Selank

A tuftsin-derived heptapeptide that delivers benzodiazepine-level anxiety relief without sedation, dependence, or cognitive fog — while simultaneously boosting immune defence.

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) engineered from the immune peptide tuftsin. It allosterically modulates GABA-A receptors, stabilises endogenous enkephalins, and upregulates BDNF — delivering anxiolysis, cognitive enhancement, and immunomodulation in a single molecule.
