// certificates
every lot, published.
Certificates are indexed by lot number, not by product. A certificate that cannot be tied to the batch in your hand is a stock document — find your lot number on the vial label and look it up here.
// products with published certificates
How to read one. Check four things before anything else: that the lot number matches
your vial, that the test date is recent, that the laboratory is accredited and its scope
covers the methods used, and that the contamination panel is present rather than omitted.
our index publishes a free tool that grades any certificate against those criteria.
