Lab Testing

Every lot, independently tested.

Each lot we stock is tested by Vanguard Laboratory, an independent third-party lab, for identity and purity before it ships. Results are tied to that specific lot, not to a product line as a whole.

What members see

On each product page, signed-in members can see the current lot number, its laboratory ID, the test date, and a link to that lot's certificate of analysis (COA).

How to verify a COA

1. Find the lot number on your vial label. It looks like 2406-SLOS-001.
2. Sign in or create a free member account, then enter the lot number in the lookup above. You'll see the laboratory ID, the test date and a link to the certificate.
3. Open the certificate from the lookup, or scan the QR code on your vial. Either way it should open on Vanguard's website (verifiedbyvanguard.com), not ours.
4. Check that the laboratory ID on the certificate matches the one shown in the lookup.
5. Review the test date and the reported identity and purity results.
