Swiss Pharmaceuticals YK-11 – Steroidal SARM
Swiss Pharmaceuticals YK-11 contains a synthetic steroidal compound commonly classified as a selective androgen receptor modulator (SARM).
YK-11 has attracted scientific interest because of its interaction with androgen receptors and its potential influence on follistatin expression, a protein involved in the regulation of muscle development.
What is YK-11?
YK-11 differs structurally from many non-steroidal SARMs because it possesses a steroidal molecular structure.
Preclinical laboratory research has investigated its effects on androgen receptor activity and muscle-cell differentiation. Some cellular studies have reported increased follistatin expression, which is associated with the regulation of myostatin signaling.
However, these findings have not established that YK-11 increases muscle mass, strength or athletic performance in humans.
