Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide analog of the endogenous immunomodulatory tetrapeptide tuftsin (Thr-Lys-Pro-Arg), extended at the C-terminus with a stabilizing Pro-Gly-Pro tripeptide. It has been studied in cellular biology, neurobiology, and biochemical research literature examining GABAergic signaling, monoaminergic systems, neurotrophic factor expression (including BDNF pathways), cytokine modulation, and stress-response mechanisms in experimental models.
Each bottle contains 40mg of Selank in a ready-to-use spray formulation within a sealed 30mL bottle delivering approximately 200 metered sprays, verified through Mile High Compounds’ three-tier quality protocol: 7x independent third-party analytical testing, multi-unit batch conformity verification, and comprehensive heavy metal screening.

Research Background
Selank has been investigated in research literature across several scientific contexts:
GABAergic and anxiolytic pathway research — studies examining modulation of GABA-related signaling and adaptive behavioral responses in stress models
Neurotrophic factor pathway research — investigations into BDNF expression and related hippocampal signaling
Monoaminergic system research — studies on serotonin and catecholamine parameters in rodent models
Immunomodulatory and cytokine research — examination of interleukin and T-helper cell balance effects linked to its tuftsin-derived structure
Gene expression and cellular stress response research — transcriptomic and behavioral studies in experimental models of stress and hypoxia
Short-chain peptide chemistry and structure-activity research — analytical and comparative studies on tuftsin analogs and stabilizing Pro-Gly-Pro modifications
Selank is notable in research literature as a metabolically stabilized synthetic analog designed to retain the immunomodulatory and behavioral properties of tuftsin while enhancing resistance to enzymatic degradation. Foundational research is available through PubMed (pubmed.ncbi.nlm.nih.gov) and the National Institutes of Health’s PMC database (pmc.ncbi.nlm.nih.gov), where researchers can access peer-reviewed studies on Selank and related tuftsin/peptide research.
