Resources

We sell the equipment and nothing else. This page is for the question that follows: where people get the compounds themselves, which is not something we supply, advise on or have any part in.

Some links below are affiliate links, meaning we are paid a commission if you buy through them at no extra cost to you. Read the full disclosure.

Laboratories

These are laboratories other people use. We have no commercial control over any of them beyond an affiliate arrangement, we do not verify what they send, and we make no claim about the quality, legality or suitability of anything they sell. Do your own checking.

A word on ordering from abroad. Every laboratory above ships from the United States. A parcel entering the UK goes through customs, which means it can be delayed, charged duty, or held. That is between you, the sender and Border Force. It has nothing to do with your order from us, which ships from within the UK and arrives in a day or two.
