You can buy Semax from HEEZ Research, which stocks it in a single 10 mg lyophilized vial and ships from the USA. Everything HEEZ supplies is for in vitro laboratory research — not for human or veterinary use.
Semax is a synthetic heptapeptide composed of the ACTH(4-7) fragment extended with proline-glycine-proline. The extension is a stabilising modification rather than part of the native fragment.
It denotes residues four through seven of ACTH — the short region Semax is built on. The notation is standard for naming a peptide by its position in a parent sequence.
Yes — Semax from HEEZ Research is independently tested by an accredited third-party laboratory using HPLC for purity and mass spectrometry for identity. Every peptide we supply is over 99% pure. Certificates of Analysis are published on the product page as testing is completed — review the report before you order. A certificate records the identity, purity and quantity measured for the material supplied, so you can confirm what you received matches what was ordered.
Sealed lyophilized Semax vials are stable at ambient temperature in transit and ship without cold packaging. On arrival, store the sealed vial per the storage conditions on its certificate of analysis.
Semax is available to buy for research from HEEZ Research as a research-use-only compound supplied to qualified laboratories and independent researchers. Checkout requires an institutional email matching your stated organization, and everything we supply is for in vitro laboratory research — not for human or veterinary use.

About Semax
What is semax peptide?
Semax peptide is a synthetic heptapeptide — Met-Glu-His-Phe-Pro-Gly-Pro — derived from the ACTH(4-7) fragment with a Pro-Gly-Pro tail added to resist enzymatic degradation, supplied by HEEZ Research as a lyophilized powder for in vitro laboratory use.
How does semax work?
In vitro, semax retains the ACTH(4-7) core but shows no MC2R activity, which is why it is studied as a distinct entity from ACTH; its stability in assay media is conferred by the Pro-Gly-Pro tail.
How HEEZ tests semax
Solid-phase synthesis, reversed-phase purification, lyophilization.
