A few years ago I wrote an article about protein spiking. Since then many of these supplement companies that have been sued seem to have stopped using the protein spiking ingredients taurine, glycine, and creatine. However the other day I was in my local Aldi and found this. (see pictures)
You have to be careful anytime you buy protein powder. The supplement industry is filled with scum and they will bite you when you are not looking.
