Short answer
Epitalon (also written Epithalon) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It has been studied since the 1990s in telomere biology, pineal gland research and longevity-related models. It is sold as a lyophilized research powder for laboratory use only.
Structure and origin
Epitalon is one of the shortest research peptides on the market - just four amino acids: alanine, glutamic acid, aspartic acid and glycine. It was designed by the Russian researcher V. Khavinson and colleagues, who studied short peptides derived from tissue extracts and their effects on cellular aging models.
A 2003 study in the Bulletin of Experimental Biology and Medicine reported that Epithalon induced telomerase activity and telomere elongation in human somatic cell cultures [1]. Telomeres are the protective caps at the ends of chromosomes, and telomerase is the enzyme that maintains them - which is why Epitalon appears in longevity research.
