Follistatin-344
Follistatin-344
A naturally occurring protein that inhibits myostatin, a negative regulator of muscle growth. Synthetic version used for muscle hypertrophy and performance enhancement.
Typical Cost
$150-300/vial (1mg)
Status
Research
Peptide Profile
Follistatin-344
Mechanism of Action
Binds to and neutralizes myostatin and related proteins (GDF-11, activin), removing the 'brakes' on muscle growth. Allows for significantly enhanced muscle protein synthesis and satellite cell activation.
