Just put it in apple juice or alcohol, you'll claim it has an effect whrn administred without being illegal. Adding vitamin C as a cut can be good also, trace it back to myprotein ^^And legality varied between countries and as time presses on. What is legal today might be declared illegal tomorrow.
The best option for determining what drugs are and are not legal is by knowing the law in your country. In some jurisdictions even if you have a legal chemical, if you sell or give it to someone just claiming it is a narcotic/drug or has an effect like one (it could be sugar for all the law cares) it is considered a crime just like selling a drug.
