Werkingsmechanisme
Epitalon
Postulated mechanisms include modulation of gene expression in pinealocytes, telomerase activation (observed in cell culture studies) and influence on melatonin synthesis. A defined primary receptor is not established; the mechanistic basis rests on in-vitro and animal data from the Khavinson group.
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 Epitalon and Nafarelin?
- Epitalon is classified as "Onderzoek (overig)", while Nafarelin is classified as "Onderzoek (overig)". Epitalon: Synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the pineal extract epithalamin (V. Khavinson, St. Petersburg). Investigated in the Russian research and anti-ageing context; Western controlled trials are largely absent. No medicines approval in EU or US. 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, Epitalon or Nafarelin?
- The highest available evidence level is "Humane studie" for Epitalon and "Humane RCT" 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 Epitalon and Nafarelin in Germany and the United States?
- Duitsland: Epitalon — Niet goedgekeurd, Nafarelin — Op recept. Verenigde Staten: Epitalon — Niet goedgekeurd, Nafarelin — Op recept. These are factual summaries with source and review date on the individual pages.
