K-XR is a pre-workout supplement from VMI Sports. It is designed to give users “relentless” stamina and energy, as well as “tunnel vision focus” and more satisfying muscle pumps.
The pre-workout contains a total of 400mg of caffeine in three forms: Caffeine citrate, caffeine anhydrous and di-caffeine malate. Along with hordenine HCI, these ingredients are part of a “Maximum Energy Blend” which VMI Sports includes to give users a mix of slow-acting and fast-acting energy.
K-XR also contains theobromine for muscle pumps, beta-alanine for endurance and taurine for hydration. Choline bitartrate and huperzine A are also included to help users increase focus.
