Independent testing, on record
Every batch we sell is tested by an independent third-party laboratory before it goes on sale, and each report is published for you to review once it is back and lot-matched.
HPLC purity & identity
High-performance liquid chromatography confirms both the purity and molecular identity of each batch.
Endotoxin testing
Batches are screened for endotoxin levels as part of the standard testing panel.
Testing partner
Testing is performed by MZ Biolabs, an independent third-party laboratory, on a per-lot basis.
COA Library
Published Certificates of Analysis are organized by product and lot number in our COA Library. We’re continuing to add reports as new batches are tested — if you need a report for a product that isn’t listed yet, contact us and we’ll send it directly.
