Universal Nutrition 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. 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 safed 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. Directions use: Take one pak every day for 21 consecutive days. On training days, take pak 45 minutes prior to exercise. On non-training days, take pak in the morning or early afternoon. Cycle product for maxium results: three weeks on and one week off.
