Zombie Labs - King Of Pumpz

King of Pumpz by Zombie Labs is a high-powered stim-free pre-workout designed for lifters chasing maximum muscle pumps, performance and focus without caffeine. Built around clinical pump ingredients and performance compounds, this formula is engineered to drive serious blood flow, muscular fullness and training intensity without jitters or crashes.

Unlike stimulant-heavy pre-workouts, King of Pumpz focuses on nitric-oxide production, hydration and performance support so you can train hard at any time of day. It’s ideal for late-night sessions, caffeine-sensitive athletes or stacking with stimulant pre-workouts to customise your training setup.

Key Benefits

• 100% stimulant-free formula with zero caffeine for clean performance
• 10 g citrulline per serving to support nitric oxide production and muscle pumps
• Triple creatine matrix (5 g) to support strength, power output and muscle fullness
• 3.8 g beta-alanine to help support endurance and delay fatigue during high-volume training
• Nootropic ingredients to support focus and mind-muscle connection

How to Use
Mix 1–2 scoops with water and consume 20–30 minutes before training.
Start with a smaller serving to assess tolerance.

Who It’s For
Ideal for athletes and gym-goers who want maximum pumps, endurance and focus without stimulants, or for those stacking it alongside a caffeinated pre-workout.
