Pre-Workout Concentrate & Oxygen Potentiator. Glycocarn for intense pumps, strength and endurance 3,7-dimethylpurine-2,6-dione for breathing capacity. Rev-Pea for sustained effect CNS stimulation Quercetin for promoting muscle mitochondria. In the era of concentrated pre-workouts, the race is on to create even stronger products with no emphasis on long term increases in: performance, muscle growth or preventing devastating 'crashes' that can ruin your workouts. D Stunner features an advanced stimulytic blend of with Rev-Pea which results in a no crash, sustained energy experience.

The combination of 3,7-dimethylpurine-2,6-dione and N-Methyltyramine HCL presents a new age advancement in the pre-workout category as it aids in improving breathing capacity. This advancement combined with Quercetin (Quercetin may increase aerobic performance through muscle mitochondria) may lead to the maintenance of oxygen uptake.
