This SARM gets a ton of attention due to its unique ability to (possibly) inhibit Myostatin conversion in the human body. More research needs to be done to fully understand how this mysterious SARM works, but anecdotal reports from users show that YK11 is an extremely powerful compound when used correctly.

I will continue to update this page as I publish new articles about YK11.

YK11 is best for:

  • Adding a second or third compound to a stack
  • Lean mass gains with no estrogen conversion
  • Retaining muscle during a cut
