Verify a peptide COA.
Paste a Kovera code, a Janoshik test ID or link, or a batch number. We check it against the labs' public records we have mirrored, and tell you when we retrieved them.

What the result tells you
MATCH · MISMATCH · NOT FOUND- Matches the lab's record.The certificate is in the lab's public records as of the retrieval date shown, and any purity you entered agrees with it.
- Certificate found, purity differs.The certificate exists, but the figure you were shown is not the lab's figure. Check your typing, then compare against the lab's page.
- Not in our mirror. Our snapshot does not hold that code. It may be newer than the snapshot or never made public. Check the lab directly before drawing any conclusion.
What this tool does not do
- It does not query the labs live.It reads our dated copy. The lab's own page is the source of truth, and each result links to it.
- It does not verify the vial in your hand. A certificate covers one lot. Confirm the lot on your vial matches the lot on the record. This is step 4 of our four-step verify method.
- It does not catch a reused certificate. A vendor can attach one clean certificate to several shipments. Only testing a different lot answers that. See our analysis of 1,828 Kovera COAs for how often lots repeat.
Questions
5 ANSWERSHow do I verify a Kovera Labs COA?
Paste the certificate code, which starts with KVR- (for example KVR-2026-EB005D), or the full koveralabs.com verify link into the box above. If the code is among the 1,828 Kovera certificates we mirror, you see the client, product, lot, purity, quantity, test date and pass or fail as Kovera published them, plus the date we retrieved it. Then open Kovera's own verify page for the current version. Is Kovera Labs legit? How to verify.
How do I verify a Janoshik COA?
Paste the Janoshik test number or the janoshik.com verification link the vendor gave you. A match shows the lab-identified compound, purity, quantity, batch and test date from Janoshik's public record. Then confirm the batch printed on your vial matches the batch on the record. Janoshik verify: the four-step method.
What does a mismatch mean?
The certificate exists, but the purity you entered differs from the lab's record. First check you copied the figure correctly. If it still differs, the document you were shown is not the one the lab published, which is how an edited certificate looks. Ask the vendor for the lab's own verification link and compare.
What if my certificate is not in your mirror?
Our mirror is a dated snapshot of each lab's public records, so a certificate issued after that date will not be in it, and some tests are never made public. A miss here is not evidence of a fake. Check the code on the lab's own site.
Why can a COA change after it is published?
Some labs re-issue a certificate under the same number when they correct or re-certify it. Kovera has done this, so the document behind a Kovera code is the current version rather than a permanent one. Note the date you checked a certificate. How Kovera revised COAs in place.
