Buying Semax — Frequently Asked Questions

What purity documentation ships with Semax?

Semax is sourced to a >=99% by HPLC standard, and each batch has a Certificate of Analysis with the HPLC chromatogram and mass spectrometry identity confirmation. The >=99% figure is a sourcing specification; the batch-specific measured value is the number printed on that batch CoA.

How should Semax be stored?

Keep the lyophilized powder at -20C, sealed and protected from light. Once reconstituted, hold the solution at 2-8C away from light and aliquot into single-use volumes if the work will run for weeks, so no aliquot goes through repeated freeze-thaw. A published solution stability window for this peptide is not publicly disclosed, so treat your own stability data as the reference.

Can Semax be used in human or veterinary applications?

No. This material is sold exclusively for in-vitro and preclinical laboratory research by qualified personnel. It is not a drug, supplement or food, and it is not for human or animal consumption in any form.

Is Semax FDA approved?

No. Semax has no FDA approval for any indication in the United States. It is registered as a medicine in Russia, which is why much of its clinical literature appears in Russian-language journals. Material supplied here is a research chemical.
