What Is Semax?
Semax is a seven-amino-acid peptide built from the Met-Glu-His-Phe core of adrenocorticotropic hormone (ACTH 4–7) with a Pro-Gly-Pro tail added at the C-terminus. The tail protects the peptide from rapid enzymatic breakdown, giving it a working life in cell and tissue systems that the native fragment lacks. Our Semax 10mg vial contains the sequence MEHFPGP, with a molecular weight of approximately 813.9 Da.
Semax was developed in Russia in the 1980s and has since been studied extensively as a neuropeptide tool compound. The lyophilised format keeps the peptide stable in storage; researchers who need a ready-made solution can also choose our Semax + Selank nasal spray.
Semax Research Areas
Laboratory studies of Semax cover the following areas of the published literature:
Neurotrophin Expression
Semax is best known in the literature for its effects on brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) expression in neuronal cultures and preclinical models. Published work can be explored on PubMed.
Neuroprotection Models
Cell and tissue models of oxidative stress, ischaemia and excitotoxicity use Semax to study protective signalling pathways.
Melanocortin Receptor Pharmacology
As an ACTH fragment analogue, Semax is used in melanocortin-receptor binding and signalling studies alongside other MC-receptor ligands.
Learning and Memory Models
Preclinical behavioural research examines Semax in models of attention, learning and memory consolidation.
Semax vs Selank
Semax and Selank are both Russian-developed heptapeptides with a Pro-Gly-Pro tail, but they derive from different parent molecules: Semax from ACTH, Selank from the immunomodulatory tetrapeptide tuftsin. Semax is primarily studied in neurotrophin and neuroprotection models, Selank in anxiety-related and immune-signalling models. Many laboratories study them side by side.

Quality Control and Batch Testing
Every batch of Semax 10mg is analysed before release. HPLC confirms purity, and mass spectrometry confirms that the peptide mass matches the expected sequence. You can view current certificates on our verification and testing page.
Storage and Handling
Store lyophilised Semax at −20°C for long-term stability, protected from light and moisture. Reconstitute with bacteriostatic water using aseptic technique, then keep the solution refrigerated at 2–8°C and use promptly. See our guides on how to reconstitute peptides and how to store research peptides.
