Sustanon is a is a combination of all testosterone esters; 1 ml each of: Testosterone propionate 30 mg, Testosterone phenylpropionate 60 mg, Testosterone isocaproate 60 mg and Testosterone decanoate 100 mg. It is a male sex hormone, which is produced in the testes and is responsible for regulating sexual activity and other metabolic activity in men.

Sustanon has three or four kinds of Testosterone, which have a very long-lasting effect when injected deep into the muscle. This is because the range of testosterone is released little by little from the muscle store over weeks. Because of this property, Sustanon is a form of testosterone hormone replacement therapy (HRT) for males with hypogonadism.

The frequency of injections also varies from individual to individual, depending upon your physical health, age and sensitivity.

These intramuscular injections can cause discomfort when you start them and it may continue for some hours after the injection. However, pain or soreness should end within a day or so. You may feel indigestion or nausea, but it is very rare.

Some common side effects include headaches, anxiety and mood changes. Although these are not serious side effects, if you experience any of them, you should consult your doctor. During the treatment of Sustanon, people may retain fluid and salt, which can result in increasing hypertension and heart conditions like angina or heart failure.
