REFERRAL OFFER
20% off with disclosed code
Standing PeptideBenchmark code renamed from peptides to benchmark. Prior checkout verification on 2026-07-17 showed 20% off ($79.60 on a $398 subtotal); the cart success notice does not update the displayed total — checkout shows the actual discount.
PeptideBenchmark has a disclosed affiliate relationship with American Peptide Research. This does not change benchmark scores or trust ratings — it only affects outbound links and pricing-board discount modeling where applicable.
Readers who want a straightforward storefront whose COAs come from a recognized third-party lab (Janoshik) at consistently high purity, rather than generic in-house testing claims.
The Janoshik reports omit the on-report key needed for one-click verification, and cover HPLC purity + identity + net content only — no endotoxin, sterility, or heavy-metals panels. Treat them as named-lab evidence rather than a live verification portal.
Included because APR pairs a clean public WooCommerce catalog with a per-product COA image from a named third-party lab (Janoshik Analytical), which is materially more than generic purity language even though the reports stop short of one-click verification.
An openly browsable simple-product catalog where the product-gallery COA images are Janoshik Analytical TEST REPORTs — reading them shows ~99.5% average HPLC purity with identity and net-content quantitation, each stamped with a Janoshik task number.
Every product-gallery COA is a Janoshik Analytical TEST REPORT (~99.5% average purity across 26 products, with a Janoshik task number). Janoshik is a reputable third-party lab, but these reports print only the task number, not the on-report unique key, so they can’t be deep-verified two-factor at verify.janoshik.com — this is strong named-lab documentation, not one-click provider verification.
This vendor is one of 113 names currently included in our manual curated research-vendor layer.
This is a meaningful public transparency pattern, but the documents are still mostly hosted on the vendor side. That makes it stronger than generic claims and weaker than provider-controlled verification.
- Reward the fact that readers can inspect real files without logging in.
- Pay attention to whether the archive is broad, multi-category, or repeated across many products.
- Keep in mind that vendor-hosted files are different from a live third-party verification portal.
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.
American Peptide Research has enough public trust structure to be useful in the curated set, even if it is not one of the clearest verification leaders yet.
Readers can inspect real public documents, even if the vendor still hosts most of the archive.
The trust layer is structured and inspectable, but still mostly vendor-controlled.
Current review touched 54 products and 26 document/link destinations.
1 named lab signal(s) and 1 certification category signal(s) are currently visible in the reviewed evidence.
Score 4.3 from pb evidence score.
PB Curated Assessment: Promising. 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 4.45 — the live evidence-first score is 6.35 (+1.90). 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.

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

- No Finnrick score currently linked

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.
