Selank: an anxiolytic research peptide

Selank is a synthetic peptide derived from the immunomodulatory peptide tuftsin, widely studied in the research literature for its effects on the central nervous system. It is frequently investigated as a model compound in anxiolytic and behavioural research.

Origins and structure

Selank is a short synthetic peptide developed from tuftsin, a naturally occurring fragment associated with immune signalling. Researchers were drawn to it because small peptides can be modified for greater stability while retaining activity in laboratory models. Its relatively simple sequence makes it a convenient tool for studying peptide behaviour in neurological research.

What researchers study

In preclinical models, Selank is examined for its role in pathways connected to anxiety-related behaviour, stress response, and neurotransmitter balance, including GABAergic and monoamine systems. Some research also explores its association with brain-derived neurotrophic factor expression. These studies are exploratory and describe activity in controlled models, not outcomes in humans.

Handling and documentation

Selank ships as a lyophilised powder reconstituted with bacteriostatic water before use, and every Vela order includes a free 3 mL bacteriostatic water vial; our reconstitution guide explains the process. Every batch ships with a certificate of analysis confirming identity and purity, and reconstituted peptide is generally kept refrigerated and protected from light.
