EDL Tripeptide · Liver & GI Bioregulator
Tripeptide bioregulator (EDL) of the Khavinson series, acting mainly on the gastrointestinal tract and the liver. Dr. Vladimir Khavinson developed it at the St. Petersburg Institute of Bioregulation and Gerontology. Long-term liver fibrosis is reduced, and the GI mucosal layer is shielded against chemotherapy, environmental toxins, and antibiotics. Like the other bioregulators it passes through cell and nuclear membranes, regulating DNA transcription patterns directly, with effects specific to tissue.
Overview
Tripeptide bioregulator (EDL) of the Khavinson series, acting mainly on the gastrointestinal tract and the liver. Dr. Vladimir Khavinson developed it at the St. Petersburg Institute of Bioregulation and Gerontology. Long-term liver fibrosis is reduced, and the GI mucosal layer is shielded against chemotherapy, environmental toxins, and antibiotics. Like the other bioregulators it passes through cell and nuclear membranes, regulating DNA transcription patterns directly, with effects specific to tissue.
Epigenetic regulation is the mechanism: Ovagen crosses cell and nuclear membranes to act directly on DNA structure and transcription patterns. Entry into the cell runs through POT family transporters (PEPT1, PEPT2), which handle di- and tripeptides specifically — hence the precision of its tissue targeting. Effects are tissue-specific to liver and GI tract, with fibrosis reduced and mucosal integrity protected.
Research indications

FAQ
How does Ovagen protect the gut from antibiotic damage?
Ovagen (the EDL tripeptide) protects the GI mucosal layer against antibiotic-induced damage. Transport by PEPT1/PEPT2 carries the peptide directly to gut tissue, where gene expression is regulated to strengthen mucosal integrity. Taken during and after a course of antibiotics, it may help preserve the microbiome.
Does Ovagen combine with other Khavinson bioregulators?
Yes. Synergy holds with Livagen, Epitalon and other Khavinson peptides, which target different tissues. Multiple bioregulators run together in many anti-aging protocols — Ovagen for liver and GI, Epitalon for telomeres, and so on. Recommended cycling protocols are followed to avoid overstimulation.
Over what period does Ovagen reduce liver fibrosis?
Results are cumulative. Gene expression changes start immediately within a 10–20 day cycle, while visible improvement in liver fibrosis arrives over weeks to months across periodic cycles. Maintenance runs 2–3 cycles yearly, which implies ongoing use for fibrosis reduction over the long term.
Capsule or injection — which form of Ovagen is better?
Both routes work. Oral capsules are the more convenient for daily dosing and store at room temperature. Injectable forms absorb directly but need refrigeration and reconstitution. The choice runs between convenience (capsules) and guaranteed absorption (injection).
