We formulated Transparent Labs Muscle Builder with scientifically backed ingredients in clinical doses. This combination of ingredients have been shown in multiple human studies to increase muscle hypertrophy, ATP production, blood flow, oxygen uptake, and endurance in as little as one week. By promoting greater muscle anabolism, improving recovery from exercise, and enhancing skeletal muscle metabolism, PeakO2™ and ElevATP® create a revolutionary synergy that can help athletes, gym-goers, and bodybuilders achieve peak performance, day in and day out. Meanwhile, Epicatechin has potent antioxidant properties and is suggested to improve fat-burning and muscle-building processes. Best of all, Transparent Labs Muscle Builder is naturally flavored, sweetened with stevia, and contains absolutely no artificial food coloring, fillers, GMOs, or allergens.
