In short: Semax is a synthetic heptapeptide derived from an ACTH fragment, studied in pre-clinical models of neurotrophic and neuromodulatory signalling. It is supplied strictly for laboratory research and is not approved for human use in most jurisdictions. For research buyers, the key purchasing criteria are verified purity (≥99% HPLC), confirmed identity (mass spectrometry) and batch traceability.
What is Semax?
Semax is a synthetic heptapeptide based on the ACTH(4-10) fragment of adrenocorticotropic hormone, with a C-terminal Pro-Gly-Pro sequence added to extend its stability. Unlike the parent hormone, it is not reported to stimulate adrenal steroidogenesis. It is used as a research compound; note that while Semax is an approved prescription medication in Russia, it is not approved or marketed in most other countries and here is supplied for in-vitro research only — it is not a medicine for human use.
What does the research investigate?
Published pre-clinical literature has examined Semax in models of brain-derived neurotrophic factor (BDNF) and TrkB signalling, and dopaminergic and serotonergic activity. Much of this work originates from Russian research groups and has not been replicated in large randomised Western trials. Important: these findings are largely in-vitro or in animals and do not establish safety or efficacy in humans. Always read the primary sources directly.
Purity and quality: what research buyers should check
For reproducible research, compound quality is everything:
- ≥99% purity by HPLC — confirm via the batch Certificate of Analysis.
- Identity by mass spectrometry — confirms the correct molecular weight.
- Batch numbering — traceability to a tested lot.
Vexar Lab supplies Semax as a pack of 10 vials, ≥99% HPLC-verified, batch-numbered, with mass-spec confirmation.
Handling and storage
Follow standard lyophilised-peptide practice: store sealed vials appropriately, reconstitute with the diluent specified by your method, and record batch numbers in your lab notes.
