What is YK11
YK11 is a selective androgen receptor modulator (SARM) with a unique mechanism that goes beyond standard androgen receptor activity. It is known for its ability to influence myostatin pathways, a key regulator that limits muscle growth.
By interacting with these pathways, YK11 is often associated with supporting increased muscle development and strength progression.

Joe Davies –
Pretty happy thus far with the YK11, i’m on a recomp at the moment but I am steadily gaining muscle with no extra fat based on a clean 3500 calorie per day diet. generally if i am on 3500 i drop off due to my metabolism but hasnt been an issue
