Selank or selanc is a synthetic heptapeptide analog of the  endogenous tetrapeptide tuftsin, with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. This synthetic variant of immunomodulatory tetrapeptide tuftsin possesses anxiolytic properties because of its mimic nature. Among this peptide’s positive characteristics, are its ability to induce serotonin’s metabolic processes and affect the concentration of specific monoamine neurotransmitters. Some scientists believe that Selank possesses such modulatory feature as influencing expression of brain-derived neurotropic factor. Buy Selank of high quality only at Research Liquids.
