Question 1

What is Ovagen?

Accepted Answer

Ovagen is a synthetic tripeptide (Glu-Asp-Leu, EDL) short-peptide bioregulator developed by Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology, marketed as a liver/gastrointestinal bioregulator. The Khavinson group reports it modulates gene expression in hepatocytes and GI mucosal epithelium via direct peptide-DNA interaction, with proposed effects on protein synthesis and hepatocellular repair. Evidence is limited to single-group preclinical and small clinical work; it is not FDA-approved and lacks independent Western validation. Reported CAS numbers conflict across sources, so no CAS Registry Number is asserted here. Merit Verified tracks independent COA test results for Ovagen from multiple vendors.

Question 2

Which vendors sell Ovagen with independent COA testing?

Accepted Answer

2 vendors in the Merit Verified directory have independent COA evidence on file for Ovagen — 5 COAs total. COA coverage and test dates are listed on the Ovagen page at https://meritverified.org/peptides/ovagen.

Question 3

How do I verify the quality of Ovagen from a vendor?

Accepted Answer

To verify Ovagen quality, look for an independent certificate of analysis (COA) from a third-party lab — not a lab the vendor owns or pays directly. The COA should state the tested compound, lot number, purity percentage (identity and concentration), and the lab's name. Cross-reference the lot number against the vendor's current stock. Merit Verified indexes COAs for Ovagen at https://meritverified.org/peptides/ovagen so you can compare evidence across vendors before buying.

Question 4

What is the regulatory status of Ovagen?

Accepted Answer

Ovagen is classified as research-use only in the Merit Verified registry. In the United States, the FDA removed several peptides including BPC-157, TB-500, and GLP-1 analogues from the 503A compounding ingredient list in April 2026, restricting their use in compounded drugs for human administration. Vendors selling Ovagen for research purposes are not selling it as a drug or supplement; the legal status of purchasing for personal use varies by jurisdiction. Merit Verified does not provide legal or medical advice — confirm current regulatory status with a licensed professional.
