Selank is a synthetic analog of the naturally occurring immunomodulatory peptide Tuftsin (Thr-Lys-Pro-Arg), with an additional Gly-Pro sequence appended to enhance stability and bioavailability. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Selank has been extensively studied for its anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) properties. Research demonstrates that Selank modulates GABA, serotonin, and dopamine systems without sedation or addiction potential. It also shows immunomodulatory effects by influencing interleukin and interferon expression. Available as a lyophilized powder or in nasal spray-ready formulations for research and wholesale distribution.
