Peptide testing lab directory: how to verify a COA with each lab
By Vitality Chems · Published · updated · vendor-authored explanatory note
Short answer
A certificate of analysis only counts once the laboratory that issued it confirms it. This directory lists 9 independent labs that commonly appear on research-peptide certificates, each lab's own verification page (7 have a public lookup), the exact code to enter, and how to compare the lab's record with your copy. Every link was opened on 2026-11-12. It is free to cite and available as JSON.

| Laboratory | Verify a report | What to enter | How to confirm |
|---|---|---|---|
| Freedom Diagnostics Testing | freedomdiagnosticstesting.com/search-for-your-coa-based-on-the-unique-accession-number/ | Search Code (first four characters of the client name followed by the accession number), the accession number alone, or the client company name | Enter the Search Code from the top-right table of the certificate with no spaces, open the PDF the lab returns, and compare it field by field with your copy. |

The method that works for any lab
Find the lab name and the report's unique code on the certificate. Go to the lab's website yourself by typing its address, not through a link, QR code or file supplied by the seller, because a link can point to a look-alike page.
Enter the code exactly as printed, open the record the lab returns, and compare every field with your copy: client, sample description, lot, dates, method and each numeric result. Any difference means the copy you hold is not the report the lab issued.
- Run a control: change one character of the code and look it up again. A lookup that answers every code proves nothing.
- Match the lot on the certificate to the lot printed on the vial label.
- Save the date you checked and a screenshot of the lab's record with your batch records.
What a confirmed report does and does not show
A match shows that the lab issued that document to the client named on it and that your copy agrees with the lab's copy. It does not show that a particular vial came from the tested sample; that link runs through the lot number on the label and the seller's records.
A report covers only the tests it prints. If endotoxin, sterility or heavy metals are not on it, they were not reported. Accreditation also has a scope: an ISO/IEC 17025 certificate applies only to the methods listed on the accreditation body's scope document.
How this directory is maintained
Each lookup URL was opened on the date shown. Addresses appear only where the lab's own website prints one. Labs are listed for their verification method, not ranked, and no lab endorses Vitality Chems. Corrections from labs are welcome at hello@vitalitychems.com.
Frequently asked
How do I verify a Janoshik COA?
Open janoshik.com/verification in a browser, enter the task number and the verification key printed on the report exactly as shown, and compare the report the lab returns with your copy.
How do I look up a Freedom Diagnostics certificate?
Use the Certificate of Analysis Lookup on freedomdiagnosticstesting.com and enter the Search Code from the top-right table of the certificate (the first four characters of the client name plus the accession number), without spaces.
What if a lab has no public lookup?
Scan the QR code if the report has one and check the domain it opens, or ask the lab to confirm the report using contact details from the lab's own website, never from the seller.
Can I cite or reuse this directory?
Yes. It is published under CC BY 4.0 and available as JSON at /peptide-testing-labs.json. Please link to this page.
Is a QR code on a COA enough proof?
Not by itself. Scan it, then check that the page you land on is the lab's official domain and that its record matches your copy.
