What is Selank?
Selank is a synthetic heptapeptide derived from tuftsin, a naturally occurring immunomodulatory tetrapeptide, extended with the same Pro-Gly-Pro stabilising tail used in Semax. The result is a molecule that retains tuftsin-associated activity but survives long enough in a research system to be studied usefully.
It is supplied as a lyophilized powder at 10 mg. See the reconstitution guide and the reconstitution calculator for preparation.
Research context
Selank is referenced in anxiolytic-model research, where studies examine its interactions with GABAergic and monoaminergic systems, and separately in immunomodulation work on cytokine expression. That dual character — a neuroactive peptide with an immune-peptide parent — is much of what makes it a compound of interest.
It is nearly always studied alongside Semax, its structural sibling from the same research programme, and appears near DSIP in designs concerned with stress-response and neuroendocrine regulation. On the immune side the comparators are Thymosin Alpha-1 and Thymalin.
Purity and third-party testing
Every batch is independently analysed by Testides and Peptide Test Canada and ships with a certificate of analysis reporting HPLC purity and mass-spectrometry identity. See how to read a certificate of analysis and what a purity figure actually means, or read about our testing on the Research and Quality page.
Handling and storage
Kept cold and protected from light in its lyophilized state; refrigerated once reconstituted. The storage guide covers both, and bacteriostatic vs. sterile water explains diluent choice — bacteriostatic water is stocked alongside.
