MK-2866

Ostarine, also known as MK-2866, is a selective androgen receptor modulator (SARM) developed for the treatment of muscle-wasting diseases and osteoporosis. Unlike anabolic steroids, ostarine specifically targets androgen receptors in muscle and bone tissues, promoting muscle growth and bone density without significantly affecting other organs. It is popular among athletes and bodybuilders for its potential to increase muscle mass and strength.
