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


Overview of Benefits & Effects

Before we take a deeper look at the clinical studies regarding YK11, first we’d like to offer a brief overview of the benefits and negative sides of this fascinating new research chemical.

    Extremely Powerful
    Rapidly Build Muscle
    Drastically Increase Strength
    Great Bulking Compound
    Rapid Fat Loss


    More Research Should Be Done
    Potential Side Effects for Some People
    Does Require A PCT (Post Cycle Therapy)

While there are no clinical human trials at the moment, both anecdotal evidence, and the existing research conducted on cells suggests that YK11 exerts an extremely powerful anabolic effect on muscle growth.
