How we test
Certificates are issued by BioRegen, an independent lab. Identity and purity are measured by LC-MS; endotoxin, where listed, by a LAL screen. The latest report for this product: Identity, purity & endotoxin tested, lot SMX30N, tested 28 May 2026.
How to read your COA
Start with the lot number on the report. Identity confirms by mass spectrometry that the molecule is the one on the label. Purity is the share of the sample that is the target peptide, measured by LC-MS. Endotoxin, where tested, is screened by LAL and must sit below 0.5 EU/mL. The lab name and test date show who ran it and when.

What is Semax and what is its structural derivation?
Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) derived from the N-terminal ACTH(4-10) sequence with a C-terminal Pro-Gly-Pro extension. ACTH(4-10) is the minimal melanocortin receptor-binding fragment of adrenocorticotropic hormone. The Pro-Gly-Pro tripeptide addition in Semax increases stability against proteolytic degradation while altering the pharmacological profile relative to the parent ACTH fragment.
What receptor interactions has Semax been investigated for in research?
Preclinical research has investigated Semax for interactions with melanocortin receptors — particularly MC4R expressed in the central nervous system — as well as effects on BDNF expression in neuronal cell models, neurotrophic signalling pathway activation (TrkB, PI3K/Akt, MAPK), and enkephalin-degrading enzyme inhibition. Research has also examined effects on gene expression in hippocampal and cortical neuronal preparations using transcriptomic approaches.
What neurotrophic pathway research has been conducted with Semax?
Published preclinical research has examined Semax’s effects on BDNF mRNA and protein expression in rat brain preparations and primary neuronal cultures, activation of CREB transcription factor as a downstream target of TrkB/cAMP signalling, and expression of other neurotrophic factors (NGF, NT-3) in hippocampal models. These studies use standard qRT-PCR, ELISA, and Western blot endpoints to characterise the compound’s effects on defined neurotrophic signalling parameters.
How should Semax be stored and reconstituted for research use?
Semax is supplied as a lyophilised powder and should be stored at -20°C. It is generally soluble in sterile water or PBS at physiological pH. The presence of the N-terminal methionine makes it susceptible to oxidation — stock solutions should be prepared under nitrogen atmosphere where possible and stored in single-use aliquots at -80°C to prevent Met oxidation during storage.
What controls are standard in Semax research experiments?
Standard controls include vehicle alone (matched buffer without peptide), a scrambled sequence control to confirm sequence specificity, and reference compounds with established activity at the target pathway (e.g. recombinant BDNF for neurotrophic endpoint assays, α-MSH for melanocortin receptor assays). Concentration-response experiments over a minimum 4-log concentration range establish potency and confirm the dose-dependence of observed effects.
Is Semax for human use?
Semax has been used in clinical and research contexts in Russia. As supplied by Elivena, Semax is a research-grade compound for use in controlled laboratory settings only. It is not supplied for human administration outside of formally regulated research and clinical contexts.

Researchers often ask
Is Semax for human use?
No. Semax is sold for laboratory research only. It is not for human or veterinary use, and it is not a drug, food or cosmetic.
How do I find the lab report?
Use View COAs on the product page, or search the COA library by compound name. The summary is public; the signed PDF reports are available to signed-in researchers.
Why is purity measured by LC-MS?
LC-MS separates the sample and identifies each component by its mass, so one run confirms identity and measures purity.
When will my order ship?
Orders are dispatched within 1 to 3 business days. Regular tracked delivery takes 5 to 10 days and express tracked 3 to 5 days. Regular shipping is free on orders over $200 and express on orders over $400, after discounts.
