Peptide Coupon Code Finder by Peptide Grading
Last updated: October 19, 2026What the Extension Does
When you visit a peptide vendor listed on Peptide Grading, the extension shows that vendor's Peptide Grading coupon code. You can copy the code, have it filled into the store's coupon box, or open the vendor's offer link.
It also shows the vendor's Peptide Grading rating and COA count, compares the price of the peptide you are viewing across vendors, and lets you search peptides and vendors listed on Peptide Grading.
On Google, Bing and DuckDuckGo search result pages, it shows a small coupon line above results that link to a store with a Peptide Grading coupon.
What We Collect
Nothing. The extension does not collect, store or send your browsing history, the pages you visit, what you buy, your name, email, payment details or any other personal information. It has no analytics or tracking.
To decide whether a page is a supported store, the extension compares the website's address with its vendor list inside your browser. That check never leaves your device.
On Google, Bing and DuckDuckGo search result pages, the extension reads the web addresses of the results shown on the page and compares them with the same vendor list, on your device, to decide where to show a coupon line. It does not read, store or send your search terms, and the result addresses never leave your device. You can turn this off in the extension's settings.
For price comparison, on supported vendor sites only, the extension reads the product page's title and main heading to recognise the peptide, for example, “BPC-157”, and matches it against the price list it already downloaded. This also happens only on your device; the page content is never sent anywhere.
Searches you type in the popup are matched against the same downloaded list and are not sent anywhere either.
Network Requests
The extension downloads the public list of vendors, coupon codes and peptide prices from peptidegrading.com about every hour. The request contains no information about you or your browsing.
When a store has no coupon, the popup lists other stores with Peptide Grading coupons and loads their logos from peptidegrading.com or Google's public favicon service. These image requests carry no information about you or the page you are on.
What Is Stored in Your Browser
The cached vendor, coupon and peptide price list.
Your settings: coupon notices, search result coupons, price comparison and auto-fill on or off, and stores where you chose “Don't show again”.
Stores where you closed the coupon card, so it stays hidden for 24 hours.
This data stays in Chrome storage on your device. Removing the extension deletes it.
Affiliate Links
Some coupon offers use an affiliate link. The extension only opens one when you click “Activate offer”, never on its own and never on cart or checkout pages.
Peptide Grading may earn a commission on purchases made through these links, at no extra cost to you.
Permissions
Read and change data on websites: Needed to recognise vendor stores, show or fill the coupon code and show the price comparison, and to show coupon lines on search result pages. On every other website, the extension stops immediately and reads nothing.
Storage: The cached vendor list and your settings.
Tabs: To show the coupon for the store in your current tab in the popup and toolbar badge.
Alarms: To refresh the vendor list in the background.
