GERMAN PHARMA YK-11
YK-11 is a S.A.R.M compound that causes increased activity at androgen cells, leading to increased protein synthesis.
Yk-11 is a key compound that has been researched for decreasing myostatin, which is the limiting factor of muscle growth, with myostatin suppressed they will find that building muscle will a lot easier.
Due to this property YK-11 is best for a bulking/muscle building cycle.
WHAT IS IT AND HOW DOES IT EFFECT YOU?
S.A.R.M is short for Selective androgen receptor modulator, this means that they regulate the amount of activity that take place in your androgen cell, which are the cells within the body responsible for nitrogen retention and protein synthesis.
When these S.A.R.M.S attach themselves to androgen receptors they allow for the maximum potential of that cell to be explored further than its current capability, enabling for better activity within the cell and an overall better performing musculoskeletal tissue.
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 S.A.R.M’s.
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.
