Any drug can have side effects and steroids are no different. Side effects of Sustanon can come in various forms and are usually more prevalent for people who run continued length cycles or use more substantial doses.

Side effects from steroids can affect the cardiovascular system, estrogenic and androgenic.

When using anabolic/androgenic steroids, it is essential to understand the risks associated with the use and also how to minimise the chances of them occurring. 

It is important to note that not everyone will experience side effects from steroids. It is essential to know and understand the risk associated with them, though. 

We can break down the side effects of Sustanon into the following subjects;

  • Estrogenic side effects
  • Androgenic side effects
  • Cardiovascular side effects
  • Hepatotoxicity
  • Natural testosterone shutdown

Androgenic Side Effects

Testosterone is the main hormone in males and responsible for androgenic characteristics. With that in mind, it is important to note Sustanon can cause large breakouts of acne, especially on the back, oily skin and increased growth in body and facial hair. 

If male pattern baldness runs in your family it may make this condition onset quicker. People who suffer from prostate sensitivity or prostate cancer may see an increase in prostate growth. This can often return to normal after use. 

Estrogenic Side Effects

Sustanon is easily converted into estrogen. As such users can expect to suffer from side effects related to higher levels of estrogen in the body.

Added water weight, holding more body fat and gynecomastia are all unwanted side effects of Sustanon.

Anti-estrogens such as Arimidex or anastrozole work by reducing or stopping the conversion of testosterone to estrogen via the aromatase enzyme.

Cardiovascular Side Effects

Added water weight in short spaces of time and can result in added strain on the heart and organs.

Sustanon can affect cholesterol levels by reducing HDL or ‘good cholesterol’ and increasing LDL ‘bad cholesterol’. This shift, over time, can result in the hardening of the artery walls and higher levels of fat in the bloodstream leading to strokes, or heart attacks if left unchecked and untreated.

The increase in muscle mass and weight can also lead to higher blood pressure which can again, affect the heart and kidneys.

Running Sustanon can also affect your blood ‘thickness’. 

It is highly recommended for anyone thinking about running a cycle, or who has already run one to get blood tests done at least every three months. This not only allows you to know what is going in regards to your health but also make any necessary adjustments before starting.

Does Sustanon affect the liver?

Does Sustanon affect the liver?

Testosterone, in general, is metabolised by the liver. Adding exogenous testosterone to the body in moderate doses doesn’t really have too much of an impact on liver lipid levels.

It is important to note, though, high dose cycles or prolonged cycles could push liver markers beyond normal levels.

Natural Testosterone Shutdown 

Using any form of steroid will lead to the suppression of your natural test production. This often returns after the cycle has stopped. In rare cases or when users have been on cycle for prolonged periods, people can be shut down permanently or suffer from low testosterone levels for many years.

PCT ancillaries such as HCG can help keep the testes stimulated and producing natural testosterone. It is usually taken as a part of a PCT (post cycle therapy).

Benefits of using Sustanon

  • Increase in muscle density
