## Start with the lot report

A supplier review is a summary. The original report for the relevant lot is the evidence. Check its product and lot identifiers, laboratory name, accession number, report date, methods and results. Do not treat one report as proof about a different lot.

## What these links establish

Peptriva makes product, testing and policy information available for a reader to inspect. The strength of a particular claim depends on the underlying document. A laboratory report is evidence about the sample tested; a supplier statement about its process is a first-party statement.

## What they do not establish

This affiliated reading list is not a new independent audit, a market-wide ranking or proof that Peptriva is the best vendor. Our sister publications share the same ownership and evidence base. Read them as related commentary, not separate confirmations.
