Privacy Overview

This site uses cookies and similar browser storage. Some are needed for the site to work: your cart, your login, the age confirmation and this cookie choice. Others are optional and load only if you accept them: visit statistics, page-usage analytics and the support chat, all listed under “Third party services”. You can change your choice at any time from the cookie settings link in the footer.

Strictly necessary

These keep the site working and cannot be switched off: your shopping cart, your login session, the age confirmation, and this cookie choice itself. They are set by this site only and are not used to track you elsewhere.

Third party services

These services are provided by other companies and are only loaded once you accept them. Nothing here is needed to browse the catalogue or place an order.

Google Analytics 4 (Google Ireland Ltd). Measures which pages and products are visited, so we can see what people look for. Sets cookies in your browser.

Contentsquare (Contentsquare SAS). Records how pages are used, such as clicks and scrolling, so we can see where the layout is unclear. Sets cookies in your browser.

Peptoid support chat (peptide.bot). Loads the chat widget in the corner of the page and answers questions about compounds, batch records and orders. Your messages are processed by that service to produce a reply.

Decline and the site works exactly the same, minus the chat widget and the visit statistics. You can change this at any time from the cookie settings link in the footer.
