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.
Bremelanotide
Bremelanotide is a cyclic peptide that binds non-selectively to melanocortin receptors (MC1R through MC5R) — with highest affinity at MC4R in the central nervous system. The precise role of MC4R activation in sexual behaviour is not fully understood; animal data show effects on hypothalamic circuits. Peripheral effects (blood pressure, hyperpigmentation) are attributed to MC1R/MC2R.

Frequently asked questions
- What is the difference between Epitalon and Bremelanotide?
- Epitalon is classified as "Ricerca (altro)", while Bremelanotide 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. Bremelanotide: Synthetic cyclic heptapeptide acting as a non-selective melanocortin-receptor agonist. FDA-approved in 2019 as Vyleesi for hypoactive sexual desire disorder (HSDD) in pre-menopausal women. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Epitalon or Bremelanotide?
- The highest available evidence level is "Studio sull'uomo" for Epitalon and "RCT sull'uomo" for Bremelanotide. 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 Bremelanotide in Germany and the United States?
- Germania: Epitalon — Non approvato, Bremelanotide — Non approvato. Stati Uniti: Epitalon — Non approvato, Bremelanotide — Su prescrizione. These are factual summaries with source and review date on the individual pages.
