Zombie Labs King of Pumpz

King of Pumpz by Zombie Labs is a powerful stim-free pump formula designed to deliver extreme muscle pumps, improved blood flow, and enhanced training performance without caffeine. Built for lifters who want intense pumps and focus without stimulants, this formula combines high-dose nitric oxide boosters, performance ingredients and advanced nootropics to support strength, endurance and mind-muscle connection throughout demanding workouts.

Featuring a massive dose of citrulline alongside agmatine, pine bark extract and pump-support compounds, King of Pumpz helps drive blood deep into working muscles to create fuller pumps and improved vascularity during training. The addition of creatine, beta-alanine and nootropic ingredients further supports performance, focus and workout intensity, making it suitable for stacking with other pre-workouts or using on its own for stimulant-free sessions.
