That's very simple,
here in Canada, everything that's realy work is illegal.
The primary reason is that all suplements are made outside the country, so the governement makes them illegal cause all the factory are outside, so they make no money.
another reason is beacuse they lose money : for exemple, the fatburner : the american version works well but all the ingredients are illegals. So if all the fat person take fatburners and become slim, they lose money in cares, all bullshit sell in drugstore, and all stuff who doesn't work.
so that'S why everything is illegal.
Buy in USA, it'S a lot better, for the same price
