Why this page exists
A purity figure printed on a label is a claim. A certificate you can pull up yourself, against the specific batch in front of you, is evidence. The difference is the entire reason SERVIAM exists, so it would be strange not to give you somewhere to actually check.
If a lot number does not resolve here, that is worth taking seriously. Stop, and send us a photograph of the label.
