YK11 is a synthetic steroidal selective androgen receptor modulator (SARM). It draws notable interest from bodybuilding communities due to its purported ability to stimulate significant gains in muscle size and strength, surpassing those of classic SARMs, while allegedly minimizing androgenic side effects.
YK11 is often praised in some circles for its potential to build muscle mass and enhance bone health. It is believed to achieve these effects by selectively binding to androgen receptors in muscle and bone tissue, thereby facilitating anabolic effects in these tissues specifically.
However, the precise mechanisms through which YK11 exerts its effects, as well as its safety profile, are not thoroughly understood due to a scarcity of scientific research, particularly in human subjects. Most information about YK11 comes from cell studies and animal research, limiting our understanding of its efficacy and safety in humans. It's imperative to note that YK11, like other SARMs, is not approved by regulatory bodies such as the U.S. Food and Drug Administration (FDA) for human use due to the insufficient data regarding its safety and efficacy.
Furthermore, YK11 is listed as a prohibited substance by the World Anti-Doping Agency (WADA), indicating that athletes subjected to anti-doping controls could face penalties if it is detected in their system.
