Polvo YK11 CAS 431579-34-9

How It Works?

In direct comparison to to LGD-4033 as the reference for assay upon animal models of anabolism and androgenicity, YK-11 demonstrated higher efficacy withing anabolic parameters and lesser androgenicity at equivalent dosages.

YK11 attaches itself to the AR (androgen receptor), but only inducts methods that lead to the traditional side effects of androgens such as growth of body hair and prostate and enhanced aggression – to a restricted degree. Most SARMS have quite limited androgenic side effects, but frequently only quite few anabolic effects when likened to testosterone. YK11 induces muscle cells to make more follistatin (more than DHT does) – a strong myostatin inhibitor. YK11 works through the androgen receptor.

It induces muscle cells to make more follistatin which is a strong myostatin inhibitor. Myostatin (also known as growth differentiation factor, is a myokine (protein) produced by muscle cells that acts on muscle cells to inhibit myogenesis. Myogenesis is muscle cell growth and differentiation. Research through the years show that when you block myostatin, it allows for significantly more muscle mass. So in research myostatin inhibitors are researched to find cures for muscle diseases.
