DSIP (Delta Sleep-Inducing Peptide)
Peptide ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
DSIP is a nonapeptide historically investigated for sleep regulation and stress physiology. It is not FDA-approved, and controlled human insomnia studies are small and inconsistent. It should not be used as a substitute for evidence-based insomnia evaluation, sleep apnea diagnosis, or approved sleep therapies.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
DSIP (Delta Sleep-Inducing Peptide) is a peptide most often used for small studies in chronic insomnia, stress and sleep architecture research interest, no approved sleep indication. NutriStack rates the overall evidence as insufficient. A typical adult dose is No FDA-approved human dose; older studies used protocol-specific injections, commonly taken as not recommended outside approved research. This profile indexes 3 sources.
The bottom line
Evidence rating insufficient. Most-documented uses: small studies in chronic insomnia, stress and sleep architecture research interest, no approved sleep indication. 3 sources indexed (1987–1999), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
DSIP biology remains incompletely resolved, with proposed effects on sleep architecture, stress-axis regulation, endogenous opioids, and mitochondrial or neuroendocrine signaling. Human sleep trials found mixed objective and subjective results, so the mechanism cannot be translated into reliable clinical benefit.3,1
Dosing & protocol.
Peptides are generally not reliably orally bioavailable unless a specific studied oral formulation is used. Human use of research-grade products is not appropriate.
What it actually costs.
Real-world pricing across three quality tiers. Assumes Research Injectable DSIP.
Research-market pricing is not a dosing recommendation; human use is not FDA-approved unless specifically stated. Updated 2026-06-04.
