Exploring YK-11: The SARM Taking the Fitness World by Storm
YK-11 is a synthetic selective androgen receptor modulator (SARM) noted for its potential to enhance muscle growth and increase strength. It selectively binds to androgen receptors, aiming to minimize androgenic side effects associated with steroids. Promoting lean muscle gains possibly by increasing follistatin, a myostatin inhibitor, YK-11 has yet to undergo extensive clinical testing, raising safety concerns. Possible adverse effects include liver toxicity and hormonal imbalance, while its legal status varies, often being labeled as a research chemical rather than a supplement, stressing the need for further studies.
