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.
Octreotide
Octreotide is a cyclic octapeptide that selectively binds somatostatin-receptor subtypes SSTR2 and SSTR5. Via G-protein-coupled signalling, adenylyl cyclase is inhibited, reducing the secretion of multiple hormones (growth hormone, IGF-1, glucagon, insulin, VIP, serotonin). Structural stabilisation via a disulfide bridge and D-amino acids extends the half-life relative to natural somatostatin (minutes to several hours).

Frequently asked questions
- What is the difference between Epitalon and Octreotide?
- Epitalon is classified as "Исследования (прочее)", while Octreotide is classified as "Исследования (прочее)". 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. Octreotide: Synthetic octapeptide somatostatin analog with a longer half-life than endogenous somatostatin. FDA- and EMA-approved since the 1980s for acromegaly and neuroendocrine tumours. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Epitalon or Octreotide?
- The highest available evidence level is "Исследование на людях" for Epitalon and "РКИ на людях" for Octreotide. 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 Octreotide in Germany and the United States?
- Германия: Epitalon — Не одобрено, Octreotide — Рецептурный. США: Epitalon — Не одобрено, Octreotide — Рецептурный. These are factual summaries with source and review date on the individual pages.
