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 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. What Animal M-STAK(R) Is Hard gainer. You're a hard worker and you give it everything you got 24/7 but the gains are hard to come by. As a classic hard gainer, you train big and you eat big, but you have little time to show for it. Animal M-Stak is a non-steroidal product geared specifically for you. Through its unique set of properties, most notably "nutrient-partitioning", Animal M-Stak helps you maximize your lean gains with greater efficiency and effectiveness. Work hard. Don't gain hard.

Suggested use

Take a pack every day for 21 straight days. On training days, take it 30-45 minutes before lifting. On off days, take it between meals. Cycle Animal M-Stak for best results-three weeks on, one week off. Repeat as needed. The entire Energy Complex (stims) is contained in the single red capsule. Remove it as you see fit.
