The Myostatin Inhibitor that Promotes Lean Mass

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 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.

Guide to Supplementing YK-11

We do only advise YK-11 to men due to the affinity of anabolic ratio with regards to testosterone production, therefore, women would not be advised to take this compound.

We also advise that those under the age of 21 do not take this product as it can hinder natural testosterone production and may cause issues and unwanted side effects such as trouble reproducing and returning testosterone back to a normal level.

Although research on this is mixed, the general recommended a dosage of YK for many is 5-10mg a day, this is best to split into one-two dosages to ensure that the compound remains fully active in your system and the full benefits are achieved.

As the product is slightly methylated for it to be active it will evidentially not require any cycle support unless running for an excessive cycle length due to its strength, high doses/long cycles small cycle support is advised such as a milk thistle.

Post Cycle Therapy (PCT)

It is not mandatory to run a post cycle therapy with YK-11 if you run your cycle under 6 weeks at 1-2 caps a day however we would still recommend using a testosterone booster. If you stacked YK-11 with another compound and/or ran it for an extended period of time we recommend using an advanced hormonal recovery agent.
