About DSIP (Delta Sleep-Inducing Peptide)
DSIP is a nonapeptide, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, isolated by Schoenenberger and Monnier from the cerebral venous blood of rabbits in which slow-wave (delta) sleep had been induced by electrical stimulation. It was named for its reported ability to promote delta-wave sleep when transferred to other animals.
No dedicated gene or specific receptor for DSIP has been conclusively identified, and its physiological role is still debated.
Research context
DSIP is used in research on sleep regulation, stress-related neuroendocrine responses and neuropeptide pharmacology in animal models. Because results in the literature are inconsistent, it is often studied alongside better-characterized neuropeptides.

DSIP (Delta Sleep-Inducing Peptide): frequently asked questions
Does DSIP have a known receptor?
Not conclusively. Despite decades of study, a specific DSIP receptor has not been identified, which is one reason its mechanism remains unclear.
Which DSIP (Delta Sleep-Inducing Peptide) presentations are listed?
2 presentations are listed: 5 mg (DS5), 10 mg (DS10). Each is packed 10 vials per box, and every presentation has its own specification page and product code.
How do I request a quote for DSIP (Delta Sleep-Inducing Peptide)?
Open the presentation you need and use Ask price to message PureForm Biosciences on WhatsApp, or add several materials to the inquiry cart and send them together. Pricing, current availability and lot documents are confirmed in that conversation.
