Overview
Selank is a synthetic analog of the immunomodulatory peptide tuftsin. It was developed in Russia and is approved there as an anxiolytic. In the US it is not FDA-approved. Its nomination was withdrawn from the FDA’s Category 2 list in September 2024 (as Selank Acetate/TP-7). That withdrawal does not create a legal compounding pathway—Selank remains unapproved in the US. It has been studied for anxiety, cognitive enhancement, and immune modulation, with clinical studies primarily in Russia. People in the US should not assume it is legally available; evidence and legality are both uncertain stateside.
How It Works (Mechanism of Action)
Selank is thought to modulate anxiety and immune function through effects on neurotransmitters and immune pathways. Russian research has characterized some mechanisms; US data are limited.
