Epithalon (also known as Epitalon or Epithalone or AEDG) is a therapeutically researched peptide studied for its effects on anti-aging, sleep, injectable. Synthetic pineal tetrapeptide (Ala-Glu-Asp-Gly) studied as a geroprotector — antioxidant, telomerase-enhancing, and melatonin-modulating effects. Preclinical evidence only; no controlled human trials. Not FDA-approved.

Epithalon (also spelled Epitalon or Epithalone) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly (AEDG), synthesized to reproduce the active amino acid composition of Epithalamin, a peptide extract of the bovine pineal gland. Over more than two decades of in vitro, in vivo, and in silico research it has been characterized as a geroprotective and neuroendocrine compound, with antioxidant, neuroprotective, and antimutagenic activity attributed to both specific and nonspecific mechanisms. Reported effects include direct influence on melatonin synthesis, modulation of interleukin-2 mRNA levels and thymocyte mitogenic activity, and enhancement of several enzymes including telomerase, which underlies its frequently cited anti-aging and telomere-maintenance claims.

Natty status
Epithalon is generally regarded as compatible with natural bodybuilding, though competitive federations may differ. See § Natty status.

Overview

Despite the volume of preclinical work, controlled human clinical trials are lacking, and its precise mechanisms remain incompletely defined.

Epithalon is not FDA-approved for therapeutic use and remains an investigational, unregulated research compound.

Mechanism of action

Marketed as an anti-aging peptide. In preclinical studies it boosts telomerase activity, supports the body's own melatonin production, and shows antioxidant effects. Human evidence is minimal.

Reported effects

Effects reported in the literature and from preclinical models include:

  • Epithalon demonstrates geroprotective and neuroendocrine effects through antioxidant, neuroprotective, and antimutagenic mechanisms in preclinical in vitro and in vivo studies. [2] Preclinical
  • Epithalon enhances the activity of several enzymes including telomerase, supporting telomere maintenance as a potential anti-aging mechanism. [2] Preclinical
  • Epithalon directly influences melatonin synthesis in the pineal gland, modulating neuroendocrine function. [2] Preclinical
  • Epithalon modulates immune function by altering interleukin-2 mRNA levels and the mitogenic activity of murine thymocytes. [2] Preclinical
  • Epithalon targets circadian and mitochondrial regulatory pathways relevant to recovery, with no clinical trial evidence currently available. [1][2] Preclinical

Evidence grades: FDA approved Phase III Phase II Phase I Preclinical Anecdotal

Dosage and administration

⚠

Subcutaneous

  • Common research protocol: 5-10mg per day for 10-20 consecutive days, run as a course 1-2 times per year
  • Lower-dose course: 1-3mg per day over a 10-day cycle

Cycle

  • short 10-20 day courses rather than continuous daily use

Note

  • no validated clinical dosing exists; figures reflect commonly published research protocols, not approved guidance

Natty status

See also: Peptide § Natty status

Epithalon is generally regarded as compatible with the natty designation, particularly when used for therapeutic healing purposes. Opinions vary across natural bodybuilding federations, and athletes who compete should consult the rulebook of their respective sanctioning body.[3]
