Terms of use
The rules of the road, including how we’re paid and what this site is not.
Research use only. Products listed by these shops are sold for laboratory research use only. Nothing on this site is medical advice.
Affiliate disclosure
Some shops on PurityWatch are affiliate partners. If you click our links or use our codes and then buy, we earn a commission at no extra cost to you, and this can influence where those shops are placed. Scores of all other shops come from public information.
Scores and facts
Scores are editorial estimates based on each shop’s public information. Facts a shop doesn’t publish are shown as “not published”. Shops change their policies — check the shop’s own site before you order.
Coupons
Codes are provided by the shops and may change, run out or be withdrawn. We remove codes when they expire but can’t guarantee a shop will accept them. Each shop’s own terms apply to every order.
Reader reports
By filing a report you confirm it reflects your own experience. We may shorten reports or remove ones that break these rules, including any that contain medical claims or dosing information.
