i would like to test some Biotest products but they aren't sold in Italy. i can buy them from UK but at really expansive fee.
for Italy it is quite simple...
the only remark is total weight. it is better to stay under 3.5kg
What is legal in US is legal in Italy (the only difference were the prohormones, but by now they are out also in US...)
ask at the custom office.
however fot Italy i can help you a bit (i usually buy from US)
yes you can. but you can also use egold or something like that.
as far as i know you have to know only US laws. you are not responsable of foreign law issue.
you can't sell items illegal in US or that can't be exported (but usually that are restrictions applied to know-how or technology...)
