Before training sessions, athletes can blend a 40-calorie scoop of MusclePharm Assault preworkout supplement into a glass of water to help fuel their workouts and build lean muscle mass. Each 2-pound jar contains 32 servings packed with creatine HCL to help fortify muscle fibers, ginseng extract to help increase energy, and lactic-acid buffers to help reduce muscle fatigue while pulling trains with your teeth. The powder is also free from 1,3-dimethylamylamine stimulants and is certified from Informed-Choice as free of banned substances.
