DSIP

Also known as: Delta Sleep-Inducing Peptide

Evidence Tier Bmed-high riskintermediatenot approved

Sleep-related peptide with human IV infusion studies showing sleep pressure effects. Mechanism uncertain.

Not Approved

This substance is not approved by any major regulatory body for human therapeutic use. All information is derived from preclinical research, limited clinical studies, or off-label contexts.

Overview

DSIP (Delta Sleep-Inducing Peptide) has uncertain biology and receptor targets, but human studies exist. IV infusions at 25 nmol/kg show reported sleep pressure effects. The evidence is older and mixed. Mechanistic certainty is low, and the contested biology increases the need for sourcing credibility.
