Selank

Also known as: Tuftsin analogue

Evidence Tier B-Cmed-high riskintermediatenot approved

Tuftsin analogue peptide with anxiolytic/nootropic research and limited clinical GAD data.

FDA Safety Flag

The FDA has identified this substance as one that may present significant safety risks when used in compounding, including concerns about immunogenicity, impurity characterization, and/or insufficient safety information.

Not Approved

This substance is not approved by any major regulatory body for human therapeutic use. All information is derived from preclinical research, limited clinical studies, or off-label contexts.

Overview

Selank is a tuftsin analogue peptide with proposed neuroactive effects including allosteric modulation of the GABAergic system. A human GAD study reports intranasal administration of 2700 Âµg/day. Gene-expression changes consistent with complex neuroactive effects have been described. Limited Western regulatory framing; treat as higher scrutiny.
