What is MK-2866 (Ostarine)?
Ostarine (MK-2866, Enobosarm) is the most extensively characterised SARM — tissue-selective AR agonist with robust anabolic activity in muscle and bone, minimal androgenic effect in prostate. Standard SARM reference compound for AR selectivity profiling, muscle wasting models, and comparative SARM pharmacology. Research use only.
