Selank is a peptide analog of tuftsin, researched for how it appears to influence GABAergic and other neurochemical signaling associated with calm and focus.
It is frequently studied alongside Semax — one framed more toward stimulation and cognition, the other toward calm focus — and shares the same Eastern-research heritage.
