DSIP
DSIP
A nonapeptide, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, first isolated from rabbit cerebral venous blood. Neither a gene encoding it nor a receptor for it has been established in the published literature, which is unusual for a peptide described more than fifty years ago.
No registered human study names DSIP as an intervention. ClinicalTrials.gov holds no trial of it, so there is no trial evidence to read — a fact about the public record rather than proof the compound does nothing. No FDA-approved product contains DSIP. 11 papers naming it were published in the last ten years.
Collected 2026-08-02 from ClinicalTrials.gov and Drugs@FDA. Counts include only trials whose registered intervention names DSIP; the registry search is fuzzy, so every match is re-checked. None of this says whether DSIP works or is safe.

No FDA-approved product contains it
No study of DSIP in humans is registered on ClinicalTrials.gov. That is a fact about the public record, not a statement that the compound does nothing — but it does mean there is no trial evidence to read, and anyone telling you otherwise should be asked for the registration number. The grade is mechanical: it is computed from the registry and the FDA record alone, and it grades how much is known, never whether a compound is good or safe. Collected 2026-08-02 from ClinicalTrials.gov and Drugs@FDA. Check the query.
What DSIP is, and what it has been studied for
DSIP is classified by ChEMBL as a protein.
No registered trial names DSIP as an intervention, so there is no condition it has been formally studied in. It does have a literature: 11 indexed papers name it in the last ten years. That work is laboratory and animal research, and a paper is not a trial.
Is anyone studying DSIP?
Papers published each year that name DSIP in the title or abstract, with the clinical trials that started in the same year marked beneath. Ten calendar years.

11 papers between 2017 and 2026. A paper counts when “DSIP” appears in its title or abstract — phrase-matched, so a paper mentioning the words separately is not counted. The total is a single query over the whole window, which is why it does not equal the bars added together: PubMed files a paper under both its electronic and its print publication date, so one paper can appear in two years. Publication volume measures scientific attention, not whether a compound works: a well-studied compound can be well-studied and ineffective.

Reading on this compound
All articles →PepRack articles that reference this compound. This is not a news feed — we syndicate nothing and publish no datelines.
Vendor listings are not affiliate links and PepRack earns nothing from them. A listing records a price we observed on a date. It is not a recommendation of a product, dose, or treatment, and PepRack does not verify what any vendor ships.
