What Is Ostarine (MK-2866)?

Ostarine, scientifically known as MK-2866, is a Selective Androgen Receptor Modulator designed to interact with androgen receptors in a targeted and receptor-specific manner. Its selectivity has made it one of the most studied SARMs, frequently referenced in research exploring:

  • androgen receptor modulation
