I did some very minimal Google research. sounds banned for humans in UK, Germany, and a few other places. I guess some label it not for human consumption like research chems. otherwise you can just buy it from the USA and hope customs doesn't take it
A lot of people don't realize that labeling things as not for human consumption doesn't make them any less illegal. In the eyes of the government, the compound is either legal or it isn't. For example, Viagra is a prescription drug - therefore, its a drug in the eyes of the law. Putting it in a liquid vial that says not for human consumption doesn't make it any less of a drug bc the compound itself is a drug. That's been a myth that research chem sites have told people for ages and people believe it but the truth is, if you don't have a research license to buy and sell it, its still illegal.
There have been dozens of research chemical companies busted over the years. Sometimes it makes the news and sometimes it doesn't (and it usually doesn't in the cases where they give the people plea deals to testify against other companies and suppliers). As long as there is money in it, there are always going to be people that are willing to take the chances.
In the UK/EU, I don't think the labeling it that way is as big of a thing. But there are a lot of things that are illegal there that some retailers still take a chance on selling in some cases. So in the case of our Kava product when we release it, it will be up to the retailers to determine the legality in their own individual markets and on whether to offer it or not.
