YK11 Benefits:
YK-11 induces muscle cells to make more follistatin which is a strong myostatin inhibitor. Myostatin (also known as growth differentiation factor 8) as a myokine, a 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.
In addition to that, YK-11 is a bit leaner than LGD-4033, and is excellent for lean gains on par with testosterone. It produces lean, dry, easily kept gains in strength and muscle, and reductions in bodyfat.

How YK11 works?
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.
With that said, YK11 can be as good as testosterone in terms of muscle strengthening, but minus the detrimental side effects.
