Product Analysis
Product Data


YK-11 is a synthetic steroidal selective androgen receptor modulator. It is a gene-selective partial agonist of the androgen receptor and does not induce the physical interaction between the NTD/AF1 and LBD/AF2, which is required for full transactivation of the AR.

99% of products that claim to inhibit myostatin fail to do so effectively or at all. YK has the ability to increase follistatin compared to DHT or other synthetic steroids. Which would counteract the downsides mentioned above. 



50mg/ml within a 10ml vial.

Usually don’t write reviews. But this is the most authentic and potent yk-11 that I have ever researched. And I have researched about 5 other companies. Highly recommend. I am a lifelong customer.


Getting great results

I heard good reviews about yk11 in general, so I searched and compared different brands and types.
