# Oath Peptides product range rating: 4/5 (Grade A-) — part of the Oath Peptides ratings rubric > Oath Peptides product range rating scored 4/5 (Grade A-) within the Oath Peptides ratings rubric. GLP, repair, and nootropic class coverage with multiple blends. Approximately 40 peptides per peptiderecon. _CATEGORY 3 OF 4 — PRODUCT RANGE — WEIGHT 20%_ ## Oath Peptides Product Range Rating: Catalog Breadth and Depth Scored. Score: 4 / 5. Letter grade: A-. Strong class coverage and unusual blend availability for a third-party-tested vendor; catalog size narrower than the largest competitor catalogs. **Score: 4 / 5 — Grade A- (weight 20%)** ## How the product range category was scored The Oath Peptides product range rating, on this rubric, is 4/5 — high but not at the ceiling. The product range rubric is built from five documented inputs: class coverage, blend availability, dose variety per peptide, visible catalog size, and comparative narrowness against the broader market. Three of those inputs land at the top of the band; two land a step down, which is what drops the category from 5/5 to 4/5. This is the lower-weighted category alongside value (20% each) because catalog breadth matters less than testing rigor in research-peptide markets. A vendor with rigorous testing on a narrower catalog is more useful than one with weaker testing on a wider catalog. But catalog breadth is not nothing — a vendor whose catalog excludes the peptide class a researcher needs is not, for that researcher, a viable option. ## INPUT — Class coverage **Value:** Multiple peptide classes represented. GLP-class metabolic peptides (Tirzepatide, Retatrutide). Repair-class peptides (BPC-157, SS-31). Nootropic peptides (Selank). **Source:** Oath's public COA archive (verified subset captured May 2026), Peptide Protocol Wiki vendor listing (which notes Oath as one of few vendors with a 'complete GLP-1 lineup' covering semaglutide, tirzepatide, retatrutide). **Disposition:** Top-of-band. The three-class coverage — metabolic + repair + nootropic — is the rubric's strongest position. A vendor covering only one class sits two steps down. ## INPUT — Blend availability **Value:** Multiple combination blends. WOLVERINE blend (BPC-157 + TB-500). Tesamorelin + Ipamorelin. BPC-157 + TB-500 + GHK-Cu. BPC-157 + TB-500 + GHK-Cu + KPV. **Source:** Oath's public COA archive (verified subset), corroborated across third-party listings. **Disposition:** Top-of-band. Blend availability is the rubric's most differentiating product-range input because blends are uncommon among third-party-tested vendors. A vendor producing only monomers would sit a step down on this input alone. Oath's blends are tested under the same program as the monomers — WOLVERINE blend at 99.39% latest purity, Tesamorelin+Ipamorelin at 99.43% latest — which means the blend availability is not a 'tested less rigorously' exception but a full-program inclusion. ## INPUT — Dose variety per peptide **Value:** Multi-dose options on most verified entries. BPC-157 in 5mg and 10mg. Tirzepatide in 10mg, 20mg, 30mg. Selank in 5mg and 10mg. Tesamorelin + Ipamorelin in 6/2mg and 10/2mg. **Source:** Oath's public COA archive (verified subset). **Disposition:** Top-of-band on the verified subset. Multi-dose availability means a researcher can size to their specific study without buying excess inventory. ## INPUT — Visible catalog size **Value:** Selected verified subset of 9 entries in our captured fact pack. Full catalog is larger than this verified subset; peptiderecon characterizes the full catalog as approximately 40 peptides. **Source:** Oath's public COA archive (catalog visible without checkout), peptiderecon comparison page. **Disposition:** Upper-half-of-band, but not top. Approximately 40 peptides is a meaningful catalog — large enough to serve most research applications, narrower than the largest competitor catalogs. We do not claim a specific full-catalog count because the captured verified subset is smaller than the full catalog; we cite peptiderecon's 40-peptide figure as a third-party characterization rather than asserting it as a verified count. ## INPUT — Comparative narrowness against the broader market **Value:** peptiderecon characterizes Oath's catalog at approximately 40 peptides versus competitor catalogs of 50-150+. **Source:** peptiderecon head-to-head comparison page. **Disposition:** Upper-half-of-band, but not top. This is the input that pulls the category score from 5/5 to 4/5 — every other input lands at the top, but catalog narrowness against the broader market is real. We name no specific competitor vendors; what is editorially supportable is the peptiderecon characterization of the gap. One honest caveat from public discourse: an oath.reviews reviewer (hannah408, four-star) noted Retatrutide was 'out of stock for a while.' Stock availability is separable from catalog breadth — the catalog includes the entry; inventory does not always have it on hand. The rubric does not score inventory consistency. ## What independent reviewers say about the product range **peptiderecon** ranks Oath #1 in its head-to-head and writes that 'for most US-based researchers working with common peptides and prioritizing quality, speed, transparency, and service, Oath Peptides delivers the best overall value.' **Peptide Protocol Wiki** characterizes Oath as 'one of few vendors with a complete GLP-1 lineup' (semaglutide, tirzepatide, retatrutide) — significant because GLP-1-class metabolic peptides are the highest-search-volume research-peptide category in the current market. The net rating, weighted across the five inputs and corroborated by the two independent characterizations, supports 4/5 with letter grade A-. ## References [1] Oath Peptides COA archive (public batch-level lab report archive on the brand site; searchable by peptide name, batch number, or CAS number).
