MK-2866, also known as Ostarine is the most researched and most widely used SARM available. It was developed and researched as a potential therapeutic aid to prevent cancer-related muscle wasting .
MK-2866 (Ostarine) and Muscle
Ostarine binds selectively to androgen receptors in muscle, connective tissue, and bone while avoiding receptors in the hair and prostate. Androgen receptors are programmed to receive information about steroidal hormones like testosterone and DHT . By stimulating these receptors, Ostarine mimics the action of exogenous testosterone on muscles without the visible androgenic side effects of taking testosterone like hair loss or prostate growth. By 2007, Ostarine was in a Phase II clinical trial .
In 2011 a double-blind, placebo controlled phase II trial focusing on elderly men and postmenopausal women showed statistically significant improvements in lean body mass, connective tissue health, and physical function with no significant adverse effects typical to steroids. Subjects also did not display the type of bloating and oedema that is common with growth hormone or growth-hormone producing therapies .
Ostarine and Sports
Ostarine is banned from competitive sports but gained popularity with athletes quickly after it was developed. In 2013 cyclist Nikita Novikov tested positive , in 2015 Ethiopian Chatlu Beji tested positive , in 2016 Romanian-canadian professional boxer Lucian Bute , Russian heavyweight boxer Alexandre Povetkin , Austrian triathlete Lisa Marangon all tested positive for Ostarine. In 2017 American triathlete Beth Gerdes , UFC light heavyweight Tom Lawlor , and UFC fighter Tim Means all tested positive . And in 2019 MLB pitcher Frankie Montas and NFL’s Taylor Lewan all tested positive for Ostarine [11,12]. Athletes should not participate in clinical research with Ostarine.
