# Oath Research Transparency Rating: 95 of 100 — Public COA Archive Scored

> The Oath Research transparency rating is 95 / 100 — second-heaviest weight (25%) in the Oath Research ratings. Driven by a publicly searchable batch-level COA archive (three independent retrieval axes), per-COA lab attribution, May 2026 recency, and 1:1 batch-to-COA parity.

**Category 02 — Transparency — 25% Weight**

Headline score: **95 / 100 — Top-tier**.

## Criterion breakdown

| Criterion | Score | Evidence |
|---|---|---|
| COA public access | 25 / 25 | Full public access on company's primary site. No paywall, no account creation. |
| Search depth | 20 / 20 | Three independent retrieval axes — peptide name, batch number, CAS number. |
| Per-COA detail | 20 / 20 | Every COA shows purity %, endotoxin pass/fail, test date, and named issuing laboratory. |
| Archive scope | 15 / 15 | 1:1 batch-to-COA parity (199 COAs : 199 tested batches). |
| Recency | 10 / 10 | Most recent tests dated May 2026 — same month as observation. |
| Third-party listing parity | 5 / 10 | RealPeptidesScores displays 142 of 199 COAs (~71%). |

## 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.

## What is Oath Research's transparency score?

95 of 100 — top-tier. Five of six criteria capture full points 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.

## 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). [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. [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). Second, the archive is batch-level rather than lot-level or spot-check, with 1:1 batch-to-COA parity. Third, the archive is publicly indexed by three independent axes.

The strongest available signal is customer-side independent verification. At least one customer (Nancy I., 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]

## 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.

## 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. 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.
