Product details
Semax Australia. Semax is the cognitive peptide. The research reports better memory and learning, sharper attention and focus, and more resistance to mental fatigue under load. The larger half of the literature is neuroprotection, reporting recovery of function after stroke and brain injury, where Semax has decades of clinical use behind it in Russia and remains on the state medicines list there. Smaller strands cover attention disorders and optic nerve conditions.
How it does it. Semax is a peptide of seven amino acids. It takes a short fragment of ACTH, one of the body's own hormones, and adds a three amino acid tail that stops enzymes breaking it apart. It works by raising BDNF, the protein neurons rely on to survive, grow new connections and adapt, and by increasing activity at trkB, the receptor BDNF acts through.
The vial. Independently HPLC-tested by Janoshik, with the certificate of analysis published on this page and in the lab-reports library, carrying the measured number and a verifiable Janoshik key. Supplied in 10 mg freeze-dried vials, dispatched from Australia, AUD pricing. Supplied strictly for in-vitro and laboratory research use only. Not for human or animal consumption, not a therapeutic good, not TGA-approved.

Semax (CAS 80714-61-0; molecular formula C37H51N9O10S, average molecular weight ≈ 814 g/mol; sequence MEHFPGP) is a synthetic heptapeptide derived from the ACTH(4-10) fragment, extended at the C-terminus with a Pro-Gly-Pro motif that stabilises the peptide against enzymatic degradation. It is referenced as the leading pro-cognitive nootropic research peptide in the literature.
Its neurotrophic mechanism has been characterised in research models: Dolotov and colleagues (Brain Research, 2006) reported that Semax raises hippocampal BDNF (brain-derived neurotrophic factor) protein and exon-specific BDNF mRNA and increases trkB-receptor phosphorylation, implicating the BDNF/trkB signalling system.
A companion study by Dolotov and colleagues (Journal of Neurochemistry, 2006) demonstrated specific, saturable binding of the peptide together with a rapid rise in basal-forebrain BDNF protein — evidence for a receptor-mediated neurotrophic mechanism. These anchor Semax as a reference peptide for BDNF-pathway research.
Semax is most frequently studied alongside Selank — the two form the canonical "nootropic pair" in research literature, Semax framed as the pro-cognitive (BDNF / neurotrophic) partner and Selank as the anxiolytic / GABAergic partner. See the Selank product page for the partner compound.
The information provided here is a research-reference summary only. Elite AU Peptides makes no medical, therapeutic, cognitive, nootropic, or human-use claim about this product. Semax is not TGA-approved, is not a therapeutic good, and is supplied strictly for in-vitro and laboratory research use only. Researchers should consult the primary peer-reviewed literature for pathway data and protocol-specific reference values.
Reconstitute the lyophilised Semax vial with bacteriostatic water for laboratory handling. Add the diluent slowly down the vial wall and swirl gently rather than shaking. The required volume depends on the protocol’s downstream assay requirements — a 10 mg vial reconstituted in 5 mL of bacteriostatic water yields a 2 mg/mL working stock. Adjust per protocol.
Store the lyophilised powder at −20°C, desiccated and protected from light; once reconstituted, store refrigerated at 2–8°C and use within the documented research window, or aliquot and freeze to avoid repeated freeze-thaw cycles. Tamper-evident packaging; the batch label is the canonical reference for the certificate of analysis published in the lab-reports library.

- What is Semax?
- Semax is a synthetic heptapeptide — Met-Glu-His-Phe-Pro-Gly-Pro — a stabilised analogue of the ACTH(4-10) fragment, referenced across pro-cognitive, neurotrophic and neuropeptide research literature. The leading pro-cognitive nootropic peptide in research literature. Supplied strictly for in-vitro and laboratory research use only.
- How does Semax pair with Selank?
- Semax and Selank are the canonical "nootropic pair" in research literature — Semax framed as the pro-cognitive partner (BDNF / neurotrophic pathway research) and Selank as the anxiolytic / GABAergic partner. They are most frequently referenced together; see the Selank product page for the partner compound.
- Is Semax TGA-approved in Australia?
- No. Semax is not TGA-approved and is not a therapeutic good. We supply it strictly for in-vitro laboratory research use only and make no medical, cognitive, nootropic, or human-use claim about this product.
- Is this product third-party tested?
- Yes. Every batch is independently HPLC-tested by Janoshik, and the certificate of analysis is published on the lab-reports page.
- How should it be stored?
- Store the lyophilised powder at −20°C. Once reconstituted, keep it refrigerated at 2–8°C and use within the documented research window.
- How is it shipped?
- Dispatched AU-domestic from Australia. Free shipping over $100; orders placed before 12pm AEST are dispatched the same business day.
- What does 'research use only' mean?
- All products are supplied for in-vitro / laboratory research use only. They are not for human or animal consumption, are not therapeutic goods, and are not TGA-approved.
