Selank is a synthetic peptide developed for its potential effects on mood regulation, cognitive function, and stress response. It is a derivative of the naturally occurring tetrapeptide tuftsin and is studied for its unique ability to modulate the immune system and support neurotransmitter balance, particularly by influencing GABA activity. Researchers are exploring Selank for its potential anxiolytic (anti-anxiety), nootropic, and neuroprotective properties. This product is intended for research use only and is not for human consumption.
