I have had it a couple times while traveling in Europe and I still have an upopened bottle of it that I got on my last trip to Europe about five years ago. You can not get it anywhere in North American as far as I know. The stuff they sell here isn't the same. It can be nasty stuff if you are unprepared, but very interesting...
If you want more info, pm me as its not really a discussion to have on a public forum.
