TOPIC OVERVIEW
About DSIP
Identity and names
DSIP expands to delta sleep-inducing peptide and is also associated with the name emideltide. The name describes a research history rather than a proven sleep benefit.
Compound type
DSIP is a short peptide studied in neurophysiology. Preparation, route, and experimental conditions are important when comparing studies.
Mechanism
Research addresses sleep-wake regulation and related physiological responses. Its mechanism and effects cannot be summarized as a universally reliable sleep switch.
Research focus and evidence
Historical human studies were small and used defined laboratory conditions. Contemporary consumer claims can exceed what those studies establish.
Regulatory status and limits
Historical clinical experiments do not amount to approval of research-market DSIP. Human safety, preparation quality, and route-specific evidence need assessment.
Topics covered
- sleep-wake research
- historical human trials
- mechanistic uncertainty
- preparation and safety
Common names and related terms: DSIP, Delta sleep-inducing peptide, Emideltide
RESEARCH SUMMARY
What Is DSIP?
LAST VERIFIEDOctober 7, 2026
A placebo-controlled, double-blind study evaluated DSIP in 14 people with severe chronic insomnia over a short treatment period. Its size and duration limit conclusions about routine or long-term use. Schneider-Helmert, chronic-insomnia study
An earlier open study in seven patients investigated repeated DSIP administration. Without a blinded comparison, reported changes cannot by themselves establish a dependable treatment effect. Historical open DSIP clinical study

How to interpret this profile
Registry and publication counts describe discoverable records, not proof of effectiveness or safety. Study design, compound identity, population, endpoints, and regulatory context must be reviewed individually.
