Wholesale Ostarine (MK-2866 / Enobosarm)
Bulk Powder, Capsules & White Label — B2B Supply from UK & EU
Ostarine (MK-2866), also known as Enobosarm, GTx-024, and S-22, is one of the most widely researched Selective Androgen Receptor Modulators (SARMs) in the world. Originally developed by GTx Inc. for the potential treatment of muscle wasting and osteoporosis, it remains among the most in-demand compounds in the wholesale SARMs market due to its well-characterised profile and broad research interest.
SARMs-Direct supplies wholesale Ostarine in raw powder and encapsulated formats to supplement brands, sports nutrition retailers, research institutions, white label operators, and distributors across Europe and internationally. All supply is strictly B2B and sold for research purposes only.

Research Context
Ostarine acts as a selective agonist of androgen receptors, binding preferentially to receptors in muscle and bone tissue while exhibiting minimal androgenic activity in other tissues. This selectivity has made it one of the most studied SARMs in clinical and preclinical settings.
Research interest has centred on its potential applications in muscle wasting conditions (including cancer cachexia and sarcopenia), bone density preservation, and metabolic function. It has been studied in multiple Phase I and Phase II clinical trials, making it one of the better-characterised compounds in the SARM class.
All products are supplied for research purposes only and are not intended for human or veterinary use.
