CBUM Thupper Pump - Blue Raspberry
$99.95
Unit price perWhen caffeine is not the goal but a big pump is, the CBUM Thuper Pump delivers. This is Chris Bumstead's fully loaded, stimulant-free pump formula, built to flood your muscles with blood, water and nutrients so every set feels fuller.
Because there is zero caffeine, you get the performance without the jitters or the crash, which makes it a good fit for late-night training or stacking on top of your favourite stim pre-workout. An 8g citrulline and 5g creatine dose anchors the formula, while nitrates and Alpha-GPC sharpen the mind-muscle connection.

When caffeine is not the goal but a big pump is, the CBUM Thuper Pump delivers. This is Chris Bumstead's fully loaded, stimulant-free pump formula, built to flood your muscles with blood, water and nutrients so every set feels fuller.
Because there is zero caffeine, you get the performance without the jitters or the crash, which makes it a good fit for late-night training or stacking on top of your favourite stim pre-workout. An 8g citrulline and 5g creatine dose anchors the formula, while nitrates and Alpha-GPC sharpen the mind-muscle connection.
Key benefits
- 8g L-citrulline to drive nitric oxide and vasodilation
- 5g creatine monohydrate for strength and cell volumisation
- 6.4g beta-alanine for endurance (the tingle is normal)
- 1g betaine nitrate plus 1.85g betaine anhydrous for power and pump
- Completely stimulant-free, use any time of day
Mix one scoop with 8 to 12oz of water and drink 30 minutes before training. Start with half a scoop the first time to assess tolerance to the beta-alanine tingle and the high-dose pump ingredients.
Good for lifters chasing the biggest pump possible, anyone sensitive to stimulants, and those who train in the evening and don't want caffeine wrecking their sleep. It also layers under a stim pre for the best of both worlds.
Does it contain any caffeine?
No. Thuper Pump is completely stimulant-free, so you can use it any time of day.
Can I stack it with a pre-workout?
Yes. It is designed to layer under a stimulant pre-workout for an even bigger pump.
What is the tingle?
That is the beta-alanine doing its job. It is harmless and fades as you train.
Does it have creatine?
Yes, a full 5g of creatine monohydrate per scoop, so you may not need a separate creatine product.
