About YK11 10mg
What Is YK11?
YK11 is a steroidal SARM with myostatin-inhibiting properties — a unique dual mechanism not found in other SARMs. It acts as a partial androgen receptor agonist while simultaneously stimulating follistatin expression, which in turn inhibits myostatin (the primary negative regulator of muscle growth). This dual action makes YK11 particularly interesting for muscle biology research.
Key Research Areas
- Dual AR agonism + myostatin inhibition mechanisms
- Follistatin expression upregulation via AR signaling
- Muscle hypertrophy pathways beyond pure AR activation
- Osteoblast differentiation and bone formation markers
