GDF-8 is growth differentiation factor 8, better known as myostatin, supplied by MyPeptides for laboratory research use only.
GDF-8 is growth differentiation factor 8, better known as myostatin. 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 GDF-8 in muscle-tissue and TGF-β family 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 GDF-8 order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. Supplied as the ligand itself, for use as a reference against inhibitors like follistatin.

Very impressed with the CoA
Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.

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