N-Acetyl Selank is an acetylated derivative of the heptapeptide Selank, engineered for greater stability and better oral/intranasal absorption.

Mechanism — Modulates GABA, BDNF, and serotonin signaling. The acetyl group resists peptidase degradation, enabling effective non-injectable delivery (nasal spray, sublingual). Anxiolytic, mildly nootropic, immunomodulatory.

Use case — Daytime anxiety without sedation, social and performance situations, cognitive support during stress. Typical nasal dosing 200-400 mcg/day in divided doses.

Caveats — Investigational; Selank itself is approved only in Russia. Stack carefully with other GABAergics. Tolerance is reported with daily use over months.
