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.
Terlipressin
Terlipressin is slowly converted in the body to lysine-vasopressin by cleavage of the three N-terminal glycyl residues (reservoir effect) and activates V1 receptors. The splanchnic vasoconstriction improves renal perfusion in hepatorenal syndrome.

Frequently asked questions
- What is the difference between DSIP and Terlipressin?
- DSIP is classified as "Onderzoek (overig)", while Terlipressin 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. Terlipressin: Terlipressin is a 12-amino-acid vasopressin analog and prodrug of lysine-vasopressin. As a V1 receptor agonist it is vasoconstrictive and is approved for hepatorenal syndrome (FDA 2022, Terlivaz). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, DSIP or Terlipressin?
- The highest available evidence level is "Humane studie" for DSIP and "Humane RCT" for Terlipressin. 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 Terlipressin in Germany and the United States?
- Duitsland: DSIP — Niet goedgekeurd, Terlipressin — Op recept. Verenigde Staten: DSIP — Niet goedgekeurd, Terlipressin — Op recept. These are factual summaries with source and review date on the individual pages.
