DSIP Delta Sleep-Inducing Peptide
For in vitro research use only. DSIP is not for human or veterinary consumption, diagnosis, treatment, or prevention of any condition.
DSIP is a short neuropeptide (a type of small protein used for signalling between brain cells) made up of just 9 amino acids. It was first isolated from rabbit blood during deep sleep. Animal studies have investigated how it interacts with the structure of sleep - particularly the deep, slow-wave stages - and how it affects the body's stress-response systems.

Research overview
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. It was first isolated from the cerebral venous blood of rabbits in 1977 by Schoenenberger and Monnier, following electrical stimulation of the thalamus during sleep induction experiments — giving rise to its name. Unlike most synthetic peptide research compounds, DSIP is an endogenous neuropeptide identified in the hypothalamus, limbic system, pituitary, and peripheral tissues of mammals, though it is supplied here as a synthesised research reagent for controlled experimental conditions.
The primary area of research interest for DSIP has been sleep regulation and neuroendocrine modulation. Early rodent studies reported that peripheral and central administration of DSIP modified slow-wave and delta sleep patterns, though subsequent research has produced variable results and the precise mechanism by which DSIP interacts with sleep architecture remains an active area of investigation. Separately, research has examined DSIP’s role in stress axis modulation — specifically its effects on corticotropin-releasing hormone (CRH) and ACTH secretion — suggesting a potential interface between the sleep regulatory system and the hypothalamic-pituitary-adrenal (HPA) axis.
DSIP has also been studied for antioxidant properties and neuroprotective potential in cell culture models, and for its interaction with opioid peptide systems and basal ganglia function. Its relatively small, stable nonapeptide structure makes it a practical tool for studying receptor binding kinetics and neuroendocrine signalling in vitro. Velox Peptides supplies DSIP at ≥99% HPLC-verified purity as a lyophilised research reagent for in vitro use by qualified researchers. Not for human or veterinary consumption.

Is DSIP legal to buy in the UK?
Yes. Research peptides including DSIP are lawful to purchase in the United Kingdom strictly for legitimate in vitro scientific research purposes. They are not controlled substances under UK law and are not subject to prescription requirements when purchased for research use. Velox Peptides supplies DSIP solely as a research reagent to qualified researchers. Buyers are responsible for ensuring all use complies with applicable law and with Velox Peptides’ Research Use Policy.
Where and when was DSIP first isolated, and what does its name refer to?
DSIP (Delta Sleep-Inducing Peptide) was first isolated from the cerebral venous blood of rabbits in 1977 by researchers Schoenenberger and Monnier at the University of Basel, following experiments in which the thalamus was electrically stimulated to induce sleep. The name refers to its observed association with delta (slow-wave) sleep in initial animal studies. DSIP has the amino acid sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (nine residues, making it a nonapeptide) and CAS number 62568-57-4. It is found endogenously in several mammalian tissues including the hypothalamus and pituitary.
