A peptide name linked to sleep does not establish that a marketed product improves insomnia or sleep quality.

01 / CLASSIFICATION

What is DSIP?

Entity typeNative peptide
Research categoryCognition
Known namesDSIP, Delta sleep-inducing peptide
Editorial unitOne molecule or defined product record

Names, fragments, salts, formulations, routes, and branded products are kept distinct whenever transferring evidence would change the conclusion.

02 / EVIDENCE

DSIP human and preclinical evidence.

HUMAN
1/5 · Very small historical studies

Human sleep studies were tiny and conducted decades ago; they do not establish a modern therapeutic evidence base.

PRECLINICAL
2/5 · Uncertain physiology

Historical laboratory research explored sleep and stress physiology, with unresolved questions about identity and mechanism.

The five-point bars describe the maturity and depth of the evidence base. They do not score effectiveness, safety, or personal suitability.

03 / STATUS

DSIP FDA and sport status.

U.S. FDANo FDA-approved DSIP drug product; FDA enforcement records have described DSIP products as unapproved new drugs.
2026 WADANot specifically named in the 2026 WADA List; athletes should verify current status and product contents.
Commercial accessPeptideAgent does not route unapproved research substances to sellers.
