Oath Research Transparency Rating: Public COA Archive Scored

95 / 100. Top-tier. The second-heaviest input to the Oath Research ratings — because without public verifiability, testing claims are unauditable, and unauditable claims score zero.

95 / 100

COAs publicly searchable on the company’s primary site by peptide name, batch number, or CAS number — no paywall, no account required. Each COA names Freedom Diagnostics as the issuing lab. Latest tests May 2026. RealPeptidesScores displays 142 of the 199 COAs, confirming the company’s own archive as the more complete record.

Criterion breakdown

  • COA public access
    25 / 25

    Full public access on the company’s primary site. No paywall, no account creation, no gated portal.

  • Search depth
    20 / 20

    Three independent retrieval axes — peptide name, batch number, CAS number. Top-tier criterion fulfillment.

  • Per-COA detail
    20 / 20

    Every COA shows purity %, endotoxin pass/fail, test date, and named issuing laboratory (Freedom Diagnostics).

  • Archive scope
    15 / 15

    1:1 batch-to-COA parity (199 COAs : 199 tested batches) — no spot-check pattern.

  • Recency
    10 / 10

    Most recent tests dated May 2026 — same month as observation. Program is active, not historical.

  • Third-party listing parity
    5 / 10

    RealPeptidesScores displays 142 of 199 COAs (~71%). The gap reflects RPS’s audit cycle running behind Oath’s cadence, not a transparency knock; partial credit pending future re-audit.

What drives the transparency rating

The Oath Research transparency rating lands at 95 of 100 because the public COA archive does three things at once that most vendors do one of at best.

First, it is public — no paywall, no account creation, no gated portal. Anyone with a browser and a batch number can pull the certificate.

Second, it is multi-axis searchable. The same archive can be queried by peptide name, by batch number, or by CAS number. Three independent retrieval paths matter because a customer who knows only one of those values can still verify a lot — and because three independent indices are harder to fake at scale than one curated front page.

Third, it is lab-attributed. Every COA names Freedom Diagnostics as the issuing laboratory, not “a third-party lab” generically. Naming the lab makes the chain externally checkable: a reader can look up CLIA 14D2263999 in the CMS database and confirm the lab exists, is licensed, and is independent of the company under rating.[3] RealPeptidesScores’ Grade A audit explicitly verified this chain at scrape time.[4]

What is Oath Research’s transparency score?

95 of 100 — top-tier. Five of six criteria capture full points (COA public access 25/25, search depth 20/20, per-COA detail 20/20, archive scope 15/15, recency 10/10) and the sixth (third-party listing parity, 5/10) reflects that RealPeptidesScores displays 142 of the 199 COAs the company itself publishes — the gap is a function of RPS’s audit cycle running behind Oath’s testing cadence, not a transparency knock against the company. The transparency rating carries 25% weight in the overall rubric because public verifiability is what converts a testing claim into an auditable record.

Does Oath Research publish COAs?

Yes. COAs are publicly searchable on oathresearch.com by peptide name, batch number, or CAS number — no paywall, no account required. Each COA shows purity %, endotoxin pass/fail, test date, and the named issuing laboratory (Freedom Diagnostics). This three-axis searchability is the central transparency mechanism behind the transparency rating’s top-tier score.[1]

How recent are Oath Research’s lab tests?

Tests dated as recently as May 2026 appear in the public COA archive across multiple peptides (SS-31, BPC-157, GLP2-T tirzepatide, Selank, Tesamorelin+Ipamorelin, WOLVERINE blend). RealPeptidesScores’ independent audit confirmed 109 of 142 captured COAs fell within the last 90 days at audit time — a cadence of roughly 36.3 COAs per month. Test recency demonstrates an actively maintained testing program, not a one-time launch artifact, and captures the full 10 points allocated to the recency criterion.[4]

Can I trust Oath Research’s COAs?

Three structural properties make the record verifiable rather than self-asserted. First, the COAs originate from an independent CLIA-certified third-party laboratory (Freedom Diagnostics, registration 14D2263999) — the issuing entity is independently verifiable in the public CMS CLIA database. Second, the archive is batch-level rather than lot-level or spot-check, with 1:1 batch-to-COA parity (199 COAs : 199 tested batches). Third, the archive is publicly indexed by three independent axes (peptide name, batch number, CAS number), making the chain queryable from whichever data point the reader holds.

The strongest available signal is customer-side independent verification. At least one customer (Nancy I., amino.reviews / oath.reviews, 23 May 2026) reports having sent a sample of Oath’s tirzepatide to an independent third-party laboratory for retest and confirmed the results lined up with the posted COA.[11] A customer running their own external retest and corroborating the published certificate is verification at a higher tier than reviewer attestation. RealPeptidesScores’ independent display of 142 of those COAs is a second corroboration.

Is Oath Research listed on RealPeptidesScores?

Yes. RealPeptidesScores rates Oath Research at Grade A — Recommended, with the lab partner independently verified as Freedom Diagnostics (CLIA 14D2263999). The audit summary characterizes Oath as “per-batch, portal-verifiable, and four times the cadence of anyone else we audited.”[4] The RPS listing currently displays 142 of the 199 batches Oath itself publishes — confirming the company’s own COA archive as the more complete record, with the ~29% gap reflecting RPS’s audit cycle rather than any transparency knock against Oath.

Where the five points went

The 5-point deduction in the transparency category lives entirely in the third-party-listing-parity criterion. RealPeptidesScores’ independent audit displays 142 of the 199 COAs the company itself publishes — the rubric scores third-party listing parity on the assumption that at least most of the company’s archive is independently displayed by a disclosed-methodology third party. Oath fulfills this criterion at ~71% parity, scoring 5 of 10. The half-credit reads honestly: it is a partial fulfillment, not a missing fulfillment, and the gap favors Oath because Oath’s testing cadence runs ahead of the third-party reviewer’s audit cycle. A future RPS re-audit that catches up to the full archive would lift this criterion to full points and the category to 100.
