German Pharmaceuticals YK-11 - 5mg

What it does?

YK-11  is a SARM 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?

SARM 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 SARMS 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 SARM’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.

Who should take it?

We do only advise YK-11 to men due to 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.

How to take it?  

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

Does it require Cycle Support?

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

Post Cycle

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.

    YK11 Review...

    It's not a bad product... been noticing similar side effects to pro hormones. Gained a little bit of size. Not much strength gained from this product. Great for adding to any kind of stack.
