How to verify a certificate
- Find the lot number on your vial. It is printed on the label, for example KB-17790.
- Look it up. Enter it at igf1lr3.bio/verify, or open the matching lot in the COA archive.
- Check the lab's own record. Go to portal.ils-lab.com (or scan the QR code on the certificate) and enter the lot's verification access code, listed on its lot page, to view the laboratory's own copy of the certificate.
- Compare the details. Lot number, the laboratory’s reference numbers, purity and dates should match exactly.
What a certificate of analysis does and doesn't show
- A COA reports the identity, purity and content of the specific sample tested, on its test date. Results apply to that lot only.
- HPLC purity measures the main peak relative to other detected components. It does not identify the peak on its own; the separate identity test (HPLC retention-time match) does that.
- A retention-time match shows the main peak behaves like the reference standard under one method. It is not a mass or structure measurement.
- Endotoxin and microbial results apply only where those tests appear on the certificate. Lots without them are marked "Not tested".
- A certificate does not establish stability after the test date or suitability for any particular purpose.
