The Ultimate Energy & Performance Stack. Focus & intensity, quick and sustained energy, endurance. Who we are, in 1983, Animal was founded with the birth of Animal Pak, the venerable training “pack” that started it all. Born from the needs and desires of pro bodybuilders, Animal has grown prodigiously over the decades. Today, Animal has stood the test of time and been proven in the trenches day in and day out. The name stands for trust, integrity and a no nonsense approach to the game.
