Certificates of Analysis

Every lot we list is assayed by an independent laboratory before it goes on sale. Purity is measured by reverse-phase HPLC-DAD against the labelled claim, and identity is confirmed by retention time and UV spectral match against a reference standard. Certificates are published here as they are issued, and the paperwork for the exact lot you receive ships with your order.
