Selank 5mg

Intended for laboratory research purposes only. Not for human consumption

Selank is a synthetic heptapeptide analog of the naturally occurring immunomodulatory tetrapeptide tuftsin. It is a regulatory peptide developed for research into anxiolytic, nootropic, and neuroprotective effects, with modifications that enhance metabolic stability compared to native tuftsin.
