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.

Watch-out

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 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.

Promising curated case

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.

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.
