Follistatin
Also known as FS-344, Follistatin-344
Follistatin is a protein that blocks myostatin — the body's 'brake' on muscle growth — which is why it's of interest for building muscle. Still largely experimental.

- 100 mcg
Glycoprotein that binds and neutralizes myostatin and activin, of interest for muscle growth.
Mechanism of action
Sequesters myostatin (GDF-8) and activin A, relieving their inhibition of muscle growth.
Research protein — no approved human use. No human protein pharmacokinetics exist (human work is gene therapy); half-life and the ~100 mcg dose are rough estimates.
