Description
Check Gold Standard Analytics certificates (COAs) on any shop page. Fakes, retractions and edited PDFs stand out. Gold Standard Certificate Checker verifies the certificates of analysis (COAs) that shops post, in one click, on the page you are already reading. Peptides, research compounds, kratom, CBD and supplements are sold "with a COA" all the time. Some of those certificates are real. Others were issued for a different lot, edited in a PDF editor, copied from another brand, or quietly withdrawn by the laboratory. This extension checks each one against Gold Standard Analytics' own records and tells you which is which. HOW IT WORKS Open a product page and click the Gold Standard button. The extension reads the page, finds every Gold Standard certificate number (GSA-YYYY-NNNNNN) and every certificate link, and marks each one: ✓ Verified · Pass — a genuine certificate, and every published result was within specification ✕ Verified · Fail — a genuine certificate on which at least one result failed. The certificate is real; the product failed a test ! Retracted — Gold Standard withdrew this certificate. Do not rely on it ? Not found — no public certificate has that number. It may be private, mistyped, or not genuine Click a mark to see the compound, lot, client of record, issue date and methods, and to open the certificate itself. AN EDITED PDF CANNOT HIDE A published certificate never changes. The extension compares a seller's PDF byte for byte with the file Gold Standard issued and tells you whether it is the same file or a different one. You can also drop any certificate PDF onto the extension's Verify page, or paste a link to it. CERTIFICATES POSTED AS PICTURES Many shops post a screenshot of a certificate instead of a link. Right-click the image: the extension reads the QR code printed on every Gold Standard certificate and checks it. WHAT YOU ACTUALLY PAY PER MILLIGRAM The extension shows the price per labelled milligram, and per measured milligram when the certificate states the amount in each vial, so two "10 mg" vials at different prices can be compared honestly. It also shows the tested lot's net peptide content. THE QUESTIONS A PRODUCT PAGE DOES NOT ANSWER • Was this certificate issued to this seller? The extension compares the client of record with the shop and tells you when they differ. • Which laboratory is this from? If a page names another lab, the extension says so and links to that lab's own verification page. It never claims to verify another lab's certificate. • Is there a cheaper way to get this tested? It opens a testing order pre-filled with the product's compound, and shows any open group test for it. ALERTS Follow a certificate and you will hear if it is ever retracted or withdrawn. Follow a compound or a brand and you will hear when a new public certificate is issued. The extension checks every few hours in the background. FOR SELLERS Scan your own Shopify or WooCommerce store and see, product by product, which listings carry a certificate, which point at a retracted or non-public one, and which have none at all. Export the table as CSV, and start one pre-filled testing order per category for the rest. PRIVATE BY DESIGN The extension sends goldstandardanalytics.com only the certificate numbers it checks (and a private certificate's own key, when a link you check carries one). It never sends the pages you visit or your browsing history. There is no account, no analytics, no advertising and no third-party code. Nothing is read until you click, unless you switch on automatic checking yourself. Your history and follows stay in your browser.
