I don't know how draconian the laws are? I mean, some places (like the good old USA) don't want medications shipped in or brought in, but if intercepted and it's a 3 month supply or less, you are just going to get a letter in the mail stating your medication package has been opened and is being sent back. Try importing a controlled substance though, that's an entirely different story.
I think you'd be able to find SOMEPLACE that will sell and ship it to you, but it may not be so reputable, and also guarantees on the product arriving unscathed may not be offered, e.g. if your juice gets intercepted then you are out of luck. With that said, I'd really check out the laws and penalties involved, first, and THOROUGHLY, as I for certain do NOT want to advise you to do anything illegal. At all.
