Semax Australia

Semax Australia. Semax is a synthetic heptapeptide studied in laboratory research — Met-Glu-His-Phe-Pro-Gly-Pro, a stabilised analogue of the ACTH(4-10) fragment — referenced across the pro-cognitive, neurotrophic and neuropeptide research literature. The Elite AU Peptides Semax is independently HPLC-tested by Janoshik; the certificate of analysis is published on this page and in the lab-reports library, with the measured number and an independently verifiable Janoshik key.

Supplied in 10 mg lyophilised vials, AU-domestic, AUD pricing. Every batch is held until the independent HPLC report comes back within our acceptance threshold; nothing is listed without a certificate on file. 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.
