BENCHMARK PROFILE
Simple Peptide
Latest sync: Sep 8, 2026, 8:55 AM. Source coverage currently reflects Finnrick data.
Readers who want provider-verifiable third-party COAs across a broad catalog, confirmable code-by-code against Freedom Diagnostics with no login.
Verification is single-lab (Freedom Diagnostics) and a minority of older archive documents remain vendor-hosted without an independent badge.
Included because its broad catalog exposes repeatable public COA archive paths across many products.
A large, provider-verified COA archive: a public per-batch API surfaces a Freedom Diagnostics search code for nearly every product, and those codes resolve live in Freedom’s public index.
Simple Peptide publishes a public COA archive (a WordPress `coa-archive` REST API) that exposes a Freedom Diagnostics search code, purity, net content, and panels for each batch. In the latest audit, 139 of 183 certificate origins across 52 products independently resolved to a real Freedom Diagnostics report in the lab’s public index (a fake code correctly returns not-found), at ~99.5% average purity. The remaining ~44 are older attributable vendor documents kept without a provider badge.
This vendor is one of 113 names currently included in our manual curated research-vendor layer.
Simple Peptide is one of the clearest large-catalog examples of a vendor-hosted COA archive pattern. The strength is not outside-provider routing; it is the repeatability of public archive-style paths across many products.
- The current public pass reviewed 53 products and found 0 vendor COA links plus 0 vendor COA archive links.
- That makes Simple especially useful for readers comparing public-archive breadth rather than third-party verification depth.
- The main caveat is that this is still a vendor-controlled archive model, so it should be compared to vendors like Peptide Partners, Pure, and Kimera before it is compared to EZ’s outside-provider trail.
This is the strongest public transparency pattern on the site. The key signal is that readers can leave the vendor domain and inspect reports or verification pages on an outside provider domain without needing to log in.
- Treat the outside provider route as the strongest part of the evidence, not the vendor marketing copy around it.
- Look for repeated product-level behavior across the catalog, not just one showcase example.
- Do not overread it as proof that every current lot is covered or current unless the linked report trail itself supports that.
This vendor makes the most sense when you compare it to other vendors using a similar transparency model, rather than to every vendor on the board at once.
PB Curated Assessment is a PeptideBenchmark-authored rubric built from the trust and transparency review layer. It is separate from the source-derived benchmark score.
Simple Peptide is currently one of the strongest curated cases on the site because readers can inspect a repeatable public evidence trail without logging in.
Readers can leave the vendor marketing layer and inspect verification publicly.
This is the strongest public pattern because the verification step routes into an outside provider layer.
Current review touched 53 products and 190 document/link destinations.
1 named lab signal(s) and 1 certification category signal(s) are currently visible in the reviewed evidence.
Score 6.4 from finnrick average.
PB Curated Assessment: Strong. This is our own trust/transparency rubric and is kept separate from the PB score.
Under the formula retired on Aug 28, 2026 this vendor scores 7.56 — the live evidence-first score is 8.69 (+1.13). What changed and why: scoring methodology.
Observed from public domain records and the vendor's own site on Aug 27, 2026. Identity facts are shown for context and do not affect scores.
Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
14 of this vendor's 97 trace-comparable certificates come from lots also sold under Apex Peptides, Bench Grade Peptides, Blank, Nation Peptides.
These certificates contain a byte-identical instrument trace, meaning one analysis was reported for more than one label. Buying finished material from a contract manufacturer is ordinary and lawful, and this cannot establish which brand supplied which.How this is measured →

PB score is the number you should read first on this page. It starts with trust evidence, pricing coverage, and third-party review signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available. Reviewed transparency evidence contributes a bounded amount — shown as a trust lift for source-benchmarked vendors, and folded into the base score for PB-evidence vendors.
This vendor’s score is evidence-first: verifiable testing evidence forms the backbone, and outside review sources are a bounded adjustment that can warn far more than it can boost. The terms below sum to the displayed score (small rounding aside). Full formula on the scoring methodology page.
WHAT THIS PAGE IS

CURRENT LIMITS
- Not an original lab test or editorial review
- Source scales and methodologies differ across sites
- Depends on source site freshness and formatting
These are representative public examples from the vendor testing review queue. They show how product pages in the catalog expose public report or verification paths, but they should still be read as examples rather than proof for every current lot.
In other words: the relationship registry above captures the vendor-to-provider link itself, while the examples below show what that link looks like across real product pages.
METHODOLOGY
How to read this benchmark
This profile summarizes public benchmark data synced from Finnrick and, when available, Peptide Critic. Finnrick contributes a 10-point average from its vendor table, while Peptide Critic contributes a 5-star rating that we normalize to a 10-point scale before ranking consensus entries.
A high score can be directionally useful, but it is not a substitute for current COAs, identity testing, chain-of-custody details, or your own due diligence. We are intentionally separating source aggregation from first-party editorial claims.
Scores combine PB trust evidence with external signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available.
