Muscletech Shatter Black Onyx is designed to stimulate intense muscle pumps! Athletes looking to improve their muscular strength and endurance have come to the right place. The scientifically advanced formula is rich with hawthorn berry, a natural ingredient known to increase nitric oxide levels.
High nitric oxide levels are so important within workouts, because it supports oxygen flow within the bloodstream. The more oxygen within the blood flow, the less likely it is for athletes to cramp up during high-intensity workouts. High oxygen levels help athletes perform at their best for longer, creating unbelievably powerful pumps.
The best-in-class pre-workout formula also amplifies energy levels. The ultra-potent caffeine enhances mental focus and provides an intense burst of energy to get you through those tough training sessions. Our Extreme Neuro-Sensory Matrix combines caffeine, alpha-GPC, TeaCrine and alpinia, to produce heightened nitric oxide levels, ultimately prolonging workouts.
