Ostarine MK-2866

What is MK-2866?

Ostarine MK-2866 is a non-steroidal Selective Androgen Receptor Modulator (SARM) with tissue-selective anabolic and androgenic properties. It is also known in the scientific literature as enbosarm, GTx-024, or S-22.

This connection was discovered in 1998 by James T. Dalton, Duane D. Miller, Karen A. Veverka, and their teams at Ohio State University, University of Tennessee, and GTx. The latter acquired the licensing rights and then transferred them to Merck & Co. for further development.

Research and properties

MK-2866 is one of the most extensively studied SARMs. In adult rats, the administration of Ostarine reduced the expression of leptin and adiponectin mRNA in fat cells. Researchers concluded that the effect is similar to that of testosterone on the androgen receptor, which may contribute to fat reduction (source).

"Another study demonstrated stimulation of bone growth. At a dose of 4 mg/kg, bone density increased, healing time improved, and levels of phosphorus and alkaline phosphatase rose (source)."

"Even at a low dosage of 0.04 mg/kg, the weight of the gastrocnemius muscle increased and the lipid profile improved due to a decrease in serum cholesterol."

Plant health and alternative androgen pathways

'In rats with induced osteoporosis, an increase in bone density was observed at moderate to high doses of Ostarine (source).'

A third study investigated mice without functioning androgen receptors. After the removal of testosterone-producing cells, muscle breakdown occurred. Treatment with MK-2866 led to muscle growth via an alternative pathway, independent of classical androgen receptors (source).
