Overview
Khavinson bioregulator tetrapeptide (KEDG) originally isolated from testicular tissue extracts. Developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, it promotes testosterone biosynthesis by stimulating Leydig cell activity and improving cellular metabolism in testicular tissue. Works through epigenetic regulation, crossing cell and nuclear membranes to interact directly with DNA of target tissues.
