TBJP Pumpage 400g, Stim-Free Pump Pre-Workout

TBJP Pumpage is a stimulant-free pump pre-workout built around a multi-pathway NO and hyperhydration complex. Each 10g serving delivers L-citrulline 3000mg, GlycerSize (65% glycerol) 2500mg, PeakO2 1000mg, betaine 1000mg, taurine 1000mg and S7 50mg. The 400g tub provides 40 servings.

L-citrulline at 3000mg drives vasodilation via the arginine-nitric oxide pathway. GlycerSize at 2500mg (65% glycerol) works by hyperhydration - drawing additional water into muscle tissue for greater cellular volume and that sustained tight pump during high-rep training. PeakO2 at 1000mg is a patented adaptogenic mushroom complex studied for VO2 max and time-to-exhaustion. Betaine at 1000mg supports cell osmolyte function and power output. Taurine at 1000mg maintains cellular fluid balance. S7 at 50mg is a plant extract blend that elevates nitric oxide production through a separate mechanism to citrulline.

What separates Pumpage from a basic citrulline powder is the GlycerSize and PeakO2 additions. Citrulline drives NO-based vasodilation. GlycerSize drives mechanical hyperhydration - a physically different pump mechanism that stacks rather than duplicates. PeakO2 targets the aerobic side of performance, making Pumpage relevant to high-volume or conditioning-heavy training, not just standard strength sessions.

Pumpage suits lifters who train in the evening, those who have hit their daily caffeine ceiling, and anyone who wants the full pump experience without stimulants. It stacks cleanly on top of any stimulant pre-workout for heavy sessions. It is not the right choice for trainees who rely on a stimulant kick to start training. No common allergens declared.

Frequently Asked Questions

What is a pump pre-workout?

A pump pre-workout is a stim-free formula built around blood-flow ingredients like L-citrulline and glycerol. TBJP Pumpage gives you the training experience of a high-volume pre-workout without the caffeine - useful when you train late, when you want to stack on top of a stim pre, or when you are doing a stim-free training block.

Can I stack Pumpage with my stim pre-workout?

Yes - TBJP Pumpage stacks cleanly with your usual stimulant pre-workout. Mix one scoop of Pumpage with one scoop of your stim pre-workout in 400–500ml of cold water and drink 20–30 minutes before training. The extra citrulline drives blood flow without adding caffeine on top.

When should I take Pumpage for the best pump?

Take TBJP Pumpage 20–30 minutes before training. Mix one scoop with 300–400ml of cold water - the extra volume amplifies the citrulline effect. Use on training days. Particularly useful for late-evening sessions where you want pump and performance without disturbing sleep.
