NA Selank amidate

N-Acetyl Selank Amidate (NA Selank Amidate) is a modified version of the nootropic peptide Selank. By adding an acetyl group (N-Acetyl) and an amide group to its structure, the peptide gains enhanced resistance to enzymatic degradation and better membrane permeability, prolonging its half-life and stability compared to the base peptide.
