Certificates of Analysis
Every lot, documented.
Independent purity and identity testing stands behind every product we sell.
How to find a lot’s certificate
Every product page shows that lot’s Purity (HPLC), storage condition, and batch code (its SKU) directly on the product listing — including in the Best Sellers section on the homepage. The batch code printed on your vial’s label matches what’s shown on the product page it came from.
What’s tested
Every batch is independently verified by a third-party lab using HPLC for purity and mass spectrometry for identity confirmation before it’s listed for sale.
