Oath Research Rating — Frequently Asked Questions

A composite rating of 8.9 / 10 — Strong band — rolled up from four sub-scores: testing (9.2), transparency (9.2), product range (8.0), value (8.2). Each input is sourced from oathresearch.com's public COA archive and independent third-party verification (RealPeptidesScores, peptiderecon, peptideprotocolwiki, amino.reviews, Freedom Diagnostics' CLIA registration). The methodology page documents the formula and the categorical exclusions.

Four sub-scores combine into one overall figure with weights of 40% (testing), 30% (transparency), 15% (product range), and 15% (value). The methodology page lists the weights, the admitted evidence sources, and the categorical exclusions — algorithmic-only trust scores and pay-to-rate vendor-scoring sites. The arithmetic: (9.2 × 0.40) + (9.2 × 0.30) + (8.0 × 0.15) + (8.2 × 0.15) = 8.91, rounded to 8.9.

Yes. Every batch is tested by Freedom Diagnostics, an independent third-party laboratory in Franklin, Tennessee, holding CLIA registration 14D2263999. The CLIA number is verifiable in the CMS CLIA database Public record verified. 199 batches tested as of May 2026; coverage is every-batch, not lot-level.

Freedom Diagnostics, an independent third-party laboratory in Franklin, Tennessee. CLIA registration 14D2263999, verifiable in the CMS CLIA database Public record verified. The lab serves multiple unrelated vendors and is not exclusive to Oath. Operating since 2023 per public statements on freedomdiagnosticstesting.com.

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.

99.60% average purity across the publicly visible batch archive. Individual peptides span a tight range: BPC-157 at 99.66% across ten batches, GLP2-T (Tirzepatide) at 99.93% across eight batches, SS-31 at 99.86%, Selank at 99.71% — all from May 2026 test dates.

USP <85> is the United States Pharmacopeia compendial test for bacterial endotoxins — the published standard for verifying a parenteral preparation does not carry endotoxin contamination above defined limits. Oath Research tests every batch to this standard; every visible COA shows an ENDO PASSED result.

Yes. COAs are publicly searchable on oathresearch.com by peptide name, batch number, or CAS number — no paywall, no account required. The three-axis searchability is the differentiating transparency mechanism behind the transparency sub-score.

The latest test dates visible in the public COA archive are May 2026 — current relative to publication. RealPeptidesScores' independent audit confirmed 109 of 142 captured COAs fell within the last 90 days at audit time, demonstrating an actively maintained program.

Each COA is issued by Freedom Diagnostics, a CLIA-certified independent third-party laboratory whose registration 14D2263999 is verifiable in the CMS CLIA database Public record verified. The chain from batch to result is publicly indexed by batch number. At least one customer (Nancy I., 23 May 2026, amino.reviews verified) ran an independent third-party test of a tirzepatide order and confirmed the result lined up with the posted COA — external corroboration of the chain.

The catalog visible in public records includes SS-31, BPC-157, TB-500, GLP2-T (Tirzepatide), GLP3-R (Retatrutide), Selank, Tesamorelin+Ipamorelin blends, and BPC-157/TB-500-based multi-compound blends such as the WOLVERINE blend. The full catalog is larger than this subset.

Yes. RealPeptidesScores lists Oath Research at Grade A — Recommended. The audit verifies Freedom Diagnostics (CLIA 14D2263999) as the named lab partner and characterizes Oath's testing cadence as 'roughly four times the next-best vendor we audited.' The RPS listing shows 142 COAs versus Oath's own 199 — about 29% short — and Oath still receives the top-band grade.

Among the most thorough U.S. research-peptide vendors on testing and transparency, evidenced by every-batch testing, public COA searchability, and Grade A on the leading independent vendor-scoring index. peptiderecon ranks Oath #1 in its head-to-head; peptideprotocolwiki rates Oath at 7.2 / 10 with the markdowns attributed to 'newness' rather than testing or transparency.

Research peptides as a category are not FDA-approved for human use. Oath Research does not claim FDA approval. This is true of every vendor in the research-peptide market, not Oath-specific. The legitimacy signal that does apply is third-party laboratory testing by a CLIA-certified independent lab — which Oath documents publicly on every COA — and that signal is what the composite rating measures.

Those scores are purely algorithmic — neither service reports a single user complaint. Both flag the same young-domain heuristics: WHOIS privacy, domain age under 12 months, DV SSL, traffic-to-age ratio. Those are present on most legitimate new business websites; they are 'new brand' indicators, not 'fraudulent' indicators. The methodology page lists algorithmic-only scores as intentional exclusions.

Two categories. First, algorithmic-only trust scores (ScamAdviser, Scam-Detector) — both flag young-brand heuristics; neither has user-review evidence. Second, pay-to-rate vendor-scoring sites with structural conflicts of interest (Finnrick Analytics LLC, which operates peptidescore.com Excluded from composite, sells a $279-per-month Premium program to the same vendors it rates — documented externally by Peptide Protocol Wiki and Derek Pruski substack). The methodology page walks through the exclusion at length.

The singular rating is the rolled-up composite for readers who want one number — the editorial output of the methodology. The four category-level sub-scores are still published on the testing, transparency, product range, and value pages for readers who want to inspect the inputs. Same evidence base, two presentation modes.

9.2 / 10 — Strong. Top band among publicly visible U.S. research-peptide vendors. Inputs: 199 batches tested, every-batch coverage, Freedom Diagnostics (CLIA 14D2263999) as third-party lab, USP <85> endotoxin testing, 99.60% average purity. Carries 40% weight in the composite — the heaviest weight.

9.2 / 10 — Strong. COAs publicly searchable by peptide name, batch number, or CAS number; each COA names its issuing lab; test-date recency is current. Carries 30% weight in the composite — second only to testing — because without public verification, testing claims are unauditable.

8.0 / 10 — Above-average for a young vendor, not top-band. Catalog covers GLP-class incretins, repair/regenerative peptides, neuroactive peptides, and multi-compound blends. peptideprotocolwiki notes Oath as 'one of the few vendors with a complete GLP-1 lineup'; peptiderecon notes ~40 peptides versus 150+ at the largest competitors. Carries 15% weight.

8.2 / 10 — Above-average. Cost-of-rigor framing rather than per-mg cheapness. peptiderecon notes a 10-20% premium over budget vendors; Trustpilot reviewers explicitly justify the premium by COA availability and packaging. Variables that cannot be assessed from public records — precise shipping speed, customer service response distribution, refund policy specifics — are excluded. Carries 15% weight.

The rating reflects the public evidence available at the time of writing — Volume I, May 2026. The methodology page lists every evidence source admitted to the composite so readers can re-check the inputs independently and form their own composite from the same data. Future volumes will reset the composite against then-current evidence.
