Methenolone

Methenolone, also known as metenolone, is an anabolic-androgenic steroid (AAS). It is available in both oral and injectable forms, typically as methenolone acetate (oral) and methenolone enanthate (injectable). Methenolone was developed in the 1960s and was marketed under various brand names, including Primobolan and Nibal. It has been used medically for conditions such as muscle wasting diseases and osteoporosis.

Methenolone is a derivative of dihydrotestosterone (DHT). It is known for its anabolic properties with a relatively low androgenic rating. This means it is thought to promote muscle growth with fewer androgenic side effects compared to some other steroids. It is not aromatized, meaning it does not convert to estrogen in the body, thus avoiding estrogen-related side effects like gynecomastia and water retention.

In athletic contexts, methenolone has been used by some individuals to enhance muscle mass and strength. Its perceived lower risk of side effects has made it a subject of interest in performance enhancement. However, like all anabolic steroids, methenolone is a controlled substance in many countries and its non-medical use is prohibited by most sports organizations. Potential side effects can still occur and may include hair loss, acne, and cardiovascular strain. The legality and availability of methenolone vary significantly by region.
