Mechanism of action
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.
Glepaglutide
As a GLP-2 receptor agonist, glepaglutide has a trophic effect on the intestinal mucosa, enlarging the absorptive surface and thereby improving intestinal uptake of nutrients and fluid.

Frequently asked questions
- What is the difference between Epitalon and Glepaglutide?
- Epitalon is classified as "Research other", while Glepaglutide is classified as "Research other". 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. Glepaglutide: Glepaglutide is a long-acting GLP-2 analogue (Zealand Pharma) intended to reduce the need for parenteral support in short bowel syndrome. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Epitalon or Glepaglutide?
- The highest available evidence level is "Human trial" for Epitalon and "Human RCT" for Glepaglutide. 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 Glepaglutide in Germany and the United States?
- Germany: Epitalon — Unapproved, Glepaglutide — Unapproved. United States: Epitalon — Unapproved, Glepaglutide — Unapproved. These are factual summaries with source and review date on the individual pages.
