XStreamForce SARMs – YK11 is quite possibly one of the most powerful SARMs on the market today, due to its unique nature as both a SARM and a myostatin inhibitor.

Not only is YK11 a SARM, which will help promote lean muscle growth, but it also inhibits myostatin, which unlocks your natural bodybuilding potential.

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. While there isn’t much clinical evidence regarding YK11, anecdotal evidence suggests it’s an incredibly potent muscle building agent. In fact, as we’ll explore soon, lab rats which were given YK11 as treatment experienced absolutely mind-boggling muscle growth and results.
