What Is Selank?

Classification and structure

Selank is a synthetic heptapeptide based on tuftsin, a short naturally occurring peptide fragment with described immunomodulatory activity. Structural modifications are intended to improve its stability relative to native tuftsin, and in the literature it is grouped with the neuropeptide research compounds.

Mechanism studied in research

Selank has been examined in several research contexts, primarily in animal models:

• Neuropeptide signalling — studied as a stabilised tuftsin analogue.
• Stress-related behaviour — examined in animal-model studies.
• Neurotrophin expression — investigated in relation to brain-derived neurotrophic factor (BDNF) in the brain.

Published research characterises these effects in laboratory and animal-model systems.

These statements describe the published scientific record; they are not claims about any effect in humans.

Research background

Selank was developed from research on tuftsin and related short peptides and has since been studied in neuropeptide and neurotrophic-signalling research, largely in animal models. As an investigational compound it remains a subject of ongoing study. Findings are reported in the primary scientific literature listed below.

Purity, testing and handling

Lazarus Labs supplies Selank as a lyophilised (freeze-dried) reference material, independently tested to 99%+ purity, with a batch Certificate of Analysis (COA) available. Lyophilised peptides are typically stored cold and protected from light, in line with standard laboratory practice for reference materials.
