Buy Selank Research Peptide UK | 99%+ Purity

Selank (sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide analogue of the endogenous immunomodulatory peptide tuftsin, developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is studied for its role in GABA-A receptor modulation, serotonergic and dopaminergic signalling, and anxiolytic-like mechanisms in laboratory research models.

Selank exhibits improved metabolic stability over endogenous tuftsin, with preclinical research exploring its interaction with multiple neurotransmitter systems. It is commonly used in laboratory investigations of stress response, memory consolidation, and neurological resilience pathways, including work on cytokine profiles and neuroimmune signalling.
