Testosterone propionate

Testosterone Propionate is an ester of the primary male sex hormone, testosterone. It is one of the most commonly used anabolic steroids by athletes and bodybuilders. Testosterone propionate is often preferred for its easy control over the side effects and its quick action.

Chemical Structure[edit | edit source]

Testosterone propionate is a prodrug of testosterone and is an ester. It is synthesized by the reaction of testosterone with propionic acid. The esterification process makes the testosterone more lipophilic, which allows it to be released slowly into the bloodstream after injection.

Pharmacology[edit | edit source]

Testosterone propionate is a synthetic derivative of the endogenous androgen testosterone. It is designed to provide a fast yet extended release of testosterone. The propionate ester is suggested to develop a circulation peak within 24-36 hours after injection, and the testosterone hormone is released for up to a few days afterward.

Medical Uses[edit | edit source]

Testosterone propionate is used in medicine to treat males who have low or no testosterone production. It is also used to treat certain types of breast cancer in women.

Side Effects[edit | edit source]

Like all anabolic steroids, testosterone propionate has potential side effects. These can include acne, hair loss, increased body or facial hair, voice deepening, and changes in sexual desire. More serious side effects can include liver disease, mental/mood changes, and unusual tiredness.

Legal Status[edit | edit source]

In many countries, testosterone propionate is regulated as a controlled substance under the Anabolic Steroids Control Act. It is also listed in the World Anti-Doping Agency's list of prohibited substances.
