# Oath Research Testing Rating: 97 of 100 — Scoring the Lab Program > The Oath Research testing rating is 97 / 100 — the heaviest weight (35%) in the Oath Research ratings rubric. Driven by Freedom Diagnostics CLIA 14D2263999 independence, every-batch frequency, USP <85> + HPLC scope, 99.60% average purity, and per-batch ENDO PASSED endotoxin results. **Category 01 — Testing Rigor — 35% Weight** Headline score: **97 / 100 — Category-leading**. ## Criterion breakdown | Criterion | Score | Evidence | |---|---|---| | Lab independence | 25 / 25 | Freedom Diagnostics, CLIA 14D2263999, Franklin TN. Verifiable in CMS public CLIA database. | | Testing frequency | 25 / 25 | Every batch. 199 COAs : 199 tested batches = 1:1 parity. | | Testing scope | 20 / 20 | HPLC purity + USP <85> endotoxin + composition verification. | | Average purity | 13 / 15 | 99.60% average across 199 visible batches. 2-point deduction for narrow longitudinal range. | | Endotoxin pass rate | 14 / 15 | All visible COAs marked ENDO PASSED to USP <85>. 1 point withheld pending multi-year continuous record. | ## What drives the testing rating The Oath Research testing rating lands at 97 of 100 because five separate criteria converge — and because every input is independently verifiable rather than vendor-attested. The **batch count** is 199 as of May 2026 in the company's own public archive. RealPeptidesScores' independent audit captures 142 of those COAs and still characterizes the cadence as "roughly four times the next-best vendor we audited" — about 36.3 COAs per month, with 109 of 142 falling within the last 90 days at audit time. [4] The **coverage** is every-batch. Not lot-level, not spot-check, not "representative samples." Every batch that ships has a COA in the public archive, indexed by name, batch number, and CAS number. This is rare in the research-peptide category; peptiderecon's head-to-head identifies it as "the gold standard in testing transparency." [5] The **lab partner** is Freedom Diagnostics — an independent commercial laboratory in Franklin, Tennessee, holding CLIA registration 14D2263999. CLIA is the federal credential issued by CMS; the registration number is verifiable in the public CLIA database. [3] Freedom Diagnostics serves multiple unrelated vendors and is not exclusive to Oath. > Oath's batch-specific QR-code system represents the gold standard in testing transparency. > — peptiderecon head-to-head, May 2026 ## Is Oath Research third-party tested? Yes. Every batch is tested by Freedom Diagnostics, an independent third-party laboratory in Franklin, Tennessee, holding CLIA registration 14D2263999 — verifiable in the CMS public CLIA database. [3] As of May 2026, 199 batches have been tested. ## What lab does Oath Research use? Freedom Diagnostics — an independent third-party laboratory in Franklin, Tennessee, holding CLIA registration 14D2263999. The CLIA number is verifiable in the public CMS CLIA database. Freedom Diagnostics serves multiple unrelated vendors and is not affiliated with the company under rating beyond the testing relationship. [2] ## Who is Freedom Diagnostics? Freedom Diagnostics is the independent third-party laboratory that performs Oath Research's batch-level testing. It is a real commercial lab in Franklin, Tennessee, holding CLIA registration 14D2263999 — verifiable in the CMS public CLIA database. It specializes in high-precision purity testing for research-use-only peptides and serves multiple unrelated vendors. ## How many batches has Oath Research tested? 199 batches as of May 2026, with the program actively growing month over month. RealPeptidesScores' independent audit puts the cadence at roughly 36.3 COAs per month — about four times the next-best vendor that site audited. The RPS listing currently displays 142 of the 199 COAs, which is ~29% incomplete; the company's own archive is the more complete record. [4] ## What is Oath Research's average purity? 99.60% average purity across the 199 visible batches in the public COA archive. - GLP2-T (Tirzepatide) — 99.93% across 8 batches. - SS-31 — 99.86% across 4 batches. - Selank — 99.71% across 5 batches. - BPC-157 — 99.66% across 10 batches. - Tesamorelin + Ipamorelin blend — 99.43% across 6 batches. - BPC-157 + TB-500 (WOLVERINE blend) — 99.39% across 8 batches. All listed test dates fall in May 2026, and every COA shows an ENDO PASSED result. ## What is USP <85>? USP <85> is the United States Pharmacopeia chapter that specifies the bacterial endotoxin test (BET) used to detect endotoxins in pharmaceutical materials. Endotoxins are fragments of gram-negative bacterial cell walls; even trace levels can trigger fever or inflammatory response when introduced parenterally. Oath Research tests every batch to this standard; every visible COA in the public archive marks ENDO PASSED. [14] ## What does USP <85> endotoxin testing tell you about Oath Research? USP <85> compliance — performed by a CLIA-certified third-party lab on every batch — is a category-leading signal. Many vendors do not test for endotoxin at all. In our rubric, this evidence scores into both the testing-scope criterion (20 points) and the endotoxin-pass-rate criterion (14 of 15 points). Together those two criteria account for 34 of the 35 weight points allocated to the testing category. ## Does Oath Research test every batch or only some? Every batch — not lot-level, not spot-check. The 199-batch count in the public COA archive corresponds to 199 separate batch-level test records, each with its own purity %, endotoxin result, test date, and lab partner. The 1:1 batch-to-COA parity here is the verifying signal. ## Why the ceiling is 97 and not 100 Our methodology does not assign a perfect score on any criterion where the underlying evidence is younger than two years. The Oath Research testing program is roughly ten months old at the time of writing. The cadence is high, the methodology is sound, the lab partner is real and independent, the purity numbers are tight — but the program has not yet accumulated the multi-year longitudinal history that would justify a maximum. As the testing archive extends past 24 months of continuous output without methodology drift or lab-partner turnover, the ceiling will lift. ## References [1] Oath Research COA archive.
