DSIP (Delta Sleep-Inducing Peptide)

A nonapeptide isolated in the 1970s from rabbit brain during induced sleep. Decades of small studies have produced inconsistent results.

Overview

DSIP (Delta Sleep-Inducing Peptide) is catalogued here as a sleep-associated nonapeptide and graded at the "Minimal evidence" evidence tier. There is little or no formal study of this compound. Claims rest on anecdote, theory, or very early-stage work; risk data are absent by definition.

A nonapeptide isolated in the 1970s from rabbit brain during induced sleep. Decades of small studies have produced inconsistent results.

Mechanism of Action

Proposed mechanisms involve modulation of sleep architecture and stress-response systems; the physiological role of endogenous DSIP-like material remains unsettled.

Research and Evidence

Small human studies from the 1980s–90s reported mixed effects on sleep and insomnia; no modern controlled trials exist.

Evidence in context: the Neuro, Nootropic, and Cosmetic Peptides class page collects the shared evidence themes and study-reading guidance for this category.

Safety and Side Effects

Limited old safety data; unregulated product quality applies.

Educational notice: this entry describes published research and, where they exist, regulator labels. It is not medical advice and not a recommendation for use. Research-grade compounds have no verified human-safety data.
