Epitalon
Lyophilized in the USA390.35 g/molTetrapeptide
Epitalon is a short peptide of four amino acids: Ala-Glu-Asp-Gly, or AEDG. It is also spelled epithalon or epithalone. It was designed in St Petersburg from the amino acid makeup of epithalamin. Epithalamin is an extract of cattle pineal glands, so the two are not the same thing.
