DSIP
Delta Sleep-Inducing Peptide — a neuropeptide studied for its association with slow-wave sleep and stress-axis signaling.
Overview
DSIP is a naturally occurring neuropeptide first isolated from rabbit brain tissue in the 1970s, named for its association with delta-wave (slow-wave) sleep activity observed in early animal studies. It has since been studied more broadly in the context of neuroendocrine regulation.
Mechanism of Action
Research suggests DSIP may interact with the hypothalamic-pituitary-adrenal (HPA) axis, the body’s central stress-response system, and has been studied for potential effects on stress-hormone regulation (such as cortisol) alongside its originally observed association with sleep architecture. Its precise receptor target has not been definitively established in the published literature.
Cited Research

Safety & Handling
DSIP should be handled only by qualified personnel in a laboratory setting, stored and reconstituted per its Certificate of Analysis, and kept refrigerated once reconstituted. It is not evaluated or approved by the FDA for any human or veterinary use.
Frequently Asked Questions
Is DSIP legal to purchase?
It’s legal to sell and purchase as a research chemical for laboratory use in the U.S. It is not approved by the FDA as a drug or supplement for human consumption.
How should DSIP be stored?
Keep the lyophilized powder refrigerated or frozen prior to reconstitution. Once reconstituted, keep refrigerated and use within the timeframe on its Certificate of Analysis.
Does DSIP directly induce sleep?
Its name reflects the original 1970s research context, not a confirmed mechanism. Later research has focused as much on stress-axis signaling as on sleep itself, and the compound’s full mechanism remains an active research question.

No. This page summarizes published literature for research and educational context only. It does not recommend a dose, protocol, or use in humans or animals outside a laboratory setting.
