Selank, also written Selank acetate, is a synthetic peptide derived from the immunomodulatory peptide tuftsin, studied for stress-response, calm-cognition, and GABAergic and serotonergic pathway research. It is a close companion to Semax in the brain-function family and is studied for how it engages the pathways associated with anxiety-response and neurotransmitter balance in preclinical models. The 10mg vial is the standard reference format, and researchers also study it in nasal-spray preparations.In animal and in-vitro research, Selank is investigated for its activity on GABAergic and serotonergic signalling and for stress-response and neuroimmune models. Its origin as a tuftsin analogue, a heptapeptide fragment with regulatory rather than hormonal activity, is the defining research characteristic and the reason it is studied as a stability-and-calm reference peptide.Selank is most often studied alongside Semax, the two are the paired reference nootropics in the range, investigated for complementary sides of focus and calm. Our how-to-choose-a-peptide library guide helps place compounds like these within a wider research plan, and the single-compound 10mg vial here is the clean reference format for Selank on its own.Every 10mg vial ships lyophilised with an independently verified batch certificate at a guaranteed floor of ≥98% purity, verifiable on the batch verification page using the batch number on the label. Reconstitute with bacteriostatic water: add it slowly down the inside wall of the vial, swirl gently, and never shake. Store the unopened vial at 2 to 8°C; refrigerate once reconstituted and do not refreeze. CAS reference 105726-95-0.Buying Selank in Australia is domestic: free Australia Post Express shipping to every state and territory, no minimum spend, dispatch from within Australia, and tracking on every parcel. Checkout accepts card, PayPal, or PayID, each vial is sealed under argon, and a 24-hour reservation holds your stock from order. Supplied strictly as a research material for lawful laboratory and in-vitro use, not for human or veterinary consumption.

- What is Selank?
- Selank is a tuftsin-derived heptapeptide studied for anxiolytic-pathway, stress-response, and nervous-system signalling. It belongs to the Brain Function family and is studied for its signalling activity in nervous-system and stress-response research. It is supplied as a lyophilised powder for in-vitro laboratory research purposes only, not for human use.
- Can I buy Selank at Chemist Warehouse in Australia?
- No. Selank is not available at retail pharmacies like Chemist Warehouse, Priceline, or any Australian pharmacy. It is a research compound not approved for human use by the TGA. Polaris Research supplies Selank exclusively as a lyophilised powder for in-vitro laboratory research.
- Can Australian compounding pharmacies supply Selank?
- Selank is not an approved commercial medicine and is not available as a compounded prescription product through Australian pharmacies. Polaris Research supplies research-grade Selank for lawful in-vitro laboratory research only, with independently verified batch certificates on every order.
- Where to buy Selank in Australia?
- Selank is available through Polaris Research with fast domestic Express Delivery to all Australian states and territories. Every vial is dispatched from within Australia, no customs delays, no international freight uncertainty. Each batch is independently third-party tested to ≥98% purity, with the Certificate of Analysis verifiable on our batch verification page.
- What is the cost of Selank in Australia?

- How do I reconstitute the vial?
- Reconstitute by adding Bacteriostatic Water slowly down the inside wall of the vial, never directly onto the powder. Swirl gently to dissolve; do not shake. Once reconstituted, keep the solution refrigerated and avoid repeated freeze-thaw cycles. For a step-by-step walkthrough, see our Peptide Reconstitution Guide.
- How should I store it?
- Store the unopened lyophilised vial refrigerated at 2–8°C, kept dark and upright. Once reconstituted, keep the solution refrigerated and use it within a few weeks. Never re-freeze a reconstituted solution, ice crystals damage the compound. A clear, particle-free liquid is the sign of a clean reconstitution.
