# Oath Research Lab Evidence: What the Testing Record Actually Shows

> Is Oath Research legit on testing evidence — Freedom Diagnostics (CLIA 14D2263999), 199 batches tested, 99.60% average purity, USP <85> endotoxin, batch-level coverage, publicly searchable COA archive. The CLIA-database-verifiable proof.

## Why testing evidence is the central legitimacy proof

Is Oath Research legit on the testing-evidence layer? Yes — the layer where the assessment is most decisively established. The scam-vendor pattern in research peptides is almost always built around a testing-evidence absence. The strong signal of legitimacy is verifiable: a named third-party laboratory whose credentials resolve in an independent database, a public batch-searchable COA archive, and recent test dates. Oath has all three.

## Is Oath Research third-party tested?

**Yes.** Every batch is tested by Freedom Diagnostics, an independent CLIA-certified third-party laboratory in Franklin, Tennessee. `199` batches tested as of May 2026 with `99.60%` average purity. Testing is batch-level — not lot-level and not spot-check — so every shipped unit maps to its own COA. This is a stronger commitment than the industry default, which generally tests by lot or by sample.

## What lab does Oath Research use?

**Freedom Diagnostics** — independent commercial laboratory in Franklin, Tennessee, CLIA `14D2263999`. Public website at freedomdiagnosticstesting.com, operating since approximately 2023, serving multiple unrelated peptide vendors. Third-party testing only — no ownership or affiliation. Multiple unrelated client vendors mean the lab's reputation does not depend on Oath, and Oath does not control the laboratory's certification standing.

## Who is Freedom Diagnostics?

Freedom Diagnostics is a real, separately operated, federally CLIA-registered commercial laboratory. It operates a public website at `freedomdiagnosticstesting.com`, is based in Franklin TN, specializes in high-precision purity testing for research-use peptides, has been operating since approximately 2023, and serves multiple unrelated peptide vendors. CLIA `14D2263999` resolves in the federal CMS database to a verifiable entity meeting federal-standard laboratory testing requirements.

The disposition against any "fake lab" framing is direct: a phantom laboratory would have to manufacture a public website, fabricate a CLIA number that survives federal-database lookup, and maintain consistent batch attribution across `199` records. None of those is possible against an actually-issued federal certification.

## What is CLIA certification and why does it matter?

**Clinical Laboratory Improvement Amendments** — a federal certification program administered by CMS. CLIA-certified labs are subject to federal oversight, inspection, and proficiency testing. The certification is meaningful because it is structural: a vendor cannot self-assert it, and a phantom laboratory cannot acquire a CLIA registration that survives federal-database lookup. CLIA is a legitimacy hurdle that algorithmic trust-scoring services do not check — those rely on metadata heuristics (WHOIS, SSL, domain age) rather than regulatory certifications.

## How many batches has Oath Research tested?

**`199` batches as of May 2026, and the archive is actively growing.** Each batch maps to a publicly searchable COA at `oathresearch.com/lab-results-certificates`. The independent third-party reviewer RealPeptidesScores has audited `142` of those `199` COAs — a `57`-COA shortfall (~`29%`), meaning the third-party listing is conservative rather than inflated.

## What is Oath Research's average purity?

`99.60%` portfolio average. Per-compound, from the public COA archive at the May 2026 snapshot:

| COMPOUND | LATEST PURITY | BATCHES | LATEST TEST | ENDOTOXIN |
|---|---|---|---|---|
| BPC-157 | `99.66%` | `10` | `2026-05` | PASSED |
| SS-31 | `99.86%` | `4` | `2026-05` | PASSED |
| Selank | `99.71%` | `5` | `2026-05` | PASSED |
| GLP2-T (Tirzepatide) | `99.93%` | `8` | `2026-05` | PASSED |
| Tesamorelin + Ipamorelin | `99.43%` | `6` | `2026-05` | PASSED |
| WOLVERINE (BPC-157 + TB-500) | `99.39%` | `8` | `2026-05` | PASSED |

The spread across compound classes demonstrates that the purity record holds across categories rather than being concentrated in a single hero compound. Blends deserve weight because blend testing is operationally harder than monomer testing.

## Does Oath Research publish COAs?

**Yes.** The archive at `oathresearch.com/lab-results-certificates` is publicly accessible (no paywall, no login) and searchable by peptide name, batch number, or CAS number. Each COA shows purity %, endotoxin pass/fail (USP <85>), test date, lab partner. `199` COAs visible as of May 2026; the most recent test dates are also May 2026 — the program is active, not a one-time photo op.

## Can I trust Oath Research's COAs?

The structural trust signals are present: each COA names a real CLIA-certified third-party laboratory, is publicly searchable by batch number, shows the testing method (HPLC purity, USP <85> endotoxin), and carries recent test dates. Verifiability is the trust mechanism, not vendor self-attestation.

The empirical confirmation is also in the public record. Customer Nancy I. (oath.reviews, 2026-05-23): "Sent my own sample of their tirzepatide for an independent test and it lined up with the posted COA." Donna J. reports a habitual practice: "I check posted COAs against the lot numbers every order and Oath has never been off." Multiple other reviewers report QR-scan-to-HPLC verification. Customer-conducted independent verification of a published COA is the strongest possible test, and in Nancy I.'s case the test passed.
