Being that i live her ein mexico, i get to see alot os internaional gear imported in not to mention real vet gear produced here! But with that being said as soon as you see a influx of real AS the scum of mexico catch on super quick and the fakes pop up like wild fire! to the point where there is a vet store right off Revolution(main strip in tijuna) thta has been selling fakes for 10 years...they have never ordered from any legit lab! Also the largest Farmacia on the strip has been delaing in fake human meds as well as vet gear for over 15 years and are still in business with everyone knowing this!!! These people prey on the newbies, tourists and people who follow name recognition(i bought from these guys about 10-15 years back and thought that i couldnt go wrong with Organon....but the stuff looked super real and was really fake!!!) AS some of the earlier posts suggest, if you know the person that is HELPING you...(still do you research) it comes down to haing to trust the person that helps you!
