Follistatin 344 is follistatin 344, a myostatin-binding research protein, supplied by MyPeptides for laboratory research use only.
Follistatin 344 is follistatin 344, a myostatin-binding research protein. MyPeptides supplies it as a lyophilised 1 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
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.

Ordered a bundle to save on shipping - all vials arrived in one insulated pack, labels identical batch, CoA covers the lot. Great value.
Site was easy to use, checkout was fast, and the product arrived exactly when they said it would. Straightforward, no drama, high quality.
Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.
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.
Been using peptides for research for years and MyPeptides is now my go-to. Consistent quality, quick turnaround, real documentation.
