Selank Australia

Selank Australia. Selank is a synthetic heptapeptide studied in laboratory research — Thr-Lys-Pro-Arg-Pro-Gly-Pro, a stabilised analogue of the immune-research tetrapeptide tuftsin — referenced across the anxiolytic, GABAergic-modulation and neuropeptide research literature. The Elite AU Peptides Selank 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.

Selank (CAS 129954-34-3; molecular formula C33H57N11O9, average molecular weight ≈ 752 g/mol; sequence TKPRPGP) is a synthetic heptapeptide derived from the immune-research tetrapeptide tuftsin (Thr-Lys-Pro-Arg), extended at the C-terminus with a Pro-Gly-Pro stabilising motif. It is referenced as the leading anxiolytic nootropic research peptide — distinct from the pro-cognitive Semax in the same nootropic-pair framing.

Its neurotrophic activity was reported by Inozemtseva and colleagues (Doklady Biological Sciences, 2008), who found intranasal Selank raises hippocampal BDNF (brain-derived neurotrophic factor) mRNA and protein in research models — indicating local neurotrophin induction.

Its GABAergic mechanism was characterised by Volkova and colleagues (Frontiers in Pharmacology, 2016), who reported that Selank alters the expression of genes involved in GABAergic neurotransmission — a molecular basis for the anxiolytic-pathway research the compound is referenced in.

Selank is most frequently studied alongside Semax — the two form the canonical "nootropic pair" in research literature, Selank framed as the anxiolytic / GABAergic partner and Semax as the pro-cognitive partner. See the Semax product page for the pro-cognitive partner.

The information provided here is a research-reference summary only. Elite AU Peptides makes no medical, therapeutic, anxiolytic, nootropic, or human-use claim about this product. Selank 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 Selank 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.
