If you’re training or dieting hard for a contest, the first thing that happens when you don’t take the Animal Pak is that nutritional gaps begin to form. Why should you care? Because over time, these deficiencies continue to grow. Eventually, your body will stop functioning at its optimum level. In other words, you hit the wall, your development reaches a plateau. In fact, even if only one key nutrient is missing from your diet, your body could shut down the anabolic drive needed to build muscle so that it can support more critical metabolic processes. When this happens, you stop growing.
