It's "for research purposes only". I don't know the specifics of the legality of the product but there are numerous web sites that sell it. Although I'm not sure of the rules so I'll just keep my mouth shut for now.

Here's a clip from a site which sells it.

The materials for sale are intended for laboratory and manufacturing use only. They are NOT for use as food additives, drugs, cosmetic, household chemicals, or other inappropriate applications.

If I am not mistaken they are considered non-controlled substances. Customs usually let these meds go throw anyway.

arimidex is a presciption drug which you can legally import from other countries as long and it isn't over a 3 month supply. liquidex is a liquid form of the same drug but sold for research purposes.
