MK-2866, also known as Ostarine or Enobosarm, is a nonsteroidal selective androgen receptor modulator (SARM). It has been widely studied for its anabolic effects on muscle and bone while minimizing androgenic activity in other tissues. Preclinical studies show MK-2866 enhances lean muscle mass, improves strength, and supports skeletal integrity, making it a key compound for musculoskeletal and metabolic research. Its oral bioavailability and favorable safety profile compared to traditional anabolic steroids have contributed to its extensive investigation in experimental models.
