Because MADNESS ALL-IN is an “All-In-1” pre-workout, it contains many of the benefits of other products within a single supplement. However, we highly recommend stacking ALL-IN with complementary products that can provide synergistic effects. Stacking with MUTANT GEAAR provides critical EAAs (essential amino acids) and added arginine (which helps support increased nitric oxide production and nutrient shuttling) enhancing the overall muscle building and performance support mechanism. Stacking MADNESS ALL-IN with proteins like ISOSURGE ensures a surplus of imperative BCAAs (branched chain amino acids), supports function/recovery via helpful electrolytes, and helps drive the performance and brute strength needed to lift heavier – allowing for maximum utilization of the macronutrients provided by MUTANT proteins.
