Every batch, on the record.
Look up the certificate of analysis for any compound we sell. Match the lot number on your vial to its report.


Scan the vial. See its COA.
Every vial label carries a QR code. Point your phone camera at it to open the certificate of analysis for that batch.
- Find the QR code on the vial label
- Scan it with your phone camera
- See the lab report for your batch
Read a COA in 60 seconds.
A certificate of analysis is the lab’s report card for one batch. Tap a step to see where it sits on the page. Many of our reports also include endotoxin, heavy-metal and sterility testing, though not every report covers all three.

Illustrative example for learning purposes only. It is not a real test result. Actual COAs for each lot are in the COA Portal.
What a trustworthy COA looks like.
Lot numbers that match
The lot on the report should match the lot on your vial. A generic report with no lot number tells you little.
A real, reachable lab
The lab should be named, independent and contactable. Use the report ID or QR code to confirm the report with them.
Identity and quantity, not only purity
Purity alone doesn’t prove what’s in the vial. Look for mass-spec identity and a measured amount per vial too.
