SHOTGUN 5X is the first VPX® muscle building supplement to use a superior synergistic blend of effective compounds combined with a cutting-edge delivery system that promotes mind blowing, skin bursting effects, while additionally supporting recovery and protein synthesis.* Compounds such as Creatine, Beta-Alanine, and Branch Chain Amino Acids are each combined with Ethyl Ester technology to promote maximum absorption and uptake!* The Ethyl Ester Compounds used in SHOTGUN 5X help these potent muscle building ingredients enter the bloodstream nearly 100% intact, as opposed to the same ingredients without Ethyl Ester technology that might only be absorbed at 15% to 40%.* This highly advanced Ethyl Ester technology shuttles these SHOTGUN 5X compounds across the muscle cell G47membrane where they can help promote muscle growth!* VPX highly recommends stacking pre-workout SHOTGUN 5X with post-workout SYNTHESIZE.
