VMI KXR® Original Pre-Workout – Intense Energy, Focus & Performance Amplification

VMI KXR® is a high-stim, performance-driven pre-workout formulated for athletes who demand maximum energy, heightened focus, and endurance support during intense training sessions.

Featuring a time-released caffeine tri-blend, performance-enhancing amino acids, and advanced cognitive compounds, K-XR delivers powerful stimulation without the sudden crash commonly associated with high-caffeine formulas.


High-Energy Formula with Time-Released Caffeine

At the core of K-XR is a carefully balanced caffeine blend yielding 400 mg of total caffeine, sourced from caffeine citrate, caffeine anhydrous, and Infinergy® (di-caffeine malate).

This multi-source system provides both fast-acting stimulation and sustained energy release, helping maintain intensity and alertness throughout demanding workouts.

  • 400 mg total caffeine: High-stim energy output
  • Infinergy® di-caffeine malate: Slower release, smoother experience
  • No sudden crash: Designed for extended training sessions

Performance & Endurance Support Matrix

K-XR includes a targeted performance matrix designed to support muscular endurance, power output, and training capacity.

  • Beta-Alanine (3.2 g): Supports muscular endurance and fatigue resistance
  • Taurine (1.5 g): Assists cellular hydration and muscle performance
  • Theobromine (300 mg): Smooth stimulant support and vasodilation
  • elevATP® (150 mg): Supports cellular ATP production and power output

Advanced Focus & Cognitive Enhancement

To complement its stimulant profile, K-XR includes a dedicated cognition and focus matrix designed to enhance mental clarity, reaction time, and mind-muscle connection.

  • VitaCholine® (500 mg): Supports acetylcholine production and focus
  • DMAE (300 mg): Cognitive support and mental sharpness
  • Huperzine A (1% – 3 mg): Helps sustain neurotransmitter activity

Intensity & Metabolic Drive

K-XR is reinforced with Rauwolfia vomitoria root extract, a botanical compound traditionally used to support training intensity, drive, and metabolic stimulation.

This addition makes K-XR best suited for experienced stimulant users seeking elevated training aggression and focus.
