Selank
Also known as: Anxiolytic peptide · Tuftsin analog
A synthetic heptapeptide analog of tuftsin studied for anxiolytic (calming) and immunomodulatory effects.
Selank is a synthetic heptapeptide developed from the endogenous immunopeptide tuftsin, with a proline-glycine-proline tail added to improve stability. It is one of the most-studied nootropic and anxiolytic research peptides.
Investigation focuses on its influence on GABAergic and monoamine signalling, on brain-derived neurotrophic factor (BDNF), and on immune modulation — the basis of its research interest for stress, mood and focus without the sedation associated with classical anxiolytics.
It is frequently studied alongside Semax, a related regulatory peptide. Supplied for research purposes only, HPLC-verified with a Certificate of Analysis.

Nootropic
A substance studied for supporting cognition — focus, memory, clarity — often via neurotrophic or neuroprotective pathways.
Peptide Bond
The covalent amide bond linking amino acids into a peptide chain — the defining structural feature of every peptide.
Half-Life
The time for a compound’s concentration to fall by half — a key determinant of dosing frequency in research.
Reconstitution
The process of dissolving a lyophilised (freeze-dried) peptide in a sterile solvent such as bacteriostatic water before study.
