Overview of Epitalon-Highly Bioactive Pineal Tetrapeptide with Promising Properties.
International journal of molecular sciences|2025|Araj S et al.
Epitalon, also known as Epithalon or Epithalone, is a tetrapeptide, Ala-Glu-Asp-Gly (AEDG), which was synthesized based on the amino acids composition of Epithalamin, a bovine pineal gland extract, prior to its discovery in pineal gland polypeptide c…

Epitalon increases telomere length in human cell lines through telomerase upregulation or ALT activity.
Biogerontology|2025|Al-Dulaimi S et al.
Epitalon, a naturally occurring tetrapeptide, is known for its anti-aging effects on mammalian cells. This happens through the induction of telomerase enzyme activity, resulting in the extension of telomere length. A strong link exists between telome…
