YK11 is a selective androgen receptor modulator (SARM), which activates AR without the N/C interaction.

In this study, we further investigated the mechanism by which YK11 induces myogenic differentiation of C2C12 cells. The induction of key myogenic regulatory factors (MRFs), such as myogenic differentiation factor (MyoD), myogenic factor 5 (Myf5) and myogenin, was more significant in the presence of YK11 than in the presence of DHT.YK11 treatment of C2C12 cells, but not DHT, induced the expression of follistatin (Fst), and the YK11-mediated myogenic differentiation was reversed by anti-Fst antibody.

Myogenic differentiation is in reference to the products ability to block myostatin. Myostatin inhibition has been a really popular movement since the ban of most prohormones as it looks to be a relatively unexplored area for muscle growth and fat loss. There are currently a lot of claims about mystatin inhibition, but not so much factual data on these products.

YK11 will have similar affects to DHT (possibly more potent) without the negatives of DHT.

What this means is that the product will most likely be suppressive and require a post cycle, but not cycle support. It also won’t have androgenic side affects like hair loss, acne, etc.

The increase in follistatin caused by YK11 will act as an antagonist to mystatin (it will block myostatin) as well as the anabolic growth properties of YK11.

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.

Kanno tested C2C12 muscle cells and not lab animals or humans. It has been discovered that muscle cells produce more anabolic factors if exposed to 500 nmol (nanomoles) YK11 than if you expose the same muscle cells to 500 nmol DHT.

YK11 induces muscle cells to make more follistatin (more than DHT does) – a strong myostatin inhibitor.

YK11 works through the androgen receptor. The YK11 research evidence shows that YK11 causes a larger increase in the synthesis of Myf5, MyoD and myogenin than DHT does. Myf5, MyoD and myogenin are signal proteins that induce muscles to grow.With that said, YK11 can be as good as testosterone in terms of muscle strengthening, but minus the detrimental side effects.YK11 shows a lot of promise as an apt anabolic SARM. With the muscle growth potential it brings, it’s as effective as anabolic steroids and prohormones without the unwanted side effects connected to the latter.The recommended dosage of yk 11 is 5-10 mgs/day.

Recommended maximum dose YK11 is require dosages of 2.0-5.0mg b.i.d. in males and 0.5mg-2mg b.i.d. in females to achieve optimal effects in humans for the noted indications.
