Ostarine (MK-2866) is a research compound classified as a Selective Androgen Receptor Modulator (SARM). It is designed to selectively bind to androgen receptors in muscle and bone tissues, promoting anabolic activity without the unwanted side effects typically associated with traditional anabolic steroids. Ostarine has been studied for its potential to support muscle preservation, improve lean body mass, and aid recovery from injuries, particularly in cases of muscle-wasting diseases or age-related muscle degeneration.
Due to its tissue-selective action and mild profile, Ostarine is commonly researched for its effects on body composition, strength maintenance, and musculoskeletal health.

Note: Ostarine (MK-2866) is a research chemical and is not approved for human consumption. For laboratory research use only.
