YK-11 (Myostatin) – [20mg]

YK-11 is a unique selective androgen receptor modulator (SARM) because it not only binds to androgen receptors like other SARMs but also acts as a myostatin inhibitor. Myostatin is a natural protein in the body that limits muscle growth. By suppressing it, YK-11 creates an environment where muscle development can go beyond normal genetic potential.

Athletes and bodybuilders value YK-11 for its potent anabolic effects, promoting rapid increases in lean muscle mass, strength, and hardness. Because of its dual mechanism, it is often considered one of the most advanced and powerful SARMs available.

YK-11 is generally used by experienced users looking for dramatic physique changes and performance boosts, particularly during bulking or recomposition cycles.

Key benefits may include:

• Inhibition of myostatin, unlocking greater muscle growth

• Rapid lean muscle gains and strength increases

• Enhanced hardness and definition

• Support for recomposition (gaining muscle while reducing fat)

• One of the most advanced SARMs for physique enhancement

YK-11 is often seen as a hybrid compound — combining the muscle-building effects of SARMs with the unique ability to push beyond natural growth limitations through myostatin inhibition.
