Like Many SARMs, YK11 side effects are minimal when compared to anabolic steroids.

What does YK11 do?

1. Inhibits myostatin
2. Increase muscle building
3. Improves muscle mass & recovery
4. Faster muscle growth than any SARM
5. No Hepatoxicity ( No Liver toxicity)
6. No estrogen effects

Is YK11 SARM or Steroid?

Studies confirm that muscle cells exposed to 500 nmol of YK-11 become more anabolic than DHT alone at the same dose.

YK11 SARM causes an increase in Myf5, MyoD, and myogenin synthesis of Follistatin.

These growth factors are signaling proteins that stimulate muscle growth.

YK-11 causes muscle cells to release Follistatin (a myostatin inhibitor) which is a potent anabolic hormone.

Grow beyond your genetic potential.

YK11 Results

YK11 half-life through urine elimination studies.

While unconjugated metabolites disappeared within 24 hours post‐administration, both glucuronidated and sulfated metabolites were traceable for more than 48 hours.

YK 11 is a synthetic steroidal selective androgen receptor modulator (SARM). It is a gene-selective partial agonist of the androgen receptor (AR). The drug has anabolic activity in vitro in C2C12 myoblasts and greater potency than dihydrotestosterone (DHT).
