Myostatin 1 mg (1 vial)

YK-11 is a unique compound that acts as both a SARM and a potent Myostatin inhibitor. Myostatin is a member of the transforming growth factor-beta (TGF-β) superfamily and functions as a negative regulator of muscle growth. Essentially, it is the protein responsible for signaling the body to stop producing muscle.

YK-11 works by inducing the muscle cells to produce more Follistatin, an antagonist to Myostatin. This protein undergoes complex post-translational modifications, including proteolytic cleavage and dimerization, to achieve its biologically active form. By increasing Follistatin levels, YK-11 effectively blocks Myostatin’s inhibitory cellular signaling pathways, allowing for muscle cell proliferation far beyond natural biological limits.

Human Research & Potential Applications

Due to its ability to modulate the TGF-β superfamily, YK-11 is at the forefront of research regarding:

• Hypertrophy beyond Genetic Limits: Research suggests YK-11 is more anabolic than traditional steroids by specifically targeting Myostatin suppression.

• Bone Health: By increasing protein levels in bone cells, it may enhance bone mineralization and overall skeletal strength.

• Muscle Wasting Prevention: Potential applications in treating severe muscle atrophy and age-related muscle loss (sarcopenia).
