YK-11, although recognized as a SARM, is a myostatin inhibitor. Myostine increases the expression of follistatin, which stops the release myostatin. Myostatin is a hormone that is your body’s choke on growth and development. When there’s lack of myostatin, there’s increased growth in muscle and strength.

YK-11 Myostine was discovered by Japanese scientists in 2011. It’s also a 5-α-dihydrotestosterone (DHT) derivative that has a unique molecular structure. Although it has SARM qualities, the compound features a steroidal backbone.

Because the compound is relatively new, researchers need further studies and clinical trials to identify YK-11’s category fully.

Research studies and human trials

The only research done on YK-11 are on cell samples, and there’s no administration of YK-11 on live organisms.

Researchers, however, did observe that application of YK-11 in cell samples resulted in muscle fiber production.

Clinical tests using bone cells from a mouse also gave the result of an increase in bone cells as well as mineralization.

YK-11 Side Effects

Currently, there are no published human and animal studies of YK-11. There’s no conclusive data on the long-term effects of YK-11.

Some researchers do note dose-dependent side effects. Taking YK-11 on high doses will result in a stronger intensity of sides. Professional researchers report joint pain and aggression while taking YK-11. There’s also the possibility of liver toxicity. Those who experiment with YK-11 observe suppression. PCT is highly recommended when you’re done with your research of YK-11.
