GDA STACK™ - Natural Muscle Builder WHY NutriJa® GDA STACK™ combines 12 innovative Glucose Disposal Agent (GDA) ingredients which aims to improve muscle insulin sensitivity and optimise nutrient handling leading to more amino acids and glycogen being directed to muscle cells. By better harnessing the power of insulin you not only effect greater gains in muscle recovery and muscle fullness but also a reduction in bodyfat. As such, GDA STACK™ is a supplement which stands out as one of a rare type which is equally effective regardless of if your primary goal is to build muscle and strength or if it is to boost fat loss while retaining the maximum amount of muscle. WHEN GDA STACK™ can be used during both bulking and cutting phases since regardless of your current goal it will help support gains in lean body mass and fat loss. Of course, if you are using it when dieting you would see faster gains in fat loss compared to muscle gains but its mechanism of action is uniquely capable of supporting your physique goals at any time and for this reason it is best used on an ongoing basis to gradually shift your body over time to a leaner, more muscular one. WHO GDA STACK™ is suitable for both men and women looking for a product that improve their physique and does so naturally without any negative side effects
