Face it, you're a classic "hardgainer".

This means you got fewer corners to cut.

You gotta bust your ass, gotta work twice as hard and eat twice as much just to gain a hard earned pound of muscle. For you, the all new Animal M-Stak has been formulated.

Animal M-Stak is the perfect hardgainer's pack.

Thanks to its significantly improved "nutrient-partitiong" effects, its ability to promote anabolism via protein synthesis and nitrogen retention, and enhanced anti-catabolic factors, the new M-Stak can turn "hardgainers" into "hard" gainers.
