Meccanismo d'azione

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 "Ricerca (altro)", while Nafarelin is classified as "Ricerca (altro)". 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 "Studio sull'uomo" for Epitalon 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 Epitalon and Nafarelin in Germany and the United States?: Germania: Epitalon — Non approvato, Nafarelin — Su prescrizione. Stati Uniti: Epitalon — Non approvato, Nafarelin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
