Peptide Reference
GDF-8 Propeptide
Growth Differentiation Factor-8 Propeptide
The natural inhibitor of myostatin (GDF-8). Myostatin puts 'brakes' on muscle growth; this propeptide releases those brakes.
Status
research
Category
muscle
Typical cost
Not commercially available
Mechanism
Binds to and inhibits myostatin, preventing it from limiting muscle growth. Allows for muscle development beyond normal genetic limits. Natural regulatory mechanism.
Potential benefits
- Potential muscle growth
- Myostatin inhibition
- Natural mechanism
Reported side effects
- Unknown
- Theoretical cancer risks
- Safety not established
