How is Semax used in research?
Semax is a synthetic heptapeptide analog of the ACTH (4-10) fragment (Met-Glu-His-Phe-Pro-Gly-Pro), developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. Unlike the parent ACTH molecule, Semax lacks hormonal (steroidogenic) activity while retaining and enhancing the neurotropic effects associated with the ACTH (4-10) sequence in preclinical models. The addition of the Pro-Gly-Pro C-terminal tripeptide confers resistance to enzymatic degradation and extends the peptide's biological activity in research models.
Preclinical research has characterized Semax's activity in cognitive-research preclinical models in animals, including learning, memory, and attention research markers. A key mechanism involves the upregulation of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) expression in preclinical brain tissue, particularly in the hippocampus and prefrontal cortex. Studies have also shown that Semax modulates dopaminergic, serotonergic, and cholinergic neurotransmitter systems in preclinical systems.
Significant research has investigated Semax in neuroprotective assay models of ischemic stroke. Studies have demonstrated infarct-volume parameter modulation, improvements in neurological research readouts, and modulation of gene-expression patterns related to inflammatory and apoptotic markers following cerebral ischemia in research models. The peptide's ability to cross the blood-brain barrier via intranasal administration has facilitated preclinical research applications.
Areas of Study
Neuroprotective Assay Models
Demonstrated infarct-volume parameter modulation and neurological readouts in ischemic stroke research models through anti-apoptotic and inflammatory-marker modulation mechanisms.
Cognitive Enhancement
Investigated for improvements in learning, memory consolidation, and attention through modulation of multiple neurotransmitter systems.
BDNF Expression
Research shows upregulation of brain-derived neurotrophic factor and nerve growth factor in hippocampal and cortical regions.
Stroke Research Models
Extensively studied in cerebral ischemia research models with reported neuroprotective assay model activity and modulation of post-ischemic gene expression.
Neurotransmitter Modulation
Influences dopaminergic, serotonergic, and cholinergic pathways without the steroidogenic activity of the parent ACTH molecule.

Questions
Everything on purity, paperwork, shipping and the research-use-only terms. Still stuck? Read the full FAQ.
What does research use only mean?
Every compound we supply is a reference standard intended strictly for in-vitro laboratory research. It is not a drug or a supplement, and it is not for human or veterinary use, nor for diagnostic or therapeutic use.
How is purity verified?
Every lot is assayed by HPLC at an independent, accredited third-party laboratory. We publish the resulting Certificate of Analysis and link it to the lot number printed on the vial.
Where do I find the Certificate of Analysis?
Every lot has a public, batch-linked COA. Browse them all on the COA page, or open any product page and use the COA tab for that specific compound.
How quickly do orders ship?
Orders placed before 2PM EST ship the same business day. Shipments are cold-packed where required and fully tracked.
Do you ship internationally?
We currently ship within the United States. Requests from institutional buyers outside the US are handled case by case, so contact us before ordering.
