Selank

Selank is described as a synthetic analog of the immunomodulatory peptide tuftsin, developed and studied in Russian clinical settings for anxiety-related conditions. The protocol frames its primary action as anxiolysis with an “anti-asthenic” profile—reducing anxiety while supporting energy and daytime function—without the sedation or dependence potential associated with benzodiazepines. While much of the published human literature uses intranasal administration, the page notes that subcutaneous administration can provide consistent absorption and straightforward measurement in research protocols. The mechanism section emphasizes clinical and preclinical observations: primate studies described elimination of fear/anxiety behaviors with lasting neurobehavioral stabilization, and rodent studies report efficacy comparable to classical tranquilizers. The overall “how it works” narrative is that Selank modulates anxiety circuitry in a non-sedating manner, supporting stress resilience and functional performance in research contexts.
