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.
Triptorelin
Triptorelin binds with high affinity to the GnRH receptor in the pituitary. After initial stimulation of LH and FSH secretion (flare phase, about 1-2 weeks), receptor desensitisation follows with consecutive gonadotropin suppression. This results in a reversible chemical castration: in men testosterone, in women oestrogen suppression to the postmenopausal range.

Frequently asked questions
- What is the difference between DSIP and Triptorelin?
- DSIP is classified as "Ricerca (altro)", while Triptorelin 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. Triptorelin: Synthetic decapeptide GnRH agonist with increased affinity over native gonadotropin-releasing hormone. FDA- and EMA-approved since the 1980s for prostate cancer, endometriosis and 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 Triptorelin?
- The highest available evidence level is "Studio sull'uomo" for DSIP and "RCT sull'uomo" for Triptorelin. 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 Triptorelin in Germany and the United States?
- Germania: DSIP — Non approvato, Triptorelin — Su prescrizione. Stati Uniti: DSIP — Non approvato, Triptorelin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
