You wanted a stronger, stimulant-based pre-workout and we listened. Not all Pre-Workouts are created equal! Rather than overloading RP Max pre-workout with every possible ingredient, the scientists at EHPlabs focused on ensuring the key attributes of a top quality pre-workout were focused on. RP Max has been tuned to maximize it's effectiveness as a high-stimulant pre-workout based on your feedback, so be ready to train!


The potent RP Max formulation provides the optimal central nervous system and adrenal gland stimulation to trigger a positive homeostatic energy release, improved cognitive ability by reducing the blood brain barrier, and enhance muscular and cardiovascular endurance.

RP Max pre-workout is also scientifically balanced to prevent a negative feedback physiological response to mitigate against post-workout stimulant crashes and adrenal gland exhaustion.



RP Max + Rachel

RP Max is formulated to be fast-acting through an ingredient called ‘Bioperine’. Bioperine is a trademarked ingredient that promotes the bio-availability of the CNS and adrenal stimulant active ingredients. As such, your body is able to absorb the various active ingredients at a faster rate, which promotes an almost immediate physiological and mental reaction!

The major CNS stimulants in RP Max that act as powerful energy amplifiers and mental focus enhancers include caffeine, guarana seed extract and yerba mate leaf extract.

RP Max also utilizes clinically studied ingredients taurine, beta alanine, choline bitartrate and tyrosine in optimal ratios which act as antioxidants, acid buffers and mental focus enhancers that allow you to work out for longer at higher intensity, delaying any symptoms of fatigue and lethargy.

RP Max


RP Max is an optimal addition to morning and lunchtime workouts.

Take 1 scoop of RP Max with 8-10 oz (240-295 mL) water 15-20 minutes before your workout. DO NOT exceed 1 scoop per day.

To get the most benefit out of RP Max, we recommend that you only use it on training days and avoid use within 5 hours of your bedtime due to its stimulant-based nature. If you are training later in the day or at night, we recommend the use of PSI non-stimulatory pre-workout in place of RP Max.


RP Max works optimally when used together with PSI. The PSI and RP Max stack will fine-tune your performance output for each workout, ensuring you are in the optimal physical state to achieve your fitness goals!

Pre-Workout Stack

This combination should only be used in the morning or for lunchtime workouts due to the stimulant-based nature of RP Max.

RP Max can also be used in conjunction with Beyond BCAA’s, L-Carnitine and OxyWhey Protein but should not be combined with OxyShred. RP Max may be stacked with OxyShred, but never taken at the same time due to high levels of caffeine.


Will I Crash After Using RP Max?

RP Max pre-workout is clinically dosed to focus on stimulating the CNS and reducing the blood brain barrier to improve focus and cognitive ability, and should not cause any pre-workout crash. The scientists at EHPlabs have ensured the optimal dosage of caffeine has been added to RP Max, which means you will not burn out your adrenal glands and release excessive cortisol (the stress hormone which causes post workout crashes).


Ingredient profile

  • - Beta Alanine – is a well researched ingredient that is used in many pre-workout supplements. Beta Alanine is the rate-limiting component in the synthesis of Carnosine in the body, so by using Beta Alanine you can increase your levels of Carnosine13 which acts as a very powerful anti-oxidant and also as an acid buffer within your muscles. This helps to delay the feeling of fatigue and exhaustion13 which allows you to workout longer and harder. Beta Alanine has been suggested to enhance muscle contractility, improve explosive power and increase aerobic energy production. 6 13


  • - Taurine – is a naturally occurring amino acid that is a powerful antioxidant helping to decrease muscle damage and soreness, helps to improve strength levels,19 metabolize fat, promotes insulin sensitivity and blood glucose control,3 improves heart health and helps to improve both mental focus and reaction time.  


  • - Choline Bitartrate – helps to delay fatigue during strenuous prolonged workouts, plays a role in fat mobilization as it is a lipotropic agent (stops deposition of fat) and is crucial for nerve health and signalling.4,7


  • - L-Tyrosine – is a naturally occurring amino acid that enhances alertness and cognitive performance, especially in demanding situations (eg. heavy workouts), is involved with neurotransmitters and plays a role in the production of epinephrine and dopamine.8 It helps to alleviate stress, and helps with recovery from fatigue without any jittery side effects. When taurine is combined with tyrosine, they work synergistically12 and EHPlabs studies found there is a lift in mood and overall focus.


  • - Caffeine Anhydrous – is a CNS stimulant that acts as an energy booster and also boosts metabolism by increasing free fatty acid mobilisation.5 It improves the contractile function of muscle, muscular strength and performance in intermittent bouts of exercise.11,16


  • - Guarana Seed Extract – is a CNS stimulant containing theobromine and theophylline, which acts as an energy booster and enhances the effects of caffeine1. It also helps to improve mental focus.14


  • - Yerba Mate Leaf Extract – is a CNS stimulant used to relieve fatigue which also possesses antioxidant properties.2, 14


  • - Advantra Z® – increases energy levels, your metabolic rate (thermogenesis) and is effective in reducing body fat through accelerated lipolysis.10

  • - BioPerine® – has a synergistic effect with caffeine to increase absorption of vitamins and nutrients, improve thermogenesis and may improve fat metabolism.17


  • - Vitamin C - essential for the proper functioning and boosting of the immune system and also plays a crucial function in growth and muscle repair.15


  • - B Vitamins - essential B-Vitamin complex for energy production, synthesis of new cells and repair of damaged cells.18
