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.
Semax
Semax is a tetracosactide fragment analog without hormonal activity at MC2R. Proposed mechanisms include elevation of BDNF and NGF in hippocampus and striatum (in animal models), modulation of dopamine metabolism, and neuroprotective effects via anti-apoptotic pathways. A clear primary receptor is not established.

Frequently asked questions
- What is the difference between DSIP and Semax?
- DSIP is classified as "Ricerca (altro)", while Semax 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. Semax: Synthetic heptapeptide derived from the N-terminal fragment of adrenocorticotropic hormone (ACTH 4-10). Approved in Russia for ischaemic stroke, cognitive function and ADHD in children. Western phase-3 trials absent. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, DSIP or Semax?
- The highest available evidence level is "Studio sull'uomo" for DSIP and "Studio sull'uomo" for Semax. 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 Semax in Germany and the United States?
- Germania: DSIP — Non approvato, Semax — Non approvato. Stati Uniti: DSIP — Non approvato, Semax — Non approvato. These are factual summaries with source and review date on the individual pages.
