Vanguard Laboratory COA verification coverage

Paste or upload the certificate. PeptidePrices uses the report ID to check the Vanguard Laboratory official lookup.Checking a report by hand? Our explainer on why a Vanguard report may not be in Verified by Vanguard shows how many Vanguard reports are not in the public index, why a missing record is shown as a neutral View COA rather than a failure, and what to check instead.

Verify by lab

Each lab has its own verification portal. Pick the lab named on the COA to see which code it uses.

A laboratory match applies to the exact certificate record. Physical-vial chain of custody remains separate.

Using COA evidence

Can I search COAs by vendor, compound, or lot?

Yes. The library indexes first-party public vendor archives and product-page report surfaces. Search a vendor name, compound, strength, batch, or lot, then open the exact public source. Results identify their count unit and evidence source so a gallery image, report panel, and certificate identity are not treated as the same thing.

How do I verify a peptide COA?

Paste the certificate's public link, upload the PDF or image, or copy an image and press Command-V or Control-V on this page. The checker identifies the issuing laboratory, looks the report identifier up in that lab's own public records, and reports whether the record matched, what purity the certificate claims, and which testing categories it covers.

Which laboratories can be checked?

The live laboratory directory shows whether each issuer has an automated public lookup, a verification-code workflow, or a finite indexed certificate corpus. Portal outages, challenges, private records, and lookup misses remain unresolved rather than being labeled fake.

How do I verify a Janoshik COA?

A Janoshik report prints a verification key and task number. Check both through Janoshik's official verification page, then match the client, compound, batch, analysis date, content, purity, and other returned fields to the vendor's certificate. A challenge, outage, or lookup failure remains unresolved rather than being labeled fake.

How do I check an ILS Laboratories COA?

Use the eight-character Access Code printed beneath the QR code or in the certificate footer. The checker displays that code prominently and keeps it copyable so you can reproduce the lookup in ILS's official verifier.

How do I check a Freedom Diagnostics COA?

Use the prefixed Search Code printed on the certificate, not the bare accession number. The checker displays that Search Code prominently and links the official Freedom record when it matches.

What does a matched record establish?

An issuer-native match supports the exact certificate record and its printed results. The tested sample, the vendor's copy, and physical-vial chain of custody remain separate evidence.

How can you identify an altered COA?

An exact identifier conflict is the strongest signal: the issuing source or another exact copy carries a different purity, batch, compound, or task. A lookup miss, outage, challenge, or unsupported provider remains unknown. Certificate-format differences are weaker document signals.

What should I match between a COA and a vial?

Match the compound name, labeled strength, batch or lot identifier, report date, and report number. Then confirm the report through the issuing laboratory's own verification portal where one exists.
