Face it, you're a classic 'hard gainer'. This means you got fewer corners to cut. You gotta bust your hard work, 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 hard gainer's pack. Thanks to its significantly improved 'nutrient-partition' effects, its ability to promote anabolism via protein synthesis and nitrogen retention, and enhanced anti-catabolic factors, the new M-Stak can turn 'hard gainers' into 'hard' gainers. Now with new and even more powerful, Natural Flavone/Sterone Complex (including new Turkesterone), Anti-Catabolic Amino Complex (rich in leucine), Anabolic Adaptogen Complex (with safe musli and rosavins), Insulin Potentiating Complex (including colosolic acid and 4-hydroxyisoleucine among others), Energy Complex (as with Animal Pump, all the stims are in one red capsule for convenience and flexibility) and a new M-Factor Complex (with dihyroxybergmottin), the all-new Animal M-Stak is gonna blow the roof off the proven original.
