YK-11 Solution

YK-11 Historical Development:

YK-11 made its first appearance in the early 2010s when it was characterized by Japanese researcher Yuichiro Kanno. In initial studies, Kanno found that YK-11 selectively binds to androgen receptors, displaying SARM-like properties. The discovery raised interest as the compound was found to not only possess anabolic effects but also promote the release of follistatin, a protein that inhibits myostatin and is implicated in muscle growth and differentiation.

YK-11 Chemical Structure:

Chemically, YK-11 features a steroidal backbone, akin to that of classic androgenic hormones like testosterone. However, it also includes distinct modifications, such as a trifluoromethyl group and a carboxylic ester, which contribute to its unique binding affinity and selective modulation of the androgen receptor.

YK-11 Properties and Mechanism of Action:

YK-11, with its selective androgen receptor binding, exerts anabolic effects on muscle and bone tissues. Notably, its mechanism extends beyond that of a typical SARM. YK-11 also increases the levels of follistatin, which antagonizes myostatin, a protein that normally inhibits muscle cell growth and differentiation. Through the suppression of myostatin and the concurrent promotion of follistatin, YK-11 has potential to increase muscle growth.
