Going back to the original question, can you order it off of amazon.com (not co.uk)?

I assumed that Amazon would be smart enough to restrict orders to countries where the products are illegal or restricted, but I'm unsure whether independent sellers associated with amazon have the same restriction. In any case I bought some from another UK-based site. It was only like 20 quid for half a year's worth of pills so I don't consider it much of a loss if they don't arrive or are just sugar pills (which gwern points out is unlikely).
