Werkingsmechanisme
DSIP
DSIP was described in 1977 by the Schoenenberger-Monnier group in Basel as a blood-borne substance reported to induce EEG changes similar to delta sleep in animal models. The exact mechanism remains undefined to this day: no defined receptor, proposed modulation of opioid, GABAergic and glutamatergic systems. Most mechanistic findings stem from preclinical studies of the 1980s and 1990s and were later subjected to contested replication attempts.
Plecanatid
Plecanatide is structurally analogous to the body's own uroguanylin and, like it, activates the GC-C receptor at the gut surface, raising cGMP and fluid secretion. Its pH-dependent activity shifts the effect toward the proximal small intestine.

Frequently asked questions
- What is the difference between DSIP and Plecanatid?
- DSIP is classified as "Onderzoek (overig)", while Plecanatid is classified as "Onderzoek (overig)". DSIP: Synthetic nonapeptide isolated in 1977 by Guido Monnier and Marcel Schoenenberger from the blood of rabbits in delta sleep. Despite the name, the role in sleep regulation is contested and not confirmed by Western RCTs in larger populations. Plecanatid: Plecanatide is a 16-amino-acid analog of the body's own uroguanylin and a guanylate cyclase-C (GC-C) agonist. It is approved for chronic idiopathic constipation (CIC) and IBS with constipation (IBS-C). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, DSIP or Plecanatid?
- The highest available evidence level is "Humane studie" for DSIP and "Humane RCT" for Plecanatid. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of DSIP and Plecanatid in Germany and the United States?
- Duitsland: DSIP — Niet goedgekeurd, Plecanatid — Niet goedgekeurd. Verenigde Staten: DSIP — Niet goedgekeurd, Plecanatid — Op recept. These are factual summaries with source and review date on the individual pages.
