Question 1

How do you test purity?

Accepted Answer

We confirm purity with HPLC analysis and compound identity with LC-MS analysis, for every batch before it goes on sale.

Question 2

Who performs the testing?

Accepted Answer

Testing is done by an independent laboratory that doesn't work for us, so the result isn't our own assessment.

Question 3

Where is the COA document?

Accepted Answer

The COA is available on every product page and included in the box, matched to the vial's batch number.
