Description for Selank 5mg Peptide.

Selank 5mg – High-Purity Research Peptide

Selank is a synthetic peptide analogue of the naturally occurring immunomodulatory peptide tuftsin, investigated in preclinical research for its potential anxiolytic, neuroprotective, and cognitive-enhancing effects. Supplied as a lyophilised (freeze-dried) solid to preserve stability, this compound is verified at >99.1% purity (HPLC-tested) and provided with full Certificates of Analysis (COAs).

What is Selank?

Selank is a heptapeptide analogue derived from tuftsin, a natural peptide fragment involved in immune regulation. Research has examined Selank for its ability to modulate neurotransmitter systems, reduce anxiety without sedation, and support cognitive clarity. Unlike consumer supplements, Selank supplied by Bluewell Peptides is strictly intended for laboratory research use only and comes with full COA verification for transparency.

Research Applications of Selank

Preclinical and laboratory studies have investigated Selank for potential roles in:

• Anxiolytic Effects – Studied for its ability to modulate GABAergic and serotonergic pathways, reducing anxiety-like behaviours without sedation.

• Cognitive Support and Neuroprotection – Explored for its influence on memory, learning, and mental clarity, potentially linked to brain-derived neurotrophic factor (BDNF).

• Immune Modulation – Research suggests Selank may contribute to immune system regulation, particularly under stress or inflammatory conditions.
