Alphaform Labs YK-11

Take the brakes off muscle growth and get your gains into top gear with Alphaform Labs YK-11, a powerful selective androgen receptor modulator supplement (SARM) supplement scientifically proven to increase lean muscle mass with minimal side effects. YK-11 is a DHT derivative which acts as a partial agonist at androgen receptors whilst stimulating high levels of follistatin production - Follistatin inhibits myostatin, a naturally occurring protein which limits muscle growth. In short, supplementing with Alphaform Labs YK-11 is going to help you maximise your muscle building potential for results beyond training and nutrition alone.

Key Benefits

  • Androgen Agonist - Supplementing with Alphaform Labs YK-11, a partial androgen receptor agonist, can significantly increase lean muscle mass and strength beyond training and nutrition alone.
  • A Myostatin Inhibiting – YK-11 stimulates follistatin production, a potent myostatin inhibitor, so you can maximise your muscle building potential.
  • Safe and SARM – Selective Androgen Receptor Modulators such as Alphaform Labs YK-11 are designed to give you all the muscle building benefits without the nasty side effects usually associated with steroid use.


Alphaform Labs YK-11 capsules are exclusively formulated for healthy male athletes looking to take their performance to the next level and build the most lean mass possible. Alphaform Labs YK-11 capsules are not suitable for women, children or adults under the age of 21. For those with any pre-existing medical condition or currently on prescribed medication, please seek the advice of a medical professional before starting supplementation. Do not use Alphaform Labs YK-11 capsules if you are a competitive athlete subject to testing for performance enhancing substances. Please note that Alphaform Labs YK-11 uses gelatin caps.

What are SARMS?

Selective Androgen Receptor Modulators, more commonly known as SARMs, are intended to have the same kind of effects as androgenic drugs but be much more selective in their action, allowing them to be used for more uses than the relatively limited legitimate uses of anabolic steroids.
