Overview
Testagen is a synthetic Khavinson tetrapeptide (Lys-Glu-Asp-Gly, KEDG) marketed as a testicular bioregulator for male reproductive and hormonal support. It is proposed to enter the cell nucleus, bind short DNA sequences, and tune gene expression in testicular tissue, supporting steroidogenesis (testosterone production by Leydig cells) and spermatogenesis. Evidence is limited to one small Russian clinical report and theoretical framework, with no independent replication or Western randomized controlled trials.
