Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP), identified by CAS number 129954-34-3. It is an analogue of tuftsin — an endogenous immunomodulatory tetrapeptide derived from the heavy chain of immunoglobulin G — extended at the C-terminus by the same Pro-Gly-Pro stabilising motif used in Semax, which substantially increases its resistance to enzymatic cleavage. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Selank has been characterised in preclinical anxiolytic research, where studies have investigated positive allosteric modulation of GABA-A receptor signalling alongside effects on serotonergic and noradrenergic turnover. Additional research has examined its influence on enkephalin degradation, interleukin and interferon expression, and BDNF levels in hippocampal tissue models, positioning it as a subject of interest at the intersection of neuropeptide and immunomodulation research. Supplied as a lyophilised white powder with a molecular weight of 751.9 Da and molecular formula C33H57N11O9. Supplied strictly for in-vitro laboratory research. Not for human or veterinary consumption.
Frequently Asked Questions
Is Selank legal to buy in Australia?
Selank is supplied strictly as a research chemical for in-vitro laboratory use. It is not approved for human therapeutic use in Australia and is not for human or animal consumption. Researchers are responsible for compliance with Therapeutic Goods Administration (TGA) regulations and their institution's protocols.
Is Selank third-party tested?
Yes. Selank is independently tested by Ozcanium Analytics, an independent Australian laboratory, at 99.17% purity by UPLC-MS/MS, analysed 28 August 2026 on lot 25/08/2026, net content 4.90 mg, verification code OZ-HPLCMS-TS02; bacterial endotoxin below 15.0 EU per vial by kinetic chromogenic LAL, analysed 28 August 2026, verification code OZ-ENDOTX-TPA5. The certificates are published in full on this page, and each verification code can be redeemed in the laboratory's own portal, so the document is confirmed against their records rather than ours.
What purity is Selank?
Selank is independently tested by Ozcanium Analytics at 99.17% purity by UPLC-MS/MS, analysed 28 August 2026. That is the laboratory's measurement of the lot it tested, not a figure of ours: Tested Peptides runs no analysis of its own.
Is there a Certificate of Analysis (COA) for Selank?
Yes. The Selank Certificate of Analysis is issued by Ozcanium Analytics, an independent Australian laboratory, and published in full at testedpeptides.com.au/certificates/selank. Testing is commissioned per compound and repeated periodically, and the current certificate replaces the last, so it is the most recent independent result for Selank rather than a test of every lot.
Where can I buy Selank in Australia?
Selank can be ordered here from Tested Peptides for in-vitro research use, dispatched same day from within Australia.
Do you provide dosing or administration guidance for Selank?
No. As these compounds are supplied for laboratory research only, we do not provide dosing or administration protocols. Our research library covers reconstitution and concentration calculations for in-vitro work.
