This website uses cookies so that we can provide you with the best user experience possible. Cookie information is stored in your browser and performs functions such as recognising you when you return to our website and helping our team to understand which sections of the website you find most interesting and useful.

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.

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.
