Answered from the file

Paramount Peptides verifies where Nexaph does not on: certificates tied to a specific lot; identifiable company (address or phone). Tally: Nexaph 6 of 8, Paramount Peptides 8 of 8. We do not declare a winner; the ledgers are printed so you can weigh the gaps yourself.

Do both publish a certificate anyone can open?

Nexaph: yes, lot-specific not verified. Paramount 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.
