Methodology
Same fields, dated sources, no scores
Facts come from each laboratory's own public pages, reviewed on 11 November 2026 (America/Phoenix). Where a page did not state a fact, the cell says Not published. Re-check every number and accreditation claim before launch, because these pages change.
- Every laboratory gets the same sections: methods, pricing, turnaround, accreditation, submission, verification, limitations, and sources.
- Facts come from the laboratory’s own website. A forum price or a directory blurb is not a source.
- If the pages reviewed did not state a fact, the cell says “Not published.” It is not filled with a guess.
- There are no stars, ranks, or composite scores. Sort options are name, lowest published price, and shortest stated turnaround, with the limits printed under the table.
- Apollo Analytical is described as operating in alignment with ISO/IEC 17025, accreditation pending. Conflicting CORE and ZENITH prices are flagged for confirmation.
- Vanguard Laboratory is described as ISO/IEC 17025 accredited under A2LA certificate 6377.01, with peptide methods outside the accredited scope.
- The operator is Meridian Peptide Supply. Meridian Peptide Supply has no ownership, management, or financial relationship with Apollo Analytical or any other laboratory listed. Listings are not paid placements.
