Reader questions

Answered from the file
Ascension Peptides or QSC: which file verifies on more checks?

Ascension Peptides verifies on 8 of 8 against 5. The two ledgers differ on 3 of 8 checks. Ascension Peptides verifies where QSC does not on: third-party laboratory testing; certificates of analysis open to the public; certificates tied to a specific lot. Tally: Ascension Peptides 8 of 8, QSC 5 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?

Ascension Peptides: yes, lot-specific yes. QSC: not verified, lot-specific not verified. "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.
