Selank 5mg: Nootropic Peptide

Selank is a synthetic heptapeptide based on the immunomodulatory peptide tuftsin. It is widely studied for its effects on anxiety-related pathways, cognitive function, BDNF expression, immune modulation, and central nervous system regulation.

Selank is often classified as a nootropic and anxiolytic research peptide due to its influence on neurological and behavioral pathways in experimental models.

Scientific Background

Selank was engineered by modifying the natural tetrapeptide tuftsin and extending it to a stable seven–amino-acid peptide.
Research indicates that Selank may influence:

• GABAergic activity

• Serotonin modulation

• BDNF (Brain-Derived Neurotrophic Factor) expression

• Immune–nervous system interactions

• Stress-adaptation pathways

• Cognitive performance markers

Unlike benzodiazepines, Selank does not appear to affect GABA receptors directly in the same manner, making it a unique molecule for neurobehavioral studies.
