Key Benefits

Insane Energy– Prosupps have formulated one of the most crazy pre-workout cocktails on the supplement market with 410mg caffeine matrix per serving. You have been warned.
Pump It Up– Arginine Silicate and l-citrulline are the key ingredients in this Prosupps' potion that break down to release nitrogen oxide in the blood and increase blood flow to the muscles. Muscles appear larger and leaner plus can work harder for longer due to faster oxygen and nutrient delivery.
More Lean Mass– The Mr Hyde formula features 1 gram of creatine HCl, the most tried, tested and trusted form of creatine, to promote lean mass and muscle hydration.
Refreshing Flavours– Mr Hyde pre-workout comes in a range of fiendishly good flavours including blue raspberry & fruit punch that mixed with water or stacked with Prosupps Dr Jekyll for a diluted caffeine kick without losing your muscle pump.

Who is ProSupps Mr Hyde Nitrox Pre-Workout For?
Prosupps Mr Hyde Nitrox is a hellishly strong stimulant blend and is reserved for hardened gym junkies only. Use with extreme caution! This product is not suitable for pregnant or breast-feeding women or children under the age of 18. For those with any existing medical conditions or prescribed medication please consult a medical professional prior to supplementation.
When to Use ProSupps Mr Hyde Nitrox Pre-Workout?
Shake up one 10-gram scoop of Prosupps Mr Hyde 60 minutes before each training session. Mr Hyde is an extremely concentrated caffeine formula – do not exceed one serving per day under any circumstances.

Half a serving of each) to give you just enough energy to train but without sending your head into a spin!
