Epithalon

Epithalon, also published as Epitalon and AEDG peptide, is catalogued here as: Synthetic tetrapeptide (Ala-Glu-Asp-Gly). Studied in human fibroblast cultures for telomerase activity and telomere length, not human longevity. A four-part peptide studied in lab-grown human cells for telomeres, the protective ends of chromosomes, and the enzyme that maintains them.

Cells literature: The 2003 paper reported induced telomerase activity in telomerase-negative human fetal fibroblast cultures. Human cells in culture are not human participants.

Cells literature: Telomere elongation was reported in the same cultured-cell experiment. This does not establish longer life, anti-ageing efficacy or safety in people.

When comparing published work, match the exact molecular identity, salt form and strength to the paper. Findings in cell or animal models describe those models only and do not establish outcomes in people.
