Before you order
Every product sold by KUULPEPS.com is supplied strictly for laboratory research. It is not a medicine, supplement or food, and it is not for human or veterinary consumption, diagnostic or therapeutic use. By ordering you confirm you are a qualified purchaser using the material in a controlled research setting.
Each lot is analysed by reverse-phase HPLC for purity and by mass spectrometry for identity before release. The batch record — lot number, assay result, method and test date — is available on our quality page and ships with the order.
Orders leave our European facility within 24 hours on business days. Spain typically arrives in 1–2 working days and the rest of the EU in 2–5 working days, insulated for cold chain where required.
Tracked EU-wide shipping is a flat €19, and free on orders over €150. We ship within the European Union only.
