Recently I have seen a few posts about this. People thinking that the supplement they purchased isn't actually what it claims to be. Not in the sense that the company that produced it didn't put the ingredients they say they did in it. In the sense that they purchased a specific brand supplement that they normally use and some unscrupulous person or company "faked" it by purchasing a bottle, labels and caps similar to the one of the original company. Does this actually happen and how often if so?. Also how would you know your product is fake?
