What is MK-2866 (Ostarine)?

• Ostarine, or Buy Hyperlean MK2866 Online (Enobosarm), is a selective androgen receptor modulator (SARM) originally developed to treat muscle wasting and osteoporosis. It binds to androgen receptors in muscle and bone—promoting anabolic effects—while minimizing targeting other tissues like the prostate.
