This video is Dr. Group. He's the guy who developed it. When you buy Oxypowder , they have a huge section on his medical qualifications. They go on to say that oxypowder is FDA approved, it's vegetarian, organic, and so on. There are even mentioned of some specific celebrities and body builders using it. Honestly? I haven't heard one legitimate complaint about the product. At the very least? You can try it for 30 days or so, and if you don't like it, they give a money back guarantee. They also seem focused on educating people which I think is a big selling point. It's not just about selling the product, but about giving people a wealth of health information as well.
