It is one of the testosterone esters. Among the main modern manufacturers of propionate are BP (Balkan Pharmaceuticals), Magnus Pharmaceuticals, Swiss Remedies, Pharmacom

Historical background
Testosterone propionate was discovered in 1936 and was introduced for medical use in 1937. It was the first testosterone ester to be sold, and was the main form of testosterone used in medicine until 1960.

Action of testosterone propionate
Specifically initiates gene transcription, thereby changing the nitrogen balance in a positive direction.
Increases the level of insulin-like growth factor in muscles and liver
Causes proliferation of satellite cells in muscle tissue, due to which hyperplasia and muscle recovery occurs
It should be noted that all esters have the same mechanisms of action, the difference lies in the activity and predominant direction of action.

Effects

Increase in relief
Increase in strength indicators

Reduction in the risk of coronary heart disease and coronary heart disease
It has a short duration of action. Injections are usually performed every other day. This is one of the main disadvantages of using propionate, compared to its longer-lived analogs, for example, enanthate. The second main disadvantage is the higher cost compared to the same enanthate. It can be used both when working on mass and during the drying period.

Side effects of propionate

The most common complaint is pain, irritation and redness at the injection site, which is further aggravated by the need for a high frequency of their implementation. A pronounced increase in aggression

Side effects of testosterone propionate are related to the fact that it easily aromatizes and turns into estrogens and dihydrotestosterone, like any other testosterone ester, at high doses can cause:

Gynecomastia
Acne
Baldness of the scalp
Hirsutism (body hair growth)
Enlargement of the prostate (especially in the elderly)
Masculinization (in women)
The drug suppresses its own testosterone production, which is usually restored at the end of the course in 2-3 months. With long courses, it is necessary to administer gonadotropin at 500 IU, 1 time per week, starting from the 2nd. As practice shows, in moderate doses it does not affect the liver, kidneys, or any other internal organs. Not recommended for women, due to high androgenic activity.
