# References — Oath Research Rating

> Citations and source list for the Oath Research Rating — primary records, independent vendor-scoring sites, review aggregators, and verification of the lab partner's CLIA registration.

## Primary records

1. Oath Research COA archive — publicly searchable by peptide name, batch number, or CAS number, with no paywall or account requirement. Referenced by name in this rating; not hyperlinked (independent-review hygiene).

2. Oath Research COA fields — purity %, endotoxin pass/fail, test date, lab partner identification, batch number. Referenced as primary evidence behind the testing and transparency sub-scores.

## Independent third-party laboratory verification

3. Freedom Diagnostics — independent third-party laboratory, Franklin TN, CLIA registration `14D2263999`. Lab homepage: https://freedomdiagnosticstesting.com/. CLIA registration verifiable in the CMS CLIA database.

4. CMS CLIA database — federal registry of CLIA-certified laboratories operated by the Centers for Medicare and Medicaid Services. Used to verify Freedom Diagnostics' registration independent of any vendor attestation.

## Independent vendor-scoring sites

5. RealPeptidesScores — Grade A — Recommended audit of Oath Research dated 9 May 2026. https://realpeptidescores.com/vendor/oath-research. Audit verified Freedom Diagnostics as the named lab partner with CLIA `14D2263999`; 142 COAs captured spanning 2026-01-12 to 2026-05-05 (109 within the most recent 90 days); cadence characterized as 'roughly four times the next-best vendor we audited.'

6. peptiderecon — #1 ranking in its research-peptide-supplier head-to-head, with the quoted characterization 'Oath's batch-specific QR code system represents the gold standard in testing transparency.' https://peptiderecon.com/suppliers/comparisons/oath-vs-competitors. Cited also for the 10-20% premium-over-budget-vendors framing on the value sub-score.

7. peptideprotocolwiki — 7.2 / 10 ('good, Moderate Trust') vendor profile, including independent corroboration of Oath's Gilbert AZ address and phone. https://www.peptideprotocolwiki.com/vendors/oath-peptides. Cited also for the 'complete GLP-1 lineup' characterization on the product range sub-score.

## Independent review aggregators

8. amino.reviews / oath.reviews — 4.8 / 5 across 69 verified reviews; 180 verified lab tests on file; rating distribution 5★ 57 / 4★ 11 / 3★ 1 / 2★ 0 / 1★ 0. https://oath.reviews/ (verified by https://amino.reviews/). Cited for customer-self-verification reviews (Nancy I., Jeffrey H., Donna J., Devin N., hannah408) at https://oath.reviews/reviews.

9. Trustpilot — 4.6 / 5 across 20 reviews at https://www.trustpilot.com/review/oathresearch.com. Direct WebFetch returned 403 at scrape time; data captured via Google search snippets with multiple representative reviews including the long-term repeat-purchase attestation and the explicit cost-of-rigor justification used on the value sub-score.
