Ostarine, also known as enobosarm, MK-2866 or GTx-024, is the most clinically studied compound in the SARM class, having reached Phase 3 trials without approval. iMuscle manufactures it and Free Muscle stocks it in the Muscle Market range for research use by adults aged 18 and over.\u003c\/p\u003e\u003ch2\u003eAbout Ostarine (MK-2866)\u003c\/h2\u003e\u003cp\u003eOstarine is a non-steroidal selective androgen receptor modulator developed by GTx Inc. for muscle wasting and, later, for breast cancer.\u003c\/p\u003e\u003cp\u003eA 2011 Phase 2 trial in 120 healthy elderly men and postmenopausal women reported a placebo-adjusted increase in lean body mass of about 1.3 kg at the 3 mg dose over 12 weeks, alongside improved stair-climb performance, and also recorded falls in HDL cholesterol and modest suppression of testosterone (Dalton et al., 2011). A 2013 randomised Phase 2 trial in patients with cancer-related muscle wasting again found increases in lean body mass (Dobs et al., 2013), but the subsequent Phase 3 POWER trials did not meet their co-primary endpoints and enobosarm was not approved. It remains unlicensed as a medicine in every country.\u003c\/p\u003e\u003cp\u003eThe adverse findings carry as much weight as the lean mass figure. In the full 2011 report, HDL cholesterol fell with dose, by 27 per cent at the highest dose; in men, SHBG and total testosterone fell, though free testosterone did not change significantly; and eight participants had transient rises in the liver enzyme ALT, one of whom was withdrawn. Outside trials, physicians at the University of British Columbia described a previously healthy man in his early forties admitted with jaundice after two months of taking ostarine bought online, without medical supervision (Bedi et al., 2021). A liver biopsy showed moderate to severe cholestasis consistent with drug-induced liver injury, and his blood tests improved gradually over the following months. He had also been taking two prescribed medicines, and the report describes no analysis of the product. One case cannot show how often such injury occurs, and no long-term human data exist.\u003c\/p\u003e\u003cp\u003eThe findings above describe the compound in clinical research and case reports and are not claims about this listing.

A single 1 microgram amount could be detected for up to nine days, depending on whether ostarine itself or its glucuronide was the target, while hydroxylated metabolites gave considerably shorter windows.
