SLAUGHTER X is the masterpiece to your perfect workout regimen. Clinically formulated to provide elite lifters with long-lasting focus, vascularity, and power under the bar. Experienced athletes know that SLAUGHTER X provides:

  • Surges of Vascularity 
  • Sharpened Focus
  • Explosive power to build strength
  • Long-lasting endurance


SLAUGHTER X is formulated for the animals in the gym. Athletes who want to push through fatigue, excuses, and barriers can trust this intense, high-Stimulant pre-workout to provide results. That said, we need to make something very clear ‒  SLAUGHTER X is not designed for newcomers. Those who have not trained with a high-stimulant, high-vascularity pre-workout supplement should start with RESURRECTION. We’ve carefully designed SLAUGHTER X pre-workout for a spectrum of experiences providing elite athletes a training advantage. Here’s what you can expect: 

Surges of Vascularity 

One scoop of SLAUGHTER X provides a potent, 6000mg dose of L-Citrulline Malate which will begin to relax blood vessels, boosting nitric oxide production allowing more blood to pass through your body. This surge in vascularity helps to promote strength, longer pumps, and reduced post-workout fatigue ‒ enabling you to train harder and recover faster for your next workout. 

Sharpened Focus

All great bodybuilders and strength athletes will tell you that what you do in the weight room is an art ‒ an art that requires focus, dedication, and ultimate precision. 500mg of Choline Bitartrate and 750mg of L-Tyrosine acts as a nootropic, working as a cognitive enhancement supplement to boost mood, focus, and dopamine production within minutes of ingestion. Expect surgeon-level precision matched with powerlifter-level dynamic strength.  

Explosive Power to Build Strength

At the end of the day, a great pre-workout shouldn’t just be a focus enhancer and a vascularity booster ‒ all athletes need power. SLAUGHTER X delivers a smooth, upward curve of energy and power throughout the workout. As 400mg of Caffeine Anhydrous gets you ready for a powerful attempt at a personal best, 40mg of Synephrine HCL starts to oxidize fat, promoting longer periods of power and strength. This isn’t your average pre-workout that pumps you up and leaves you hanging mid-set. 

Long-lasting Endurance

We didn’t forget about those of you who train hypertrophy or focus on higher rep ranges. Long-lasting endurance is achieved through 2000mg of Beta Alanine. Acting as a lactic acid buffering agent, Beta Alanine limits your physiological response to fatigue and lactic acid buildup ‒ allowing you to train harder, for longer. Imagine working out without the mid-set fatigue. Sets that were originally 6-8 reps with fatigue at 5, can now be 8-12 without breaking form. 

SLAUGHTER X, the masterpiece to your perfect workout regime.
