American Peptide Research

6.35 PB score / 10 Band D

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.

Best for

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.

Publicly inspectable

Product-gallery COA images from a named third-party lab

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.

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.
