About Follistatin-344

What it is
Follistatin-344 is the longer follistatin form encoded by the full-length FST transcript, which after processing yields the mature circulating protein. It is a secreted glycoprotein that binds and neutralizes transforming growth factor beta proteins, including activin and myostatin. Because myostatin restrains muscle growth, a virus carrying the follistatin-344 sequence was tested in an early human gene therapy trial for muscle disease. It has not been approved for any use.
How it works
It binds activin and myostatin, blocking their access to activin type II receptors and relieving suppression of muscle growth.
Researched for
Muscle growth research; myostatin inhibition; activin neutralization; muscular dystrophy research

Research evidence
Human trials - early or small

Phase 1
Key risk
No serious risk is documented in the small human gene therapy trial, though broad interference with growth factor signaling remains a theoretical concern.

Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
