Compare the exact selection
Choose the labeled amount per unit and quantity before comparing. A single unit and a multipack have different upfront prices. Keep product format and exact recipe consistent; similar names do not establish equivalent products.
Follow the original listing to check its quantity, availability and current price. Unit prices use the full labeled mass in each selection.

About Follistatin-344
Source profile reviewed 2026-10-01 · Imported 2026-10-22. Read the full compound profile
Follistatin-344 is the longer of the two splice variants of the human FST gene: a 344-residue precursor (UniProt P19883, computed mass 38,007 daltons) whose first 29 residues are a signal peptide, so what the cell actually secretes is the 315-residue circulating protein FST-315. Every human study of follistatin has used this variant rather than injected protein, and the choice was deliberate, because the variant matures into the serum form with roughly ten-fold lower activin affinity than FST-288 and was therefore expected to add muscle without suppressing follicle-stimulating hormone through the pituitary activin axis. Nationwide Children's Hospital delivered rAAV1.CMV.huFS344 into the leg muscles of patients with Becker muscular dystrophy, sporadic inclusion body myositis and Duchenne muscular dystrophy between 2012 and 2017, and a company clinic in Honduras injected an FST-344 plasmid into the abdominal fat of 43 volunteers in a study published as a preprint in 2024. PubChem holds no compound record for any follistatin isoform, so there is no molecular formula, CAS number, InChIKey or molar mass to report here; the protein is indexed only under accession P19883, and the identifier quoted on older pages (178101631) is a PubChem substance number rather than a compound record. Vials sold as Follistatin-344 contain recombinant protein rather than the vector or plasmid the studies used, no human study has injected follistatin protein by any route, and follistatin is not approved anywhere and sits on the WADA prohibited list.
