Selank – 5mg

Selank is a synthetic heptapeptide analogue of Tuftsin, developed by the Institute of Molecular Genetics of the Russian Academy of Sciences with several decades of documented research into its anxiolytic, nootropic, and immunomodulatory activity profile. iLab Pharma’s 5mg lyophilized vial delivers a lower concentration presentation than the iLab Pharma 10mg Selank vial, suited to researchers requiring precise low dose titration capability, initiating dose response characterization studies at the lower end of the Selank concentration spectrum, or conducting shorter duration protocols where the 10mg supply exceeds compound volume requirements.

The 5mg injectable vial format occupies a distinct research position from the Hudson Science 5mg nasal spray at equivalent concentration. Both deliver 5mg total Selank but through fundamentally different administration routes: the nasal spray’s intranasal delivery provides proximity to the olfactory epithelium and potential direct CNS access via the olfactory nerve pathway, a pharmacokinetically relevant advantage for a centrally acting neuropeptide facing blood brain barrier permeability limitations via peripheral administration. The lyophilized injectable vial supports parenteral administration routes and in vitro research applications where precise solution concentration preparation is a critical variable. Enabling comparative bioavailability studies between intranasal and injectable delivery routes that matched concentration across both formats makes particularly practical.

Selank’s anxiolytic mechanism operates through indirect GABAergic modulation alongside documented influence on BDNF expression. Distinguishing it from classical benzodiazepine anxiolytics that produce sedation and dependence through direct GABA-A receptor binding. This non sedating anxiolytic mechanism combined with BDNF mediated neuroplasticity effects and the Tuftsin derived immunomodulatory characteristics spanning innate immune regulation and macrophage activation pathways makes Selank a dual focus research compound across neuropharmacology and immunology literature.

iLab Pharma formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range. Each batch is tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD stocks Selank across three formats: this iLab Pharma 5mg lyophilized vial, the iLab Pharma 10mg lyophilized vial, and the Hudson Science 5mg nasal spray. Giving researchers concentration and delivery route flexibility from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
