iOX what can I say about this product?!. Being a competitve bodybuilder, I have a very demanding training regiment, and when I was introduced to this product, it was awesome!! My recovery between sets and endurance during a set increased substantially!! I even used it during my prejudging posing session and what a difference it made. Love this product!!!
As a mma competitor and all around athlete, I need excellent cardiovascular conditioning. My best description of the product would be maximum oxygen. It feels like one breath provides the energy of two. Its a great product with no stimulants if you don't want the jitters.
