What every certificate covers
Find your lot
Enter the lot number printed on your vial, or the compound name. Every figure below is read from the certificate itself — open the document to see the chromatogram and mass confirmation.
Certificates are issued by Freedom Diagnostics and carry a search code that resolves on the laboratory's own site at FreedomDiagnosticsTesting.com. Lots marked image were supplied as scans; their values were transcribed and the original document is linked.
If a lot does not resolve
The library covers the lots currently in circulation. If the number on your vial is not listed, or the certificate does not match what is printed on the label, stop using the material and contact us at info@metrapeptides.com with the lot number and a photograph of the label.
One lot number can cover several fill sizes — a 10 mg and a 20 mg vial may share a lot yet be tested separately, so check the strength alongside the number.
Why testing is independent
A supplier testing its own material and publishing its own numbers is asking you to take purity on trust. We use a third-party accredited laboratory precisely so that the analytical result does not depend on our word, and so the record exists somewhere we cannot edit it.
Certificates are supplied with every order and remain available in the library for the life of the lot.
