Follistatin 344 is a recombinant form of the naturally-occurring glycoprotein (344-residue splice variant) that inhibits activin and myostatin signaling. Clinical validation exists ONLY through small AAV gene-therapy phase 1/2 trials in Becker muscular dystrophy; recombinant injectable protein sold on the grey market has no clinical evidence. NOT FDA-approved. WADA-prohibited (myostatin inhibitor) and banned in competitive sport.

How are Follistatin 344 prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
AAV1-FS344 intramuscular gene therapy Phase 1/2a in Becker muscular dystrophy (n=6) reported improved 6-minute walk test and quadriceps volume changes (Mendell et al., Molecular Therapy, 2015). Preclinical mdx mouse and cynomolgus primate studies showed durable muscle mass and strength increases (Kota et al., Science Translational Medicine, 2009). Recombinant Follistatin-344 protein sold as an injectable research chemical has NO validated human clinical data — all positive human evidence is from AAV gene therapy, not peripheral protein injection. Not FDA-approved. WADA-prohibited at all times.
