What is Semax?

Semax is a synthetic heptapeptide based on a fragment of adrenocorticotropic hormone (ACTH), specifically the ACTH(4-7) sequence (Met-Glu-His-Phe) with an added Pro-Gly-Pro C-terminal tripeptide for enhanced stability.

Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Semax has been studied extensively in preclinical models. Published research has examined its effects on BDNF expression, neurotrophic factor modulation, and related signaling pathways.

Manufactured under cGMP-equivalent protocols and verified to ≥99% purity via HPLC. Full COA included with every order.

Supplied as a lyophilized white powder. Soluble in sterile water. For research and laboratory use only.
