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. Hudson Science’s 20mg nasal spray delivers 333mcg per metered spray actuation; a significantly higher total compound and per actuation concentration than CSD’s existing Hudson Science Selank 5mg nasal spray at 50mcg per spray, providing a four fold increase in total compound supply and a six fold increase in per spray dose suited to research protocols requiring higher concentration Selank administration or extended supply continuity from a single unit.
The 20mg and 5mg Selank nasal spray presentations serve distinct research purposes within CSD’s Selank nasal delivery range. The 5mg format at 50mcg per actuation provides the most granular low dose titration capability, suited to initial dose response characterization, conservative entry into Selank research, and protocols examining anxiolytic and nootropic activity at the lower end of the concentration spectrum. The 20mg format at 333mcg per actuation addresses mid to upper range concentration research, extended protocol timelines requiring substantial compound supply from a single unit, and dose response studies examining Selank’s GABAergic, BDNF, and immunomodulatory activity at higher concentration points that would exhaust the 5mg format’s supply rapidly.
The intranasal delivery route remains the most pharmacokinetically relevant administration format for Selank regardless of concentration, the nasal mucosa’s proximity to the olfactory epithelium provides potential direct CNS access via the olfactory nerve pathway, bypassing blood brain barrier limitations that complicate peripheral administration of centrally acting neuropeptides. This CNS access advantage is particularly relevant for Selank’s primary research targets in hypothalamic, limbic, and cortical structures where its GABAergic modulation, BDNF upregulation, and Tuftsin derived immunomodulatory activity have been documented across decades of Russian and international investigation.
Hudson Science 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 20mg nasal spray, the 5mg nasal spray, the iLab Pharma 5mg lyophilized vial, and the iLab Pharma 10mg lyophilized vial, giving researchers complete concentration, delivery route, and supply volume flexibility from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Store at 2–8°C away from direct light. Do not freeze. Keep upright. Intended for research purposes only.
