Description
PER4M PUMP is an innovative stim-free pre-workout built to deliver powerful muscle pumps, sharp focus and consistent performance - all without the caffeine crash. Ideal for serious gym-goers who want maximum results at any time of day, including evening training.
10g L-Citrulline – for enhanced blood flow and muscle fullness
3g Taurine – for hydration and performance
Neuro blend – to support focus and mind-muscle connection
Zero caffeine – perfect for stacking with stim-based pre-workouts
Includes Glycersize™ – for next-level hydration, volume and vascularity
Where most pump formulas suffer from clumping due to moisture-absorbing ingredients like Glycerol, PER4M PUMP takes a smarter approach. To keep the formula smooth and easy to use, Glycersize™ is provided as a separate formula included free with every tub. Add it alongside your PUMP serving to experience full-body hydration, increased endurance and muscles that look fuller and more vascular - without the mess of clumped powders.
Glycersize™ is a premium glycerol formula that helps hydate your muscles, keeping full and vascular during training. It boosts endurance and pump, and by including it as a separate scoop you get all the benefits without the clumps.
