What's a CoA

Why the certificate actually matters

A Certificate of Analysis is a lab report for the product you're buying — not a vague promise, an actual documented result.

Purity, by HPLC

High-performance liquid chromatography testing confirms how pure the product is, expressed as a percentage on the certificate.

Identity, by mass spec

Mass spectrometry confirms the vial actually contains what it says it does — not just something pure, but the right compound.

One certificate per product

Click through to any product above and its Certificate of Analysis is right there — no lot numbers to track down.
