YK-11 is unique among SARMs because it acts as both a selective androgen receptor modulator and a myostatin inhibitor.

Dual Mechanism

YK-11 activates androgen receptors while also inhibiting myostatin to unlock muscle growth.

Research Effects

• Muscle growth beyond genetic limits
• Increased follistatin
• Strength gains

Considerations

YK-11 is potent and suppressive. Liver support and full PCT are recommended.

Dosing

5-15mg daily for 8 weeks maximum.
