Google Analytics only runs if you click Accept on the cookie banner. It sets cookies and tells us things like your device type, browser, rough location (country or region), which pages you view and which vendor links you click. If you decline, or don't choose, it isn't loaded at all.
Advertising features and Google Signals are switched off, and we don't run ads. Before a page address is sent to Google, we strip it back to the page plus any search, category or vendor filter, and drop a search that looks like an email address or phone number.
Google explains how it uses this data here: How Google uses information from sites that use its services.
We also use Cloudflare Web Analytics, which counts page views and measures how quickly pages load. It doesn't use cookies or store anything in your browser, and it runs whether or not you accept Google Analytics.
Every page also loads its fonts from Google Fonts, so your browser contacts Google for those whether or not you accept analytics.
You can decline, or change your mind any time with “Cookie settings” at the bottom of each page. Your choice is remembered in this browser. If you turn analytics off after accepting, we stop Google Analytics and delete its cookies for this site.
If you sign up for alerts, we store your email address, the peptides you've saved, which emails you want (deals and price alerts), when you signed up and last updated, where on the site you signed up, and a private code that makes your unsubscribe link work. Your browser also remembers your email and saved peptides on your device.
Every email we send includes an unsubscribe link. Unsubscribing stops the emails straight away; we keep a note that you unsubscribed.
We don't sell your address, and we don't share it with vendors or advertisers.
The review form stores the vendor, your rating, the name you enter, your review, the peptide you ordered (if you add it) and the date. Every review is checked before it appears. Approved reviews show the name, the peptide and the date, so please don't include anything you'd rather keep private.
When you click through to a vendor, we add one to a counter for that vendor and peptide. The totals drive the “popular” badges and the most-clicked sort. The counter doesn't record who clicked.
We use IP addresses only to limit spam and abuse. The sign-up and review forms count submissions per IP address for up to an hour after the last submission, then the count expires.
Our host, Cloudflare, handles every request to this site and processes IP addresses to deliver pages and block attacks.
Some vendor links are affiliate links, so we may earn a commission if you buy, at no extra cost to you. See the disclosures on the price comparison page. Once you're on a vendor's site, their own privacy policy applies.
