What is Livagen?
Livagen is a synthetic tetrapeptide with the sequence Lys-Glu-Asp-Ala (KEDA). It is one of the short “peptide bioregulators” studied by Vladimir Khavinson’s group at the St. Petersburg Institute of Bioregulation and Gerontology. In that group’s published work it is associated with the liver.
