Delta Sleep Inducing Peptide (DSIP) is a naturally occurring neuropeptide originally isolated from rabbit cerebral venous blood in 1974 by Swiss researchers studying sleep induction. One of the earliest endogenous peptides identified through sleep research, with a documented investigation history spanning five decades of neuropharmacological literature. Hudson Science’s 10mg formulation supplies a higher concentration standalone vial presentation compared to CSD’s Hudson Science DSIP 5mg nasal spray, providing researchers requiring larger compound availability or parenteral administration routes with a practical lyophilized vial format suited to reconstitution based research protocols.

The 10mg lyophilized vial and 5mg nasal spray serve distinct research purposes within CSD’s DSIP range. The nasal spray format’s intranasal delivery provides proximity to the olfactory epithelium and potential direct CNS access via the olfactory nerve pathway; a pharmacokinetically relevant route for a centrally acting neuropeptide facing blood brain barrier permeability limitations via peripheral administration. The lyophilized vial format supports parenteral administration routes and enables precise solution concentration preparation for in vitro research applications, comparative bioavailability studies between intranasal and injectable delivery, and protocols requiring higher dose point evaluation beyond the 5mg nasal spray supply capacity.

DSIP’s research profile extends considerably beyond its original sleep induction characterization. The peptide has accumulated investigation across hypothalamic pituitary axis activity modulation, corticotropin and LH release regulation, stress response attenuation, and antioxidant activity in neuronal tissue. With DSIP receptors identified across multiple brain regions including the hypothalamus, limbic system, and cortex suggesting a broad neuromodulator role. This distributed receptor presence and multi pathway activity profile has made DSIP a frequently studied reference compound in research examining endogenous neuropeptide signaling across sleep, stress, and neuroendocrine regulation pathways simultaneously.

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 DSIP across two formats, this 10mg lyophilized vial and the 5mg nasal spray. Giving researchers delivery route and concentration flexibility from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.

Reconstitute with bacteriostatic water prior to use. Store lyophilized peptide at 2–8°C away from direct light. Once reconstituted refrigerate and use within 28 days. Intended for research purposes only.
