Meccanismo d'azione
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.
Nafarelin
Nafarelin is a potent GnRH agonist: after an initial stimulation ('flare'), continuous receptor occupancy leads to downregulation and thereby suppression of LH, FSH and the downstream sex hormones.

Frequently asked questions
- What is the difference between DSIP and Nafarelin?
- DSIP is classified as "Ricerca (altro)", while Nafarelin is classified as "Ricerca (altro)". 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. Nafarelin: Nafarelin is a GnRH agonist and the only member of this class delivered as a nasal spray. It is approved for treating endometriosis and central precocious puberty. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, DSIP or Nafarelin?
- The highest available evidence level is "Studio sull'uomo" for DSIP and "RCT sull'uomo" for Nafarelin. 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 Nafarelin in Germany and the United States?
- Germania: DSIP — Non approvato, Nafarelin — Su prescrizione. Stati Uniti: DSIP — Non approvato, Nafarelin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
