Semax Research Peptide
Semax is a synthetic heptapeptide that joins the ACTH(4-7) fragment to a Pro-Gly-Pro extension, developed in Russia for neurotrophin and neuropeptide research.

About Semax
Semax is built from the ACTH(4-7) sequence Met-Glu-His-Phe, which has no activity at the adrenal ACTH receptor, followed by Pro-Gly-Pro, a tripeptide that protects it from rapid degradation. It was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences.
Because it lacks the adrenal-stimulating part of ACTH, it is studied for central nervous system effects rather than corticosteroid release.
Research context
Semax is studied in research on BDNF and neurotrophin expression, cerebral ischemia models and neuropeptide effects on attention and memory tasks in rodents. Analogues such as Adamax and combinations such as the Selank + Semax blend derive from it.
What to confirm for Semax
Check these points with our team before you order:
- Whether the lot is standard Semax or a modified form such as N-acetyl Semax amidate; the two differ in structure.
- The number of boxes you need and the US delivery destination.
- Which lot documents you require before ordering, such as an identity or purity report.
Semax: frequently asked questions
Is Semax the same as ACTH?
No. Semax contains only a four-residue fragment of ACTH, positions 4-7, plus a Pro-Gly-Pro extension, and it does not act on the adrenal ACTH receptor.
Which Semax presentations are listed?
2 presentations are listed: 5 mg (XA5), 10 mg (XA10). Each is packed 10 vials per box, and every presentation has its own specification page and product code.
How do I request a quote for Semax?
Open the presentation you need and use Ask price to message PureForm Biosciences on WhatsApp, or add several materials to the inquiry cart and send them together. Pricing, current availability and lot documents are confirmed in that conversation.
