Quality packaging, quick dispatch
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.

Semax is a synthetic heptapeptide derived from ACTH (4-10). MyPeptides supplies it as a lyophilised 5 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
Researchers reach for Semax in cognitive, neurotrophic and BDNF-expression 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 Semax order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. The C-terminal Pro-Gly-Pro extension distinguishes it from native ACTH (4-10).

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