Product Description

YK-11

YK-11 suppresses Myostatin, which means muscles grow faster and larger without any side effects usually experienced with other Myostatin suppressing compounds like AAS or Prohormones.

One of the most frequently reported effects of YK-11 is that of increased pumps and muscle fullness, with many users claiming that this effect is even greater than when using oral AAS or Prohormones. YK-11’s ability to build muscle has been compared to testosterone, far exceeding other SARM’s. 

YK-11 has few side effects. Low level of suppression is possible in long term high dose use.

 YK-11 is dosed at 5mg per day for beginners and 10mg per day for advanced users. Cycle’s should run 4-6 weeks. Half-life is estimated at 6-10 hours. YK-11 can be stacked with other compounds for a big boost in muscle gaining potential. YK-11 is suited for cutting or bulking cycles and will excel in both uses.

 

The Science

 (17-alpha,20E) 17,20- [(1-methoxyethylidene)bis(oxy)] 3-oxo-19-norpregna-4,20-diene 21-carboxylic acid methyl ester

 YK-11 was first created as a novel compound in 2011 by Yuichiro Kanno of Toho University who confirmed in a study that this compound was in fact a SARM.

YK-11 is a partial androgen receptor agonist binding weakly at the androgen receptor and a potent myostatin inhibitor. Myostatin is a protein that slows muscle cells growing and dividing. YK-11 causes increased levels of another protein called Follistatin. Follistatin is an antagonist that suppresses the activity of Myostatin, leading to faster muscle growth and cell development in muscle tissue. 

YK-11 can increase Follistatin production more than DHT - which the strongest male hormone we naturally produce. Usually excess DHT would have the effect of causing baldness and prostate enlargement as side effects, but not with YK-11 - it doesn’t have this side effect at all due to it’s weak AR affinity. The methyl ester may cause very mild liver toxicity in long-term high dose use.
