{"title":"Ostarine (MK-2866)","description":"\u003cp\u003eOstarine, also known as MK-2866, enobosarm, GTx-024, S-22 and MK2866, is a non-steroidal selective androgen receptor modulator (SARM) of the aryl-propionamide family, developed by GTx Inc. It is the most extensively studied SARM in humans, having reached phase 3 trials for cancer-related muscle wasting. This page lists every brand of ostarine stocked at Free Muscle, compared on strength per capsule, capsules per pack and batch testing, and summarises what the clinical research reported, including where it fell short.\u003c\/p\u003e\n\u003ch2\u003eWhat is ostarine?\u003c\/h2\u003e\n\u003cp\u003eOstarine binds the androgen receptor (AR) and acts as an agonist with tissue-selective effects: in preclinical and clinical work it produced anabolic signalling in skeletal muscle and bone while having a much weaker effect on the prostate in men and on hair growth in women. It is not a steroid, is not aromatised to oestrogen and is not a substrate for 5-alpha-reductase. The aryl-propionamide scaffold from which it was derived was developed at the University of Tennessee and Ohio State University in the early 2000s, and the same chemical family gave rise to andarine (S-4) and S-23.\u003c\/p\u003e\n\u003cp\u003eGTx licensed the compound and developed it as enobosarm through phase 1, phase 2 and two phase 3 trials (the POWER programme) for muscle wasting in patients with non-small cell lung cancer, later pursuing it for stress urinary incontinence and AR-positive breast cancer. GTx reported in 2013 that the two phase 3 trials had not met their co-primary endpoints of lean body mass and physical function, and the drug was not approved. Clinical work has continued under a different sponsor: Veru Inc. has registered phase 2 studies of enobosarm in people taking GLP-1 receptor agonist medicines (ClinicalTrials.gov NCT06282458, 168 participants, completed August 2025, nothing posted on the registry by October 2026; NCT07446998, 239 participants, running since March 2026). None of this amounts to approval: ostarine holds no marketing authorisation from the MHRA, EMA, FDA or any other regulator and is not a prescription medicine anywhere.\u003c\/p\u003e\n\u003cp\u003eThe identifiers below, checked against PubChem in October 2026, are the values an ostarine certificate of analysis should agree with.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eIdentifier\u003c\/th\u003e\n\u003cth\u003eOstarine (enobosarm)\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCAS number\u003c\/td\u003e\n\u003ctd\u003e841205-47-8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMolecular formula\u003c\/td\u003e\n\u003ctd\u003eC19H14F3N3O3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMolecular weight\u003c\/td\u003e\n\u003ctd\u003e389.3 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePubChem CID\u003c\/td\u003e\n\u003ctd\u003e11326715\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWhat the published research reports\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePhase 2 trial in healthy elderly men and postmenopausal women (2011).\u003c\/strong\u003e Dalton and colleagues ran a 12-week double-blind, placebo-controlled trial of GTx-024 in 120 healthy elderly men over 60 and postmenopausal women.

In the 100 evaluable participants, median total lean body mass rose by 1.5 kg and 1.0 kg in the two active groups, while the placebo change was not significant. Serious adverse events, principally malignant progression, pneumonia and febrile neutropenia, occurred at similar rates across all groups and were not attributed to the study drug.

It was an open-label study without a placebo arm, funded by GTx, and its endpoints concerned the cancer rather than muscle. Drug-related grade 3 or 4 adverse events occurred in 8 and 16 per cent of patients in the two groups, most often raised liver transaminases, raised blood calcium (hypercalcaemia) and fatigue.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLiver injury reported outside trials (2021 to 2024).\u003c\/strong\u003e Liver injury has been described in case reports of people who took products containing ostarine: cholestatic injury resembling that seen with anabolic steroids (Bedi 2021); hepatocellular injury in a 31-year-old man three weeks after he started a supplement containing enobosarm, which improved once he stopped (Weinblatt 2022); and severe jaundice in a previously healthy 24-year-old man, with total bilirubin above 30 mg\/dL, treated with albumin dialysis, whose bilirubin was normal again only about six months after first intake (Mertens 2024). A 43-year-old man who reported taking ostarine together with cardarine for some days developed massive rhabdomyolysis and severe injury to liver cells, and was well again six weeks after admission (Kintz 2021). Case reports cannot show how often such injury occurs or, where two compounds were involved, which one caused it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnalysis of products sold online as SARMs (2017).\u003c\/strong\u003e Van Wagoner and colleagues bought 44 products marketed as SARMs online.

Ostarine was one of the three SARMs identified in the 2017 analysis above, in which the measured amount matched the label in only 41 per cent of products, so an independent certificate tied to the specific batch matters here.

It should name ostarine or enobosarm and report a result consistent with the formula C19H14F3N3O3 and the molecular weight of 389.3 in the table above; a value near 441.4 would point to andarine and one near 416.8 to S-23, its two closest relatives. Then check the purity or content per capsule, that the batch number matches your container, and that an independent laboratory is named with a test date.

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.
