Researchers reach for Follistatin 344 in myostatin-inhibition and muscle-tissue research. It is offered strictly for laboratory investigation — no personal-use claims, no dosing guidance, and no framing as a medicine.
The point of buying research grade rather than generic material is documentation. Every Follistatin 344 order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. The 344-residue isoform, distinct from follistatin 315.

Great documentation
Ordered a bundle to save on shipping - all vials arrived in one insulated pack, labels identical batch, CoA covers the lot. Great value.

Professional service end to end
Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.
Lena P.Amsterdam, NL · 1 May 2026
Very impressed with the CoA
The little details matter - proper cold-chain, tamper-evident seals, and a CoA that actually reads like a lab report and not a marketing sheet.
