Certificate lookup
Type the lot number on the vial.
Every certificate is addressable by lot. No account, order number or email address is needed to read one. The lot is printed on the vial label and starts with GBX-.

Certificates outlive the lot
A certificate stays online after the lot sells out and after a product is discontinued.
One lot, one certificate
We don’t re-use a certificate across lots or ship under a “representative” result. The number on your vial resolves to the material in your vial.
What a certificate covers
Identity by mass spectrometry, purity by HPLC, screening results, and the dates and lab. It says what was measured, and what wasn’t.
