In laboratory settings, YK-11 has been observed to significantly increase the production of follistatin, a protein that acts as a potent myostatin inhibitor. Myostatin is a regulatory protein that limits muscle growth; therefore, inhibiting it can potentially lead to enhanced muscle development. By stimulating follistatin, YK-11 may promote lean muscle mass and strength beyond what is achievable through training and nutrition alone, offering valuable insights into muscle-building mechanisms.
The dual action of YK-11 as both a partial androgen receptor agonist and a myostatin inhibitor sets it apart from other compounds in its category. This unique profile makes it a valuable compound for preclinical research focused on understanding muscle hypertrophy and the regulation of muscle mass. Studies involving YK-11 aim to explore its potential applications in conditions related to muscle wasting and osteoporosis, contributing to the advancement of knowledge in muscle biology and therapeutic development.
The Bottom Line: YK-11 promotes muscle growth in studies by stimulating follistatin production and inhibiting myostatin.
