Epithalon

Ala-Glu-Asp-Gly Synthetic Pineal Tetrapeptide (AEDG / Epitalon)

Epithalon is a synthetic biomimetic tetrapeptide modeled after the endogenous pineal peptide epithalamin. Investigated for its ability to induce telomerase reverse transcriptase (TERT) expression, elongate telomeres in human somatic cells, modulate melatonin synthesis, and reduce oxidative mitochondrial stress.
