SELANK SPRAY

Selank Spray 40mg

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.

Analytical Verification

Every batch undergoes Mile High Compounds’ comprehensive analytical protocol:

• High-Performance Liquid Chromatography (HPLC) for purity quantification
• Mass Spectrometry (MS) for molecular weight and identity confirmation
• 14-day sterility testing
• Endotoxin analysis
• Multi-unit batch conformity verification — statistically robust consistency testing across each production batch, exceeding the industry-standard single-unit sampling approach
• Heavy metal screening for lead, arsenic, cadmium, mercury, and additional trace metals
• Container and seal integrity verification

Batch-specific Certificates of Analysis (COAs) accompany every order, documenting full testing results across all verification protocols.

Storage and Handling

• Storage: Cool, dry location away from direct light; refrigerate at 2-8°C for optimal stability
• Protect from light and excessive heat
• Avoid: Freezing or prolonged exposure to elevated temperatures to preserve compound stability and solution integrity
• Use within the labeled period after first opening for optimal research integrity
