Which vendors sell Epithalon with independent COA testing?

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

To verify Epithalon 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 Epithalon at https://meritverified.org/peptides/epitalon so you can compare evidence across vendors before buying.

What is the regulatory status of Epithalon?

Epithalon is tracked in the Merit Verified registry. Regulatory status for research peptides in the US has been evolving — the FDA has reclassified a number of peptides out of the 503A compounding ingredient list since 2025. Merit Verified does not provide legal or regulatory advice; check official FDA sources or consult a licensed professional for the current status of Epithalon in your jurisdiction.

Immune Modulator

Epithalon

Also known as: Epitalon (AEDG, synthetic analog of Epithalamin)

Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by Khavinson as an analog of the bovine pineal extract Epithalamin. It is a research-only bioregulator — not FDA-approved — investigated for claimed telomerase activation and circadian/melatonin effects, with evidence limited primarily to Khavinson-group studies.
