YK-11 (5 mg)

YK-11 (5 mg) is a synthetic compound often categorized within the selective androgen receptor modulator (SARM) family, though it exhibits unique properties that distinguish it from traditional SARMs. It is primarily known for its potential role as a myostatin inhibitor, a protein that limits muscle growth in the body.

By influencing myostatin activity, YK-11 is commonly discussed in research and performance-focused contexts for its potential to promote muscle cell growth and differentiation. Additionally, it may increase follistatin expression, a protein associated with muscle development and recovery.

Due to its distinct mechanism and limited research data, YK-11 is considered an experimental compound and is typically referenced in laboratory and research environments rather than approved clinical use.
