About These Terms
WheyProof (wheyproof.com) is an independent site that tracks the prices of sports supplements across brand and retailer websites. We don't sell products and we aren't a party to any purchase you make. By using this site you agree to these terms; if you don't agree, please don't use it. How we handle personal data is described in the Privacy Policy.
Prices and Product Information
Prices, stock status and product details are collected automatically from each store's own website several times a day. Between our checks a store can change a price, run out of stock or end a promotion, so what you see here may be out of date. The price and terms shown at the store's checkout always apply.
Our "real discount" signals compare the current price with the prices we have recorded ourselves. They describe our own records, not a promise about future prices, and a product we started tracking recently has less history behind its signal.
Nutrition Facts
Nutrition facts are copied from the brand's own Nutrition Facts panel, either the text on its product page or its label image, and published only after the calories check out against the protein, carbohydrate and fat on the same panel. A panel can still differ by flavor or package version, and brands change formulas. Always check the label on the product you buy, especially for allergens, which we don't list.
Affiliate Links
Some links to stores are affiliate links. If you buy something after following one, the store or an affiliate network may pay us a commission. It doesn't change the price you pay, and it doesn't decide which products we list or how deals are ranked: prices and discounts come from the same automatic checks for every store.
Not Medical Advice
Everything on this site, including guides and calculators, is general information and not medical, nutritional or fitness advice. Dietary supplements aren't intended to diagnose, treat, cure or prevent any disease, and statements about them haven't been evaluated by the Food and Drug Administration. Talk to a doctor or another qualified professional before starting a supplement, particularly if you are pregnant, nursing, under 18, taking medication or have a medical condition.
Acceptable Use
You may browse the site, share its pages and use its tools for personal purposes. Please don't copy the site's data in bulk, run automated scraping against it, try to get around its rate limits or access controls, or use it in a way that disrupts service for others. We record abuse attempts as described in the Privacy Policy and may block traffic that breaks these rules.
Other Sites and Trademarks
Store links take you to websites we don't control; their own terms, privacy policies and return policies apply there, and any purchase is between you and that store. Brand names, product names and logos belong to their owners and are used only to identify the products we track. Their appearance here doesn't mean the brand endorses WheyProof.
Disclaimers and Limitation of Liability
The site is provided "as is" and "as available". We work to keep the information accurate but don't guarantee that it is complete, current or error-free, or that the site will always be available. To the fullest extent the law allows, WheyProof isn't liable for losses that come from using the site or relying on its information, including a price that changed or a product that differs from its listing.
Changes and Contact
We may update these terms as the site changes; the date at the top of this page shows the latest version, and continuing to use the site after an update means you accept it. Questions about these terms: [email protected].
