Selank is a synthetic heptapeptide analog of tuftsin, an endogenous immunomodulatory tetrapeptide. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences (the same institution behind Semax), Selank has been used clinically in Russia for generalized anxiety disorder and phobias since the early 2000s.

How It Works

Unlike benzodiazepines and other conventional anxiolytics, Selank does not act on GABA receptors and carries no risk of dependence, tolerance buildup, or withdrawal. Its mechanism involves modulation of BDNF expression, stabilization of enkephalins (endogenous opioid peptides), and regulation of the serotonin and dopamine systems.

Selank is notable for combining anxiolytic and nootropic effects simultaneously - reducing anxiety while simultaneously improving cognitive clarity, memory consolidation, and focus. This dual profile makes it popular among individuals seeking calm alertness without sedation.
