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.
Safety and Side Effects
Limited old safety data; unregulated product quality applies.
Frequently Asked Questions
