Which peptide testing laboratories let you verify a report yourself?

Freedom Diagnostics Testing and Janoshik Analytical publish public lookups. A certificate from those laboratories carries an identifier that can be entered on the laboratory's own site, returning the report from the laboratory rather than from the vendor. 304 of the 569 certificates indexed here were signed by one of them.

Is a laboratory being named on a COA enough?

It is the minimum, not the whole test. A named laboratory that is not the vendor, an assayed mass printed against the labelled mass, and a lot number matching your vial are the three things that make a certificate checkable. A laboratory that also publishes a lookup removes the last reason to take the vendor’s word for any of it.

How to read this table

Certificate count is how many lots that laboratory signed among the documents we have read. It reflects which vendors we cover and how much each publishes, so it measures our coverage of the laboratory, not the laboratory’s size.

Mean purity is the average of what those certificates reported. It describes the samples the laboratory received. A high figure says those lots assayed well; it is not a rating of the laboratory and cannot be read as one.

Accreditation is attributed narrowly. A vendor that records ISO/IEC 17025 accreditation for its testing lab tells us which laboratory is accredited only when it uses one laboratory. Where a vendor uses several, its accreditation claim is left unattributed rather than shared out among them, because the certificate does not say which bench it belongs to.
