THE LIVER REVITALIZER

Lys-Glu-Asp-Ala

Livagen is a synthetic tetrapeptide bioregulator that can actually interact with your DNA to influence gene expression. It's been shown to activate genes in immune cells that may have become "silenced" with age. It may help restore youthful immune function and cellular repair capacity.
