolic steroid quickly gained fame in the realms of bodybuilding, due to its potency and the convenience of having multiple sources of synthetic T available in a single injection.

However, that doesn’t mean that there aren’t any drawbacks to using this steroid. That’s why in today’s post we’re going to examine the possible side effects associated with Sus and why it would be worth your while to opt for a safer (and just as effective) alternative.

So what does Sustanon consist of?

Sustanon is made up of four different types of esterized testosterone:

  • Testosterone Decanoate
  • Testosterone Phenylpropionate
  • Testosterone Isocaproate
  • Testosterone propionate

Although two separate versions of this anabolic steroid exist and their testosterone content and the associated concentrations of the active compounds differs:

  1. Sustanon 250 – The most widespread variation, this one provides a testosterone mixture of 250 milligrams/milliliter:
    – T. Decanoate – 100 milligrams
    – T. Phenylpropionate – 60 milligrams
    – T. Isocaproate – 60 milligrams
    – T. Propionate – 30 milligrams
  2. Sustanon 100 – The “lightweight” variant with an overall T content of 100 milligrams/milliliter:
    – T. Phenylpropionate – 40 milligrams
    – T. Isocaproate – 40 milligrams
    – T. Propionate – 20 milligrams

It should be noted that manufacturing of Sus 100 ceased back in 2009, so it’s safe to say that this variation of this steroid is 100% obsolete.

Also, keep in mind that because Sustanon is a blend of various forms of testosterone, each of them has a unique half-life (e.g. T propionate has an active half-life of four-and-a-half days). Subsequently, this means that Sustanon has a rather lengthy half-life – around 15 to 18 days.

What is the use of Sustanon?

The primary use of Sus is for treating hypogonadism. This is a rather unpleasant condition that’s characterized by low levels of the primary male hormone – testosterone.

That’s because the function of the gonads (testes) is impaired and they either produce insufficient amounts of T or the production of the male sex hormone is at a complete standstill. Sperm production may be affected as well.

And this is where Sustanon comes into play. Essentially, it replaces your own T production with an external (synthetic) source that’s supposed to compensate for the inadequate (or complete lack of) testosterone production by the gonads.

Here are a few intriguing facts related to Sustanon’s impact on T levels:

  • One 250 milligram-dose of this steroid has the potential to boost the overall plasma testosterone concentrations
  • Peak values of around 70 nanomole/liters are not uncommon
  • The maximum testosterone-boosting effects peak after roughly 24 to 48 hours after administering Sus

Sustanon 250 testosterone replacement therapy – how viable is it?

Apparently, doctors still use this drug and in fact – it’s one of the most popular choices when it comes to adequate TRT (testosterone replacement therapy).

It’s generally prescribed to patients with insufficient T levels, when that starts to cause certain complications associated with low testosterone levels, such as:

  • Lack of libido (sex drive)
  • Reduced sperm count
  • Lack of energy
  • Tiredness
  • Infertility
  • Osteoporosis (bone disease)

For this reason, physicians often prescribe good old Sus, which has been associated with:

  • Boosting libido
  • Improving sexual function
  • Treating ED (erectile dysfunction)
  • Increasing both muscle strength and muscle mass
  • Improving recovery

While this may seem very compelling and exciting, you shouldn’t forget that after all, Sustanon is a very powerful anabolic steroid. And as such, it also comes with a myriad of nasty adverse effects that you should be aware of before you even consider using Sus.

Sustanon side effects – how harmful can Sus actually be?

To put it briefly – very harmful! You see, while this anabolic steroid mimics the functions of regular testosterone created by the gonads, it’s still nothing but a synthetic, lab-made chemical that can be potentially detrimental to your health.

Even though side effects range from “harmless” complications such as hair loss and acne, some tend to be quite unforgiving such as gynecomastia (man boobs), increased blood pressure and even accelerating the growth of tiny prostate cancer cells that weren’t detected!

And since the original ‘side effects’ section of the Sus 250 leaflet is quite long, these are the most common unwanted effects associated with taking this drug:

  • Gynecomastia (enlarged breast tissue in men)
  • Nausea
  • Bloating (fluid retention)
  • Acne
  • Alterations of cholesterol levels
  • Liver function alterations
  • Depression
  • Hypertension (high blood pressure)
  • Increased (or reduced) sex drive
  • Roid rage (excessive aggression)

Quite clearly, there are more than enough reasons to stay away from Sustanon. Even if there are certain benefits associated with the injection of this lab-made testosterone, the cons by far outweigh the pros of this product.

Thankfully though, safer and just as potent alternatives do exist, such as Testo Max.


Sustanon might be the most effective synthetic testosterone blend to ever come out of a lab, but it’s still an anabolic steroid that carries plenty of nasty adverse effects that you’d want to avoid at all costs.

Wouldn’t it be great if we could just enjoy all of the amazing benefits of Sus, without worrying about developing man boobs or becoming too aggressive?

Well, that’s now possible and it’s called Testo Max – a cutting-edge product that’s designed to provide you with the most powerful testosterone-boosting ingredients on the market, including:

  • D-Aspartic Acid
  • Fenugreek extract
  • Panax Ginseng

This muscle-building and testosterone-optimizing powerhouse will give you rapid results in as soon as two weeks. Achieving an impressive and aesthetic physique, while also enjoying all the additional benefits of elevated testosterone levels has never been easier.
