- power_cut_pia — the three way match is vial, certificate, invoice. if all three agree you have something 18:34
if you only read one line on a certificate, read the lot number. if you read two, read the assay
is a supplier certificate worth anything on its own
no lot number on this certificate, does that make it worthless
net peptide is gross mass minus water minus counterion. that is why 11.4mg of powder can be a correct 10mg vial
update from 12 months ago: started asking every supplier for water content and about half now include it
not evidence on its own
