Selank
Selank (TP-7) exhibits anxiolytic and mild cognitive-enhancing effects via GABAergic modulation and BDNF upregulation in rodent studies. Typically dosed intranasally at 250–750 mcg/day in research protocols. Shown to reduce anxiety-related behaviour without impairing motor function in preclinical models.
