What is Semax Peptide?

Semax is a synthetic heptapeptide — sequence Met-Glu-His-Phe-Pro-Gly-Pro — originally derived from the ACTH(4-10) fragment of adrenocorticotropic hormone. Unlike ACTH itself, Semax carries no hormonal activity at the adrenal gland; instead, its research interest lies entirely in its central nervous system effects, particularly its influence on neurotrophic factor expression, neuroprotective signalling, and cognitive biology.

Developed originally in Russia in the 1980s, Semax has been the subject of substantial pre-clinical and clinical investigation — making it one of the better-characterised synthetic neuropeptides in the research literature. It is studied primarily for its ability to upregulate Brain-Derived Neurotrophic Factor (BDNF) and related neurotrophins, its neuroprotective properties in models of ischaemia and oxidative stress, and its influence on attention, memory, and learning-related neural circuitry.

Semax is resistant to rapid enzymatic degradation compared to many peptides of similar size, and its CNS activity profile has made it a consistent subject of interest in European neuropeptide research.

What Does Semax Peptide Do in Research?

In laboratory settings, Semax is studied primarily for its effects on neurotrophic signalling, neuroprotection, and cognitive biology. EU and European researchers working with Semax typically focus on:

• BDNF and neurotrophin expression — Semax has been shown in pre-clinical studies to upregulate BDNF, NGF, and VEGF expression in brain tissue, making it a widely used research tool for studying neurotrophic factor biology and neuroplasticity mechanisms.
• Neuroprotection research — studies have examined Semax in models of cerebral ischaemia, oxidative stress, and neuronal injury, where it has demonstrated protective effects on neuronal viability and recovery of function parameters.
• Cognitive function and memory research — Semax influences dopaminergic and serotonergic tone in regions associated with attention and working memory, making it relevant to cognitive biology research and nootropic mechanism studies.
• HPA axis and stress biology — as an ACTH-derived fragment, Semax has been studied for its interactions with stress-related neural circuitry without the peripheral hormonal activity of parent ACTH.
• Neuroinflammation research — studies have characterised Semax’s influence on inflammatory signalling in CNS tissue, including effects on cytokine expression in glial cells.
• Optic nerve and retinal biology — a distinct body of research has examined Semax in models of optic nerve damage and retinal ischaemia, reflecting its neurotrophic profile.

All research applications are for in vitro and pre-clinical use only.

What Do Studies Say About Semax Peptide?

Semax has an unusually broad research base for a synthetic neuropeptide, spanning neurotrophic biology, neuroprotection, and cognitive pharmacology across decades of pre-clinical and early clinical investigation.

BDNF and neurotrophin upregulation: Studies have documented Semax-induced increases in BDNF, NGF, and VEGF expression in rodent brain tissue — particularly in the hippocampus and cortex. This neurotrophic activity is considered central to its neuroprotective and cognition-relevant research profile, and positions Semax as a useful tool for studying the upstream regulation of neurotrophin expression.

Neuroprotection in ischaemia models: A significant body of pre-clinical literature has examined Semax in models of cerebral ischaemia and stroke. Studies have reported reductions in infarct size, improvements in neurological deficit scores, and enhanced survival of vulnerable neuronal populations in rodent ischaemia models — findings that have driven continued research interest in Semax as a neuroprotective research tool.

Cognitive and attention biology: Pre-clinical studies have characterised Semax effects on dopaminergic and serotonergic transmission in prefrontal and hippocampal regions implicated in working memory and sustained attention. Research has documented improvements in maze learning, spatial memory, and attention task performance in rodent models.

Neuroinflammation: Studies examining Semax in CNS inflammatory models have characterised effects on pro-inflammatory cytokine expression — including IL-1β and TNF-α — in glial cell populations, contributing to the proposed neuroprotective mechanism.

Optic nerve research: A distinct line of investigation has studied Semax in optic nerve transection and retinal ischaemia models, with findings suggesting neurotrophic support for retinal ganglion cells — an application reflecting its broader neurotrophin-upregulating profile.

Frequently Asked Questions — Semax Peptide EU

Can I Buy Semax in the EU and Europe?

Yes. We supply research-grade Semax peptide with fast tracked international dispatch to all EU member states and wider European destinations. Packaging is designed to maintain peptide integrity throughout transit, and all orders include full batch documentation. Semax is supplied strictly for laboratory research use only.

What is the Difference Between Semax and ACTH?

Semax is derived from the ACTH(4-10) fragment — a short sequence within the larger ACTH hormone. While ACTH acts on adrenal glands to stimulate cortisol production, Semax carries none of this peripheral hormonal activity. Its research relevance is entirely CNS-focused, particularly around neurotrophic factor expression and neuroprotective signalling, which are properties not shared with parent ACTH.

What is BDNF and Why is it Relevant to Semax Research?

Brain-Derived Neurotrophic Factor (BDNF) is a key neurotrophin supporting neuronal survival, synaptic plasticity, and the cellular mechanisms underlying learning and memory. Pre-clinical studies have documented that Semax upregulates BDNF expression in hippocampal and cortical brain regions — making it a widely used research tool for studying how neurotrophic factor modulation influences neural function, neuroprotection, and cognitive biology.

What is the Difference Between Semax and NA-Semax?

NA-Semax (N-Acetyl Semax) is an acetylated variant of Semax in which an acetyl group is added to the N-terminus of the peptide. The acetylation is believed to improve CNS penetration and extend biological activity compared to standard Semax, while preserving the core neurotrophic and neuroprotective research profile. The two compounds are studied as complementary tools in comparative neuropeptide research.

What is the Difference Between Semax and Selank?

Semax and Selank are both synthetic neuropeptides with CNS research profiles, but they differ in origin and primary research focus. Semax is derived from ACTH(4-10) and is primarily studied for neuroprotection, BDNF upregulation, and cognitive biology. Selank is derived from the immunomodulatory peptide tuftsin and is primarily studied for anxiolytic effects, immune modulation, and memory biology. They represent complementary rather than overlapping research tools.

How Do I Reconstitute Semax for Laboratory Use?

Allow the vial to reach room temperature before opening. Add sterile water or an appropriate laboratory buffer slowly down the vial wall and swirl gently — do not shake. Prepare at your protocol’s required concentration, aliquot, and store at -80°C to minimise freeze-thaw degradation. Standard peptide handling protocols apply.

How Quickly is Semax Delivered to Europe?

Orders are dispatched promptly via tracked international courier. Delivery to EU and European destinations typically takes 3–7 working days depending on location, with packaging designed to protect peptide stability throughout transit.
