VERIFICATION

Check the certificate before you buy.

Each vial is labelled with a lot number. Enter that number in the COA library and the certificate for that exact batch is returned — testing laboratory, method, HPLC purity figure and date of analysis. Lots still at the laboratory are listed as pending rather than left out. Certificates are published whether or not you have ordered.

COMMON QUESTIONS

Questions before you buy.

The ones that decide it, answered plainly. The rest are on the Learn pages.

Every product on this site is supplied as a laboratory material for in-vitro study. It is not a medicine, not a dietary supplement, and is not for human or veterinary use, ingestion or administration of any kind. We describe what a compound is — sequence, class, presentation, purity, lot — and never what it does in any organism. If you are looking for guidance on use, we cannot help you and neither can any legitimate supplier.

By the lot number. It is printed on the vial label and appears on the certificate; if the two do not match, the certificate describes different material. Enter the number in the COA library and the certificate for that exact batch is returned. Capitals, spacing and punctuation do not matter.

Tracked dispatch from Bulgaria, in discreet outer packaging with no product markings, within one working day of payment clearing. Delivery costs and estimated dates are shown in full before you pay — never added at the final step.

Yes. Under Irish and EU distance-selling law you have 14 days from the day you receive the goods to cancel, without giving a reason, and you must tell us in writing within that period. We refund within 14 days of being told, by the method you paid with. Vials that have been unsealed cannot be accepted back on hygiene grounds — that exception is set out in full in the Terms of Sale.

No. Guest checkout is available and always will be. An account is useful if you want order history or saved addresses, but nothing requires one.

Send us a photograph of the label. If the lot number is not one of ours we will tell you so plainly. We publish certificates whether or not you have ordered, precisely so that the number can be checked before money changes hands.
