PeptideBase reports these lab-published figures and does not itself test, endorse, or certify any product. Confirmed by lab results were matched against Janoshik Analytical's own records — either the lab served the document, or its own hosted copy matches ours byte for byte. For every other result the badge states what is known about the lab: that it can be checked and no result is recorded yet, that it can't be checked, or that we have not reviewed it.
