Certificates of analysis
HPLC purity and mass spectrometry identity for every batch. The certificate names the batch it belongs to, and that number is printed on your vial, so the material you receive can be checked against the record rather than against the product line in general.

FAQ
Is testing in-house or independent?
By a third-party laboratory, and the certificate names it. An in-house number nobody else has checked is worth less than an independent one.
What purity do you hold to?
At least 98% by HPLC. Batches below that are not sold.
How do I get the certificate for my batch?
Ask with your order number and we send the certificate for the batch you were sent. If you need to see the current batch before ordering, ask and we will send it first.
