Epitalon (Epithalon) Peptide 5mg (≥99% Purity) – Research Grade Tetrapeptide
Product Overview
Epitalon (also known as Epithalon or Epithalone) is a synthetic tetrapeptide with the amino acid sequence Ala-Glu-Asp-Gly (AEDG) . It was developed based on the amino acid composition of Epithalamin, a bioactive polypeptide extract derived from the bovine pineal gland, and was later confirmed to naturally occur in the pineal gland .
Over the past 25 years, Epitalon has been extensively studied using in vitro, in vivo, and in silico methods. Research indicates significant geroprotective and neuroendocrine effects, including antioxidant, neuroprotective, and antimutagenic activities . As of 2025, a 2025 review summarizing the current state of knowledge on Epitalon has been published . The peptide remains under pre-clinical and clinical development and has not been approved for any therapeutic use by the FDA or European health authorities .
Mechanism of Action
Epitalon exerts its biological effects through multiple pathways:
-
Telomerase Activation: Upregulates telomerase activity, promoting telomere elongation in human somatic cells . Recent research (2025) suggests Epitalon can increase telomere length in human cell lines .
-
Pineal Gland & Melatonin Regulation: Directly influences melatonin synthesis in pinealocytes, potentially via modulation of the pCREB transcription factor and AANAT enzyme .
-
Immune Modulation: Alters interleukin-2 (IL-2) mRNA levels and modulates the mitogenic activity of murine thymocytes .
-
Enzyme Modulation: Enhances activity of various enzymes including acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), and telomerase .
-
Chromatin Activation: Induces activation of ribosomal genes and decondensation of heterochromatin, potentially reversing age-related gene repression .
Key Research Applications:
-
Telomerase activation and telomere length studies
-
Aging and geroprotection research
-
Neuroprotection and cognitive function studies
-
Circadian rhythm and pineal gland research
-
Cancer and tumor suppression research (spontaneous tumor models)
