Reader questions

Answered from the file

Nexaph or Peptide Pros: which file verifies on more checks?

Peptide Pros verifies on 7 of 8 against 6. The two ledgers differ on 3 of 8 checks. Nexaph verifies where Peptide Pros does not on: third-party laboratory testing. Peptide Pros verifies where Nexaph does not on: certificates tied to a specific lot; identifiable company (address or phone). Tally: Nexaph 6 of 8, Peptide Pros 7 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. Peptide Pros: 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.
