Selank is derived from tuftsin, a peptide the immune system makes. It is studied for its effect on GABA signaling, the brain's main calming system, and on the balance of stress-related neurotransmitters including serotonin.
Unlike sedatives, Selank is studied for reducing anxiety without drowsiness, slowed thinking, or dependence. Research has also looked at its effect on BDNF and on the stress hormone system.
