Livagen — 20mg | KEDA Khavinson Liver Peptide

Livagen is a synthetic tetrapeptide bioregulator consisting of the sequence Lys-Glu-Asp-Ala (KEDA), developed by the Khavinson group at the St. Petersburg Institute of Bioregulation and Gerontology in Russia. The compound name traces to “liver” in the Khavinson nomenclature — Livagen is the tetrapeptide identified by Khavinson and colleagues as the liver tissue-derived peptide bioregulator within the broader cytomedin / cytogen peptide family. Some Russian academic literature additionally reports zinc-coordinating activity for Livagen, with research focus on peptide-metal interactions in chromatin structure and gene expression contexts. The compound has been investigated in the Russian academic literature (Bulletin of Experimental Biology and Medicine; Khavinson, Anisimov, and colleagues) for hepatic cell gene expression, chromatin biology, and age-associated cellular research endpoints in preclinical research models. Like other Khavinson short-peptide bioregulators, Livagen is studied primarily as a research tool for tissue-specific peptide pharmacology rather than as a defined receptor agonist.
