Description

Overview

Epitalon, also spelled Epithalon, is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It was developed from research on pineal peptide preparations and has been investigated in cellular-aging, telomere, circadian, antioxidant, and gene-expression models. Some laboratory studies report changes in telomerase activity and telomere-related endpoints, while human literature is largely composed of older studies from a limited number of research groups. Claims about lifespan extension or reversal of human aging are not supported by the evidence.

How It Works

Telomere biology: Cell-culture research has examined telomerase activity and replicative-senescence endpoints.
Gene regulation: Peptide-gene interactions and transcriptional effects have been investigated in experimental systems.
Circadian biology: Research has explored pineal signaling, melatonin rhythms, and age-related circadian changes.

Cellular aging
Telomere and telomerase research
Circadian signaling
Oxidative-stress models

Research / Study Context

Cell-culture studies: Human somatic-cell models have been used to examine telomerase and replicative lifespan.
Aging research: Older animal and human studies explored circadian, immune, and gerontological endpoints.

Key Research Findings

Laboratory evidence supports continued investigation of telomere-related mechanisms.
Human evidence is limited and not sufficient to establish anti-aging efficacy.
The literature distinguishes between cell, animal, and human findings.
