Selank
Selank is a synthetic heptapeptide derived from the endogenous immunomodulatory peptide tuftsin, with an added Pro-Gly-Pro sequence to enhance metabolic stability. It modulates BDNF and serotonin metabolism, producing anxiolytic effects without sedation or cognitive impairment. Selank is approved in Russia as a nasal spray for generalized anxiety disorder and has been studied for its nootropic and immunostimulatory properties.
