SUB-SCORE — PRODUCT RANGE — 15% WEIGHT

8.0 / 10

Above-average for a young vendor

Strong coverage across peptide classes; peptideprotocolwiki characterizes Oath as 'one of the few vendors with a complete GLP-1 lineup.' Capped at 8.0 because peptiderecon's head-to-head notes ~40 peptides versus 150+ at the largest competitors.

What drives the product range sub-score

The Oath Research product range rating sits at 8.0 / 10 because the catalog satisfies the breadth-by-class test while falling short of the absolute-size test. Four peptide classes are represented, each with at least one publicly-tested product, and the GLP-class lineup is unusually complete for a young vendor — peptideprotocolwiki characterizes Oath as 'one of the few vendors with a complete GLP-1 lineup' (Semaglutide via blends, Tirzepatide as GLP2-T, Retatrutide as GLP3-R). The absolute size, on the other hand, is modest: peptiderecon's head-to-head pegs Oath at roughly 40 peptides versus 150+ at the largest competitors. We do not penalize a young vendor for not having a 150+ catalog — but we do not assign a top-band score either.

What peptides does Oath Research sell?

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 — Oath's site shows more SKUs than the publicly captured snapshot — but the visible coverage is sufficient to establish four-class representation.

The catalog by peptide class

The class-level breakdown of the visible catalog evidence:

  • GLP-class incretin peptides. GLP2-T (Tirzepatide; CAS 2023788-19-2; offered at 10mg, 20mg, 30mg; 99.93% latest purity across 8 tested batches — the highest visible purity figure in the captured subset). GLP3-R (Retatrutide; CAS 2381089-83-2) — present in the catalog and explicitly audited by RealPeptidesScores at >99% purity on Batch A1226 (29 April 2026). Semaglutide is covered via combination blends.
  • Repair / regenerative peptides. BPC-157 (CAS 137525-51-0; offered at 5mg and 10mg; 99.66% latest purity across 10 tested batches — the highest test-count product in the captured subset). TB-500 appears as part of the WOLVERINE multi-compound blend (CAS 137525-51-0; 77591-33-4; 99.39% latest purity across 8 tested batches at 5/5mg). SS-31 (CAS 736992-21-5; 99.86% latest purity across 4 batches at 10mg).
  • Neuroactive / nootropic peptides. Selank (CAS 129954-34-3; offered at 5mg and 10mg; 99.71% latest purity across 5 batches).
  • Multi-compound blends. WOLVERINE (BPC-157 + TB-500) and Tesamorelin + Ipamorelin (CAS 218949-48-5; 170851-70-4; 99.43% latest purity across 6 batches at 6/2mg and 10/2mg). The Tesamorelin+Ipamorelin Batch B0526 was independently audited by RealPeptidesScores at >99% purity on 5 May 2026 — useful cross-corroboration between Oath's own COA and the third-party audit.

How catalog breadth interacts with testing depth

Our methodology assigns product range only 15% of the composite weight, well below testing and transparency. The reason is editorial: a narrow catalog tested thoroughly is preferable to a wide catalog tested loosely. A vendor with 200 SKUs and no public COAs is not, by our reading, offering a stronger product than a vendor with 40 SKUs and a CLIA-lab-attested COA for every batch. Oath's 40-peptide catalog is the smaller side of the trade; its 199 batches and every-batch coverage are the larger side. The 8.0 sub-score is the honest readout of that trade — above-average for a young vendor, capped below top-band because the absolute size is modest.

What is the Oath Research product range score?

Above-average for a young vendor — not top-band. The catalog covers GLP-class incretin peptides, 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 — which is why this sub-score is rated above-average rather than top-band, and why product range carries 15% weight rather than the heavier weight assigned to testing and transparency.

Stockouts and catalog churn

Even amid generally positive review signal, the product range sub-score has to absorb at least one honest mixed input. From a representative amino.reviews verified review:

Quality is great when you can get it. Retatrutide was out of stock for a while.

A young catalog can run out of SKUs the manufacturing pipeline has not yet stabilized; that is a category-level reality rather than an Oath-specific failing. We note it here, in the product range section, because that is where the input belongs editorially — neither inflated into a complaint that disqualifies the vendor nor papered over. Stockouts are real; they reduce product-range fluency without reducing testing rigor.
