Overview

A synthetic anxiolytic heptapeptide.

Selank is a synthetic analog of the tetrapeptide tuftsin, extended with a stabilizing Pro-Gly-Pro motif. It is studied primarily as an anxiolytic, with research examining its interaction with GABAergic and serotonergic signaling as well as its effects on immune-related cytokine expression.

Suria's Selank is synthesized to high purity and independently verified prior to release, supporting consistent results across behavioral and neuroendocrine research models.
