VMI Sports® Pre-Workout KXR® is THE superior breakthrough formula! KXR® is designed using the latest cutting-edge ingredient science to provide athletes, bodybuilders, fitness enthusiasts, and weekend warriors alike, with unmatched levels of sustained energy and endurance. Featuring our unique tri-blend of 3 unique sources of Caffeine including Infinergy®, our KXR® Preworkout has time released energy & NO CRASH! The KXR® formula is loaded with 3.2 g of beta-alanine & 1.5g Taurine to help significantly amplify muscle power and performance while training, and 300mg of Theobromine to support muscle pumps. KXR® is also infused with an additional 150 mg of elevATP®, a natural combination of ancient peat and apple polyphenols clinically shown to increase levels of endogenous ATP. This means more energy in the muscle cell, and therefore pushing more weight! For increased Focus & Cognition support, KXR® is enhanced with 500mg of VitaCholine® from Albion® as well as 300mg DMAE, and 3mg of Huperzine. DMAE and Huperzine are thought to work by increasing production of acetylcholine, a neurotransmitter that's crucial for helping nerve cells send signals. Last but not least, KXR® is reinforced with 1.5mg Rauwolfia Vomitoria Root Extract, a form of Yohimbe used to boost intensity and metabolic support. KXR® Pre-Workout can be easily stacked with Vasogen Pump Caps, Aminogex® BCAA/EAA, and ProtoLyte® 100% Whey Isolate Protein, for improved results.
