Selank anxiolytic research peptide vial — 10mg, independently HPLC-tested, COA on file

[ Research use only · Not for human consumption ]

Selank in Australia. Selank is a synthetic heptapeptide — Thr-Lys-Pro-Arg-Pro-Gly-Pro, a stabilised analogue of the immune-research tetrapeptide tuftsin — referenced across anxiolytic, GABAergic-modulation and neuropeptide research literature, and the leading anxiolytic nootropic research peptide. This guide is a research-reference summary for Australian researchers; it makes no anxiolytic or human-use claim.

What Selank is

Selank is 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 framed as the anxiolytic counterpart to the pro-cognitive Semax within the nootropic-pair literature — the same structural stabilisation strategy, applied to a different parent peptide and a different research strand.

The GABAergic and neurotrophic mechanisms

Selank’s 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. 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 — the molecular basis for the anxiolytic-pathway research the compound is referenced in. It is studied in vitro as a research tool, not as a treatment.

Selank and Semax: the nootropic pair

Selank is most frequently studied alongside Semax — the two form the canonical “nootropic pair” in research literature, Selank the anxiolytic / GABAergic partner and Semax the pro-cognitive partner. See the Semax vs Selank comparison for the distinction and the Semax guide for the partner compound.

Identity, purity and handling

Every batch of Selank is independently HPLC-tested by Janoshik before it is listed, with the certificate published on the product page and in the lab-reports library — real batch number, measured percentage, independently verifiable at janoshik.com. Reconstitute with bacteriostatic water; store the powder at −20°C and, once reconstituted, at 2–8°C. Selank is not TGA-approved and is not a therapeutic good — supplied strictly for in-vitro and laboratory research use only, with no anxiolytic or human-use claim.

[ Frequently asked ]

Nootropic research — questions researchers ask.

What is Selank?
Selank is a synthetic heptapeptide — Thr-Lys-Pro-Arg-Pro-Gly-Pro, a stabilised analogue of the immune-research tetrapeptide tuftsin — referenced across anxiolytic, GABAergic-modulation and neuropeptide research literature; the leading anxiolytic nootropic research peptide. Elite AU Peptides supplies it strictly for in-vitro and laboratory research use only — not for human or animal consumption, not a therapeutic good, and not TGA-approved. No anxiolytic or human-use claim is made about it.
What research is Selank associated with?
Its neurotrophic activity was reported by Inozemtseva and colleagues (Doklady Biological Sciences, 2008), who found intranasal Selank raises hippocampal BDNF mRNA and protein in research models. Its GABAergic mechanism was characterised by Volkova and colleagues (Frontiers in Pharmacology, 2016), who reported it alters the expression of genes involved in GABAergic neurotransmission. It is studied in vitro as a research tool, not as a treatment.
How does Selank pair with Semax?
Selank and Semax are the canonical “nootropic pair” in research literature — Selank framed as the anxiolytic / GABAergic partner and Semax as the pro-cognitive partner. They are most frequently referenced together; see the Semax guide or the Semax vs Selank comparison for the distinction.
Is Selank TGA-approved in Australia?
No. Selank is not TGA-approved and is not a therapeutic good. It is supplied strictly for in-vitro and laboratory research use only, with no medical, anxiolytic, or human-use claim.
How is research-grade Selank tested?
Every batch is independently HPLC-tested by Janoshik Analytical before it is listed. The measured purity is published on the product page and in the lab-reports library — real batch number, measured percentage, independently verifiable at janoshik.com; nothing is listed without a certificate on file.
How is Selank reconstituted, stored and shipped?
Reconstitute the lyophilised vial with bacteriostatic water — a 10mg vial in 5mL yields a 2mg/mL working stock. Store the powder at −20°C protected from light; once reconstituted, refrigerate at 2–8°C. Dispatched AU-domestic, free shipping over $100, same-day dispatch before 12pm AEST. Supplied strictly for laboratory research use only.
