Semax: Peptide Profile
Sequence, molecular data, research status and testing standards for Semax — written for Canadian researchers.
What Is Semax?
Semax is a synthetic heptapeptide derived from the ACTH(4-10) fragment with a C-terminal Pro-Gly-Pro extension, studied in neuropeptide research.
What the Research Says About Semax
Semax was developed in Russia, where it has been studied in neurological research. Most of the published literature comes from Russian institutions, and it is not authorized as a drug in Canada.
Peptide Authority summarizes published research for educational purposes only. Nothing here is medical advice or a claim that Semax is safe or effective for any use.
Semax Storage & Handling
Lyophilized (freeze-dried) Semax is most stable frozen at −20°C or colder for long-term storage, or refrigerated at 2–8°C for short periods. Keep vials sealed, dry and away from light, and allow them to reach room temperature before opening to prevent condensation.
What to Look for in a Semax Certificate of Analysis
- HPLC purity of 98–99% or higher, shown as a chromatogram with one dominant peak
- Mass spectrometry with an observed mass matching 813.9 g/mol
- A lot number that matches the label on your vial
- An independent, named laboratory and a recent test date

Is Semax Legal in Canada?
Semax is not authorized by Health Canada as a drug. It may only be sold in Canada as a research chemical for in-vitro laboratory use — not for human or animal consumption. Read how peptides are regulated in Canada.
Semax FAQs
What is Semax?
Semax is a synthetic heptapeptide derived from the ACTH(4-10) fragment with a C-terminal Pro-Gly-Pro extension, studied in neuropeptide research. It is also known as ACTH(4-7)-Pro-Gly-Pro, MEHFPGP.
Is Semax legal in Canada?
Semax is not authorized by Health Canada as a drug, so it cannot legally be sold for human or animal use. In Canada it is sold as a research chemical for in-vitro laboratory use only. This is general information, not legal advice.
Where can I buy Semax in Canada?
Peptide Authority supplies HPLC-tested, lot-coded Semax for research use, now serving Edmonton with Canada-wide shipping coming soon. Wherever you buy, insist on a third-party COA that matches the lot number on your vial.
How should Semax be stored?
Store lyophilized Semax frozen at −20°C for long-term stability or refrigerated at 2–8°C short-term, protected from light and moisture.
