I once ordered 60 completely fake 2mg alprazolam bars from an
IOP that I think is based out of the Philippines. This
IOP is actually listed in these forums and has several positive reviews, much to my surprise. They were the GG 249 bars, which after doing some research, I discovered are quite often counterfeited. They arrived not in blister packs, but sealed in two thin sheets of plastic.
You can determine if these particular GG 249 bars are fake by measuring them. They are just a couple of millimeters off of the genuine meds. Thisinfo is readily available just by entering a quick google search. Another good way to test their legitimacy is by taste. Real alprazolam is extremely bitter, these bars in question were pure chalk, and had absolutely no anxiolytic properties (i have very little tolerance to benzo's).
