What is osterine?

Ostarine is a Selective Androgen Receptor Modulator (SARM) that is under investigation for its potential to increase muscle mass and strength while minimizing side effects commonly associated with anabolic steroids. It is also being studied for its potential to treat conditions such as muscle wasting, osteoporosis, and hypogonadism.

Ostarine, also known by its chemical name MK-2866, works by selectively targeting and activating androgen receptors in muscle and bone tissues, leading to increased protein synthesis and muscle growth. Unlike traditional anabolic steroids, ostarine does not convert to estrogen or dihydrotestosterone (DHT), reducing the risk of side effects such as gynecomastia and prostate enlargement.

However, ostarine is not approved for human use by the U.S. Food and Drug Administration (FDA) and is currently prohibited for use in professional sports. Its long-term effects on health and safety are still being studied, and there is concern over its potential abuse in athletic competition.
