Research Information

DSIP/emideltide is a defined nine-amino-acid peptide that has been investigated in scientific research involving peptide biology and neurobiological systems.

The compound is represented in FDA’s Substance Registration System under the preferred substance name EMIDELTIDE, with DSIP and Delta Sleep-Inducing Peptide listed as synonyms. FDA’s registry also makes clear that a substance’s UNII listing does not mean that the substance has undergone FDA regulatory review or approval.

FDA’s 2026 Pharmacy Compounding Advisory Committee materials evaluated emideltide (free base) and emideltide acetate as separate bulk drug substances. FDA states that neither is a component of an FDA-approved drug.

FDA has also identified potential concerns for compounded products containing emideltide, including possible immunogenicity for certain routes of administration and complexities involving peptide-related impurities and API characterization.

Accordingly, this listing is intentionally limited to compound identity, chemical characteristics, and research classification. It does not represent DSIP as a sleep treatment, medication, or therapeutic product.

Research Applications

DSIP may be examined as a research material in controlled laboratory environments for purposes such as:

Peptide characterization
Analytical testing
Structural investigation
Molecular research
Comparative peptide studies
Laboratory assay development
Neurobiological research
Peptide-related experimental research

These statements describe potential research contexts only and do not constitute recommendations for administration to humans or animals.

Important Product Information

Chemical form must be verified before publishing the product specifications.

FDA distinguishes emideltide free base from emideltide acetate as separate bulk drug substances. PubChem likewise identifies DSIP acetate separately, with a molecular weight of approximately 908.9 g/mol.

Therefore, the specifications above should only be used when your actual material corresponds to DSIP/emideltide free base. If your supplier’s COA identifies the product as DSIP acetate, the product page should use the acetate-specific chemical information instead.

Product identity, peptide sequence, purity, salt form, analytical results, and other batch-specific specifications should be verified against the applicable Certificate of Analysis (COA).
