What is Ostarine (MK-2866)?
Ostarine (MK-2866, Enobosarm) is one of the most extensively studied SARMs. Binds the androgen receptor with high affinity and selectivity, producing anabolic effects in muscle and bone with minimal androgenic activity in prostate and other tissues. Well-characterised SARM reference compound for receptor selectivity research, muscle wasting models, and comparative SARM pharmacology. Research use only.
Research Applications
SARM Reference Compound
Most-studied SARM — reference standard for AR selectivity profiling and assay validation
Muscle Wasting & Sarcopenia
Lean mass preservation, nitrogen retention, cancer cachexia and age-related models
Bone Density Research
Osteoblast stimulation, BMD maintenance, osteoporosis prevention models
Minimal Androgenic Activity
Low prostate stimulation vs full AR agonists — selectivity ratio quantification
Comparative SARM Research
MK-2866 vs LGD-4033, RAD-140, S23 — potency, selectivity, suppression profiles
