What is YK-11?

YK-11, also known as Myostine, is a synthetic steroidal selective androgen receptor modulator (SARM) and myostatin inhibitor. It is commonly studied for its potential to promote muscle growth by increasing follistatin levels, which in turn may suppress myostatin—a protein that limits muscle development. YK-11 is frequently explored in research focused on muscle hypertrophy and strength enhancement.

YK-11 Research Based Facts

• May support studies on muscle mass increase and strength development
• Known for its potential role in myostatin inhibition and follistatin expression
• Could aid in research on sarcopenia and age-related muscle loss
• Useful for investigations into anabolic activity with selective androgenic effects
• May contribute to improved performance, recovery, and lean body composition in studies

Studies/Resources

• YK11 promotes osteoblast proliferation and differentiation via androgen receptor activation (Biol Pharm Bull, 2018)

• YK11 reverses muscle atrophy in septic mice by inhibiting myostatin (Biochem Biophys Res Commun, 2021)
