Powerfully dosed pump-based pre-workout formula
6g L-Citrulline, 5g Glycerol Monostearate, 3g AAKG

Pump Pre-Workout

Our stimulant free, pump-based pre-workout formula, loaded with 9 active ingredients including L-citrulline, AAKG, OAKG, creatine and taurine to help you get the most out of your training sessions.

Pump Pre-Workout™ is a comprehensive pre-workout formula that’s totally stimulant free. That means it’s not loaded with caffeine, like traditional pre-workouts. Instead, we’ve packed it with 22g of active ingredients, split between 9 ingredients in high doses, creating a comprehensive pre-workout that’s appropriate for evening and late-night training sessions.

Pump Pre-Workout™ is potentially the most advanced pump-based pre-workout formula on the UK market, containing an impressive blend of unique ingredients that combine to provide a synergistic effect to aid you through your workout.

  • L-Citrulline
    L-Citrulline is one of the most widely recognised pump ingredients, and we’ve dosed each serving with an impressive 6g measure.
  • Glycerol Monostearate
    Glycerol monostearate is a hygroscopic chemical – that means its primary function is drawing in water. That’s why we recommend consuming Pump Pre-Workout™ with lots of water.
  • Arginine Alpha-Ketoglutarate (AAKG)
    AAKG is a highly bioavailable form of the amino acid arginine, making it one of the most popular pre-workout ingredients in the market. Each serving of Pump Pre-Workout™ contains an impressive 3g of AAKG, double the dose of most competing products.
  • Ornithine Alpha-Ketoglutarate (OAKG)
    Ornithine, arginine and citrulline each contribute to the same cycle in your body, so we added a dose of OAKG to complete the dose and provide your body with a steady supply of fuel.
  • Creatine Monohydrate
    One of the most popular and widely researched supplements in sports nutrition, creatine helps to increase physical performance during successive bursts of short term, high intensity exercise. We added a 3g dose to this formula to support your workout.
  • Taurine
    A popular ingredient in many energy drinks, taurine is a naturally occurring amino acid commonly found in skeletal muscle.
  • Beetroot Extract
    Relatively new in sports nutrition, beetroot extract is a rich natural source of nitrates and has been subject to several recent studies in exercise performance.
  • Pine Bark Extract
    Another new ingredient, our pine bark extract is standardised to provide 95% proanthocyanidins, which are a class of polyphenols. We packed a 200mg dose into each serving of Pump Pre-Workout™.
  • Vitamin B6
    As a final touch, we added 5mg of vitamin B6 to this formula to contribute to a reduction in tiredness and fatigue.



The Purpose

Pump Pre-Workout™ is suitable for anyone looking for a potent, highly dosed pre-workout formula without the stimulant overload. Because this formula doesn’t contain caffeine, it’s ideal for evening and late-night training sessions, or anyone who wants to cut down their caffeine intake. Because it contains both glycerol monostearate and creatine monohydrate, we recommend drinking each serving with at least 500ml of water, and continuing to drink water throughout your workout. For this reason, it’s also better suited to submaximal lifting sessions than intense cardio exercise.


  • Perfect Pre-Workout
    The ideal supplement for pre-workout, giving you the nutrition you need to seriously train.
  • Stimulant Free
    Contains no caffeine, ideal for evening and late-night sessions.
  • Optimal Doses
    Dosed to optimal levels to provide the nutrition you need.
  • Combined Action
    By blending unique ingredients with different purposes, you get the best potential in a single supplement.



Mix 1 scoop (approximately 26g), with 500ml-1000ml water. Pump Pre-Workout should be used approximately 30-45 minutes prior to training. We recommend consuming plenty of water throughout your workout.

Contains Silica Bag - DO NOT EAT.


This product must be consumed with lots of water, otherwise it can cause dehydration.
