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. More alarming is the fact that championship-caliber bodybuilders, even when supplementing with a regular multivitamin, were still experiencing significant nutritional deficiencies. A basic multivitamin supplement won't be enough. Competitive bodybuilders know that a superior multivitamin is the first line of defense. This fact is confirmed by studies which have revealed that 100% of Olympic weightlifters and over 90% of competitive male and female bodybuilders use a vitamin/mineral supplement like Animal Pak. These nutritional gaps not only affect your performance and size, but they begin to impact the way your other supplements work. For many of today's supplements to work efficiently, your body needs to be running on all cylinders. Nutritional gaps mean that your supplements may be rendered ineffective. For example, many supplements (e.g., prohormones) rely on enzymes and other substances in your body to "activate" them. Poor nutrition means poor conversion and activation of expensive supplements. Animal Pak is your insurance policy to prevent this from happening.
