$89
Anxiolytic peptide analog of tuftsin that modulates GABAergic tone, stabilizes enkephalins, and reduces anxiety without sedation or dependence.
Overview
Selank is a synthetic heptapeptide analog of the endogenous immunomodulatory peptide tuftsin, developed at the Institute of Molecular Genetics in Moscow. Approved in Russia as an anxiolytic and nootropic, it reduces anxiety and improves stress resilience without the sedation, tolerance, or withdrawal associated with benzodiazepines. It simultaneously upregulates BDNF and modulates monoamine neurotransmitter systems.

Selank as an anxiolytic peptide
Semenova T.P. et al. — Bulletin of Experimental Biology and Medicine (2010)
Key FindingSelank produced anxiolytic effects comparable to diazepam in animal models without motor impairment, sedation, or tolerance development.
Effects of Selank on serotonin metabolism
Nadorova A.V. et al. — Doklady Biochemistry and Biophysics (2016)
Key FindingSelank normalized serotonin transporter gene expression and increased serotonin turnover in stressed rats.
Immunomodulatory and nootropic properties of Selank
Zozulya A.A. et al. — CNS Drug Reviews (2006)
Key FindingSelank exhibited dual anxiolytic and cognitive-enhancing properties in clinical trials, with an excellent tolerability profile and no withdrawal effects.
