Testosterone propionate (often called “test prop”) is a short-acting, injectable anabolic-androgenic steroid and a form of testosterone replacement therapy. It is a synthetic version of the natural male hormone testosterone, used to treat conditions related to its deficiency.
Key Information
- Medical Use: Primarily for treating male hypogonadism (low testosterone levels), delayed puberty in boys, and some forms of breast cancer in women. It was the first testosterone ester widely used in medicine but has largely been replaced by longer-acting forms (like enanthate and cypionate) due to its need for frequent injections.
- Mechanism: As a prodrug of testosterone, it works by mimicking the effects of natural testosterone in the body, binding to androgen receptors to produce strong androgenic and moderate anabolic effects, such as increased muscle mass, bone density, and sex drive.
- Administration: It is administered via intramuscular injection, typically every 2-3 days, due to its relatively short half-life (around 2-4 days).
Non-Medical Use: It is also used illicitly by some athletes and bodybuilders to enhance physique and performance, which is a controlled substance in many countries.
