Sustanon: Usage, Benefits, Risks & Legal Alternatives

Sustanon box and injection vial.

What is Sustanon?

Sustanon 250, also known as Organon, contains the male hormone testosterone in the form of four different testosterone esters. The components of Sustanon include testosterone phenylpropionate, testosterone propionate, testosterone isocaproate, and testosterone decanoate.

Sustanon is sold in 100 mg/ml and 250 mg/ml concentrations and is used for testosterone replacement therapy in men with low testosterone levels. It is sold in glass ampoules, which may not be as convenient to use compared with other injectable androgens.

A 250mg dosage is comprised of the following amounts of testosterone esters:

  • 60mg Testosterone Phenylpropionate
  • 30mg Testosterone Propionate
  • 60mg Testosterone Isocaproate
  • 100mg Testosterone Decanoate

As the name Sustanon suggests, it is a sustained-release injectable drug. Once it is injected into a muscle, it produces effects that plateau after 12 days and lasts up to three weeks.

The standard treatment with Sustanon is to administer injections every three weeks. However, some people advocate for more frequent injection cycles to avoid dips in testosterone levels before each boost.

Is Sustanon 250 Legal?

In most countries, including the United States and the United Kingdom, Sustanon is a controlled substance and is classified as a Schedule III drug. This means that it is illegal to possess or use Sustanon without a valid prescription from a licensed medical professional.

It is important to note that the laws regarding the use and possession of Sustanon and other controlled substances can vary by country and even by state or province. It is always best to consult with a licensed medical professional or a legal expert to understand the specific regulations in your area.


Sustanon produces many of the benefits characteristic of androgens, such as increased muscle mass and energy levels. It can counteract the effects of low testosterone in males, such as low energy, reduced sex drive, and low bone density.

Sustanon and similar androgens are sometimes used in adolescent boys as a treatment for delayed puberty. In this context, Sustanon induces growth in skeletal muscle, increased muscle mass, and deepening of the voice.

Side Effects

Sustanon 250 has estrogenic effects, which can lead to gynecomastia (enlargement of male breast tissue), water retention and bloating, increased blood pressure, fat gain, and decreased sperm levels. Sustanon also raises cholesterol levels and can increase the risk for prostate cancer and an enlarged prostate.

Consult your doctor or pharmacist if you have high calcium levels, are retaining water, or take medications that produce these effects. Sustanon can make these conditions worse.

In research trials, Sustanon caused elevated liver enzymes in rats, but it is unclear whether it poses a risk of liver damage or liver cancer in humans. Sustanon is toxic to infants and children under 3 years of age and should be kept away from children.

Because Sustanon is a testosterone replacement drug for men, women should not take Sustanon. Sustanon could interfere with menstruation and fertility and be harmful to a developing fetus.

Legal Sustanon Alternatives

Although a very potent anabolic steroid, sustanon is not safe to use and can place a major strain on your heart and other organs. ​Sustanon is very popular among bodybuilders due to its effects on muscle growth, size and strength gains, fat loss and recovery time.

But because of the sever risks and side effects associated with sustanon use, I strongly recommend using safer and legal alternatives that are available instead. There are some really good options in the form of legal sustanon 250 alternatives that provide most of the same benefits without all of the negative side effects.

Commonly referred to as “testosterone boosters”, these supplements are not only safe and effective but affordably priced as well. I’ve personally tested a large number of testosterone supplements over the years (a lot of which were completely worthless), but the ones that deliver the best results and I continue to keep in regular rotation are:

These supplements are ideal alternatives for anyone who wants to quickly get ripped, burn fat, or push their workout performance through the ceiling. These products also come with little-to-no side-effects or risks to your health, which is why they’ve become as popular as they have.

Sustanon has a significant medical role as a treatment for delayed puberty and low testosterone levels in males. The sustained release quality of Sustanon can reduce the need for frequent injections.

However, its lack of availability for medical treatment in the United States means that patients in the US will need to turn to other forms of testosterone for replacement therapy. As with other androgens and anabolic steroids, non-medical use to build muscle mass and strength in sports and bodybuilding is potentially dangerous, illegal, and forbidden by professional sports organizations.
