EVIDENCE TAKEAWAY
The short answer.
DSIP's therapeutic reputation rests on very small historical studies and uncertain physiology, not on a modern clinical development program.
WHAT IS DSIP?
Start with identity.
A small endogenous research peptide associated with sleep physiology, with uncertain therapeutic relevance.
- Entity type
- Native peptide
- Research category
- Cognition
- Names and aliases
- DSIP · Delta sleep-inducing peptide
HUMAN VS PRECLINICAL
What evidence exists for DSIP?
Human sleep studies were tiny and conducted decades ago; they do not establish a modern therapeutic evidence base.
Historical laboratory research explored sleep and stress physiology, with unresolved questions about identity and mechanism.
