Important Notice
This product is intended for laboratory and research use only. Not for human or veterinary use. By purchasing, you confirm this product will be used exclusively for in-vitro research purposes.
Reconstitution Required
This peptide ships lyophilized (dry powder) and requires bacteriostatic water to reconstitute before use. BAC water is sold separately.
Recommended: PBS · stable for 14 days at 2-8°C once mixed.
When This Product May Not Suit Your Research
- ⚠If your research requires oral administration — Semax is an intranasal peptide and degrades in the GI tract.
- ⚠If your study needs a compound with FDA regulatory history — Semax has no FDA regulatory pathway.
- ⚠If your protocol requires standardized dosing guidelines — no international consensus dosing exists for Semax.

About Semax
About Semax
Semax (CAS: 80714-61-0) is a synthetic heptapeptide derived from the ACTH(4-7) fragment (Met-Glu-His-Phe) with an appended Pro-Gly-Pro tripeptide sequence to enhance metabolic stability. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Semax retains the neurotrophic properties of the parent ACTH fragment while resisting rapid enzymatic degradation.
Mechanism of Action
Semax influences multiple neurotransmitter systems and neurotrophic pathways. It has been shown to upregulate brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) expression in experimental models. The peptide modulates dopaminergic, serotonergic, and cholinergic neurotransmission. Research also indicates effects on gene expression patterns related to neuronal survival and plasticity, involving activation of signaling cascades including the MAPK/ERK pathway.
