Do both publish a certificate anyone can open?

Peptide Pros: yes, lot-specific yes. Prime Peptides: yes, lot-specific yes. "Not verified" means we could not open such a document without an account or an order.

Why is there no price row?

Price carries no weight on this desk and does not appear in a ledger. A discount does not make an unverified certificate any more verifiable. The listed price position for each supplier sits in the source record on its own file.
