Selank is a synthetic heptapeptide developed in Russian neuropeptide research, derived from the endogenous regulatory peptide tuftsin. In research it is studied for anxiolytic-like, immunomodulatory, and neurotrophic mechanisms in rodent models. Supplied strictly for Research Use Only.
Selank is studied in preclinical research on GABAergic neurotransmission, BDNF expression, immune cytokine modulation, and anxiety-related behavioral models in rodents. All cited studies are conducted in rodent or in-vitro systems consistent with RUO classification.
Selank and semax are both synthetic Russian-developed neuropeptides but with different sequences and target profiles. Semax is derived from ACTH(4-10) and primarily studied for nootropic and neuroprotective mechanisms. Selank is derived from tuftsin and primarily studied for anxiolytic-like and immunomodulatory mechanisms in research models.
