What is YK11?

YK11 belongs to a class of research chemicals known as SARMS, which were initially developed to help treat muscle wasting in cancer patients.

Selective androgen receptor modulators, or SARMs for short, have potent muscle building effects, and are generally well tolerated in studies.

While they were initially created to help cancer patients combat muscle wasting, bodybuilders quickly caught on, and realized that healthy individuals who took SARMs could experience steroid-like effects.
