YK 11 Myostatin

yk 11

YK-11 attaches itself to the 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. It has been discovered that muscle cells produce more anabolic factors if exposed to 500 nmol (nanomoles)

YK-11 induces muscle cells to make more follistatin (more than DHT does) – a strong myostatin inhibitor. YK11 works through the androgen receptor. With that said,  YK-11 can be as good as testosterone in terms of muscle strengthening, but minus the detrimental side effects.


4 – 8 mg, 4 mg is often cited as the recommended moderate male dosage, and 4 mg is considered suitable, by many, for female use. 4 mg rarely causes significant testicular atrophy, and that remains to be seen even in higher doses. During post cycle therapy any symptoms of suppression are quickly alleviated, since the suppression of natural hormones is not as strong as with many anabolics.
