No one can offer proof on the matter even though many have had various experiences, but chances are if it was charged in Mexico it was made in Mexico. I don't know why someone would buy more expensive products from somewhere else, import it to Mexico then sell it if they can buy it cheaper next door. But also, just because it was made in Mexico doesn't mean it isn't real either. Just test it as it is not an expensive product to make legitimately. Let us know your results. You can find fake garbage in the US and real stuff in Mexico. The location alone doesn't mean everything. Good luck and like I said let us know as we are always interested in learning more. But it sucks when you think you are buying one thing only to find out it is coming from somewhere else. Many Americans learned they could buy things from Cananda for example, but even though they call themselves Canadian pharmacies, it comes from an entirely different country. It is all part of the game we are all playing. The more we can learn the better and just consider yourself part of the experiment. Good luck.
