Epithalon
Epithalon, also called Epitalon or AEDG, is a synthetic linear tetrapeptide composed of Ala-Glu-Asp-Gly and derived from the pineal extract epithalamin. It is not FDA-approved. FDA lists it among substances nominated for compounding whose nomination was withdrawn, and no EMA, UK MHRA or Australian ARTG marketing authorization was identified in the reviewed evidence. [3][4]
