Cookies and device storage

Last updated: 30 September 2026.

Essential device storage

The website stores your cart, selected market and privacy choice on your device. This is needed to keep those choices between pages and visits.

When you place an order, delivery and payment details are entered on our hosted checkout at checkout.definepeptides.com, operated by our payment provider TagadaPay, to complete the purchase.

Optional measurement

Optional website measurement runs only after you accept it. Rejecting non-essential storage does not prevent browsing, selecting products or using the cart.

Change or withdraw your choice

Use Cookie preferences in the footer at any time. A changed choice applies to future optional measurement. You can also clear stored site data through your browser controls; doing so may clear your cart and preferences.
