Selank 5mg
Selank is a synthetic heptapeptide analogue of the naturally occurring immunomodulatory peptide tuftsin. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Selank combines the Thr-Lys-Pro-Arg sequence of tuftsin with an additional Pro-Gly-Pro stabilising sequence.
Research into Selank has focused on two primary domains: anxiolytic activity and cognitive modulation. Preclinical studies have investigated its effects on GABAergic neurotransmission, serotonin metabolism, and brain-derived neurotrophic factor (BDNF) expression. The peptide has shown particular promise in studies examining stress response modulation without sedative side effects.
Selank has also been studied for its immunomodulatory properties, inherited from its tuftsin-derived structure. Research has documented effects on cytokine balance, T-helper cell ratios, and inflammatory marker regulation. This dual anxiolytic-immunomodulatory profile makes it a unique research tool.

Where can a laboratory buy Selank in the EU?
Onyx Peptides supplies Selank for laboratory research across the European Union. We are operated by Vexio j. s. a. (IČO 54214530) in Slovakia and dispatch from within the EU, so there is no customs entry, no import duty and no border hold. Orders placed before 16:00 CET ship the same day, and shipping is free above €100.
How do I verify the batch of Selank I receive?
Each vial carries a batch number. Ask us for the Certificate of Analysis of the batch currently in stock — before you order, not after — and check that the batch number on the certificate matches the one printed on the vial. The analysis is performed by Janoshik Analytical, an independent laboratory in Prague, which will confirm a report it issued if you contact them with its identifier.
How is purity verified?
Every batch is independently tested by Janoshik Analytical using HPLC and Mass Spectrometry. A batch-specific Certificate of Analysis — also covering endotoxins and heavy metals — is available on request.
How fast is delivery?
We dispatch from within the EU, same day on orders placed before 16:00 CET. EU delivery typically takes 1–3 business days.
What payment methods do you accept?
We accept SEPA bank transfer (−2 %), cryptocurrency (−5 %), cash on delivery (+€1.50). Bank-transfer orders are dispatched as soon as the payment clears; SEPA instant transfers usually arrive within seconds.
How should this be stored?
Store at 2–8 °C, protected from light. Once reconstituted, keep refrigerated and use within 30 days.
What is the intended use?
All products are supplied strictly for in-vitro laboratory and research use only. They are not for human consumption, veterinary, or clinical use.
