Peptique COA verification library
Batch documentation.
Clearly verified.
Every released lot has a Certificate of Analysis from an independent laboratory. Search by compound, strength or lot number, open the report, and match it to the lot printed on your vial. Results apply to the tested lot only.

Report-specific results
Each report describes the sample and lot that was tested. Results do not transfer to other lots, strengths or formats.
Cannot find your lot?
Send the lot number and a photo of the label to COA support and we will locate the report or tell you when it will be published.
Specimen documents
Where a lot's report is pending, the library shows a specimen of the certificate layout with every result marked pending. A specimen is not a result.
How to read a Peptique COA
What matters most
Does the lot on the report match the lot on the vial?
That is the first check. A report for a different lot tells you nothing about the material in hand.
Which laboratory issued it, and can it be verified there?
Every published report names the laboratory and carries the laboratory's own accession or verification code, which can be checked on the laboratory's site.
What was tested?
Identity by LC-MS, purity by RP-HPLC, net content per vial against the labeled strength, endotoxin by LAL, sterility by USP 71, heavy metals by ICP-MS, and appearance.
Why might a report show another company name?
It should not. Peptique submits samples under its own name. If a report shows anything else, contact COA support before relying on it.
Where are the Safety Data Sheets?
A GHS 16-section Safety Data Sheet is published per compound alongside the lot reports as lots are released.
