Selank is a synthetic heptapeptide analogue of the endogenous immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg-Pro-Gly-Pro), developed for its nootropic and anxiolytic properties. Research has examined its role in modulating GABA-A receptor activity, upregulating BDNF expression, and attenuating hypothalamic-pituitary-adrenal (HPA) stress responses — without the sedating profile associated with classical anxiolytics. Studies have also explored its immunomodulatory effects via enkephalin system modulation. Each vial is lyophilized, independently tested for identity, purity, and quantity, and shipped with its batch COA number printed on the label. For research purposes only.
Storage & handling +
Store lyophilized vials refrigerated (2–8°C), protected from light and moisture. After reconstitution with bacteriostatic water, keep refrigerated and use within the recommended window. Avoid repeated freeze-thaw cycles.
Shipping & returns +
Orders placed before the daily cutoff ship the next business day via Canada Post Express (1–3 business days anywhere in Canada). Discreet packaging with no product labeling on the outer box.

"Selank arrived in 2 days to Calgary. COA verified, reconstituted cleanly. Really noticeable effect on stress response in my research protocol — exactly what I was looking for."
