What is Semax?
Semax is a synthetic heptapeptide. It consists of the fragment ACTH(4–7) of adrenocorticotropic hormone, extended by the tripeptide sequence Pro-Gly-Pro.
The added sequence increases stability against peptidases. Semax was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences.
Semax in research
In animal models, Semax is studied in connection with neurotrophic factors, especially the expression of BDNF (brain-derived neurotrophic factor).
Other preclinical work concerns models of neuroprotection and cognitive processes. Much of the literature comes from Russian research institutions.

What you receive
You receive a sealed glass vial containing 10 mg Semax as a lyophilised powder. The label states the product name, content and batch number, so every vial can be matched clearly to the corresponding test report.
Orders are shipped in neutral, padded packaging. No instructions for human use are included, because the product is intended exclusively for laboratory research.
Quality: what matters when you buy Semax

If you want to buy Semax, look above all for traceable batch documentation. We publish available third-party test reports in our certificate of analysis library. There you can see which tests – such as HPLC for purity or mass spectrometry for identity – exist for the specific batch.
General substance data on Semax is also available in the free PubChem database of the US National Center for Biotechnology Information.
Laboratory storage
Lyophilised peptides are considerably more stable in dry form than in solution. For laboratory storage, −20 °C, dry and protected from light, is recommended. Room temperature for short periods, for example during shipping, is not critical.
Repeated freeze-thaw cycles should be avoided. Further handling follows your laboratory's requirements and standard operating procedures (SOPs).

Frequently asked questions
How do Semax and Selank differ?
Both are heptapeptides ending in Pro-Gly-Pro. Semax is derived from an ACTH fragment, Selank from the immune peptide tuftsin.
How quickly do you ship?
When you buy Semax and pay by bank transfer, we ship within 1–2 business days of receiving payment. DHL delivery within Germany usually takes 1–3 business days. See shipping & payment for details.
Is Semax intended for human use?
No. Semax is sold solely as a research substance for in-vitro studies. It is not a medicine, a food or a cosmetic. Read more under Research Use Only.
