What it is and what it does

N-Acetyl Selank Amidate is Selank with an acetyl group added at one end and an amide at the other: modifications intended to slow enzymatic breakdown and extend duration. It is at an early stage, with no independent human trials of the variant yet, and it is not approved. It is commonly discussed for anxiety without sedation.
