Description

YK-11 – 12mg
(Myostatin Inhibitor / SARM Hybrid)

YK-11 is a unique research compound that functions as a selective androgen receptor modulator (SARM) with additional activity as a myostatin inhibitor. Unlike traditional SARMs, YK-11 has been shown in preclinical studies to increase follistatin expression, a natural inhibitor of myostatin—a protein that limits muscle growth.

Due to this dual mechanism, YK-11 is often studied in models focused on extreme hypertrophy, muscle regeneration, and cellular differentiation.

Mechanism of Action (Based on Preclinical Research):

• Binds to androgen receptors to promote anabolic signaling

• Upregulates follistatin, which inhibits myostatin, removing natural limitations on muscle growth

• May enhance muscle satellite cell activation and differentiation

Potential Benefits (Based on Preclinical Research):

• Accelerated lean muscle growth and strength

• Increased muscle fiber density and hardness

• Support for muscle regeneration and recovery

• Potential application in muscle-wasting and degenerative research models
