What Is Testagen?

Testagen is a synthetic tetrapeptide composed of lysine, glutamic acid, aspartic acid, and glycine (KEDG). It belongs to the family of short peptide bioregulators developed by Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology, a class of ultrashort peptides studied as organ-specific regulatory molecules.

In laboratory settings, Testagen is investigated for proposed peptide-DNA and peptide-histone interactions that may modulate gene expression, a mechanism described across the Khavinson peptide family. Its short, defined sequence makes it a straightforward tool for studying how ultrashort peptides interact with chromatin in controlled models.

Present understanding derives from in vitro assays and animal models, much of it published in the Russian-language literature. Findings should be interpreted within their experimental context and not treated as established outcomes for any use supplied by Puritide Research. Testagen is supplied strictly for laboratory use and is not approved for human or veterinary application.
