USN website suggests how they stand on contaminated supplements. It does happen and basically the teams they sponsor and individuals they endorse, the product comes out of a very specific factory. Im assuming tighter controls and QC. For example to manufacture a hydration drink uses a large variety of raw materials. More than likely from a variety of suppliers from all over the world. It seams quiet possable mistakes happen. How sure are you that you do actually get that 24g of protein or what the container suggests. I recon not very often. Wasnt it recently a pro got done for some steroid indication. They found it came from meat he had eaten. Its every where. Mistakes and contamination do happen. Let the investgation run its course.
