What is Epithalon?
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly (AEDG). Developed by Russian scientist Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, Epithalon is based on epithalamin—a peptide extract from the pineal gland.
Epithalon has been studied primarily for its potential effects on telomerase activity, the enzyme responsible for maintaining telomere length. As telomere shortening is associated with cellular aging, Epithalon has become a focus of longevity and anti-aging research.

Frequently Asked Questions
What is the relationship between Epithalon and telomerase?
Epithalon is studied for its potential to activate telomerase, specifically by increasing expression of hTERT (the catalytic subunit). Research suggests this may allow cells to maintain or extend telomere length, potentially extending cellular replicative capacity.
Is Epithalon the same as epithalamin?
Epithalon is a synthetic tetrapeptide (AEDG) based on the active component identified in epithalamin, which is a peptide extract from pineal glands. Epithalon is the purified, synthesized version with a defined sequence.
How is Epithalon typically administered in research?
Subcutaneous injection is most common in research settings. Studies often use cycling protocols (e.g., 10-20 day cycles with rest periods). Dosing varies by study design and model organism.
Does Epithalon affect melatonin?
Research suggests possible effects on pineal function and melatonin production, given Epithalon's origin from pineal extracts. Some studies report improved circadian function and melatonin levels, though mechanisms are still being studied.
Could telomerase activation cause cancer?
This is a theoretical concern since cancer cells often have active telomerase. However, research has not shown carcinogenic effects with Epithalon. The distinction may be that Epithalon supports normal telomerase function rather than abnormal activation. Long-term studies continue.
How long do Epithalon cycles typically last?
Research protocols commonly use 10-20 day cycles with rest periods between. Some studies use longer continuous protocols. Cycling approaches may relate to receptor sensitivity and physiological response patterns.
