Peptide COA library

What a certificate here is

Each one is issued for a single lot by ILS Laboratories, an independent laboratory — not by us — and the lot number on it is the one printed on the vial. Every certificate here reports HPLC purity, sterility, bacterial endotoxin, heavy metals and a fentanyl screen. Most also report identity against a reference standard and net peptide content. The certificate page for a lot shows its full panel, result by result. How each test is run, and what its result does and does not tell you, is set out on the testing page.

How to check one with the laboratory

1. Open a certificate from the table. Its access code is printed in the header of the PDF and shown on its page here.
2. Enter that code on the issuing laboratory's own verification page — ils-lab.com/verify. Where the table shows “Laboratory's record”, that link opens the same record directly.
3. The laboratory shows you its own record of that lot — the product, the lot number, the results and the signatory. We do not host that page and cannot edit it.
