PreRace provides all the necessary ingredients needed to increase mental stamina, increase time to exhaustion, increase maximum workload, improve mental clarity and increase oxygenation of muscles.

PreRace contains a mental acuity component comprised of DiMethyl Amino Ethanol (DMAE), metabromine and catechin, which combine to deliver a clear mental focus prior to exercise.

Citrulline Malate and L-Taurine improve cardiac output, stimulate the nitric oxide (NO) system and clear lactate.

The proprietary formula works synergistically with quercetin (a powerful antioxidant that improves time to exhaustion in endurance athletes) and 200mg of caffeine (Red Bull has 80mg caffeine), 3,000mg taurine (three times the amount in Red Bull), 350mg quercetin and a proprietary neurostimulant blend.


South Dakota State University conducted an independent study on PreRace powder to determine its effectiveness on cycling endurance. The double-blind placebo controlled study used seven trained cyclists in a 40K time trial. Each cyclist performed two 40K time trials.

On the first TT, the cyclist consumed either a placebo or PreRace mixed with one serving of EFS 30 minutes prior to doing a 40K TT. One week later each cyclist would switch the protocol and receive the opposite of what he/ she received the previous week.

Time trial was 3:17 faster than with the placebo

Watts increased by 15

Lactate threshold increased




CM is a mixture of citrulline, an amino acid involved in the urea cycle, and malate that has been shown to stimulate nitric oxide.  The fact that nitric oxide increases blood flow should make it of interest to endurance athletes, as increased blood flow will serve to deliver more nutrients to muscles, thus helping muscles become more resistant to stress. The stimulation of NO has also been found to increase glucose transport in skeletal muscle significantly (Balon et al., 1997). The fact that nitric oxide acts to reduce inflammation should also make it of interest to endurance athletes as it has the potential to reduce the pain associated with subjecting muscles to extreme stress.

Two maximal cycling tests were performed with one group ingesting CM and another group ingesting a placebo. Aerobic-Anaerobic threshold was significantly higher in the CM group and 27% of subjects were able to achieve a higher maximal workload on the second test. (Janeira MA, 2006).

Malic Acid

Malic acid is the only metabolite of the Krebs Cycle which falls in concentration during exhaustive physical activity. Malic acid is involved in the production of energy in the body under both aerobic and anaerobic conditions. During anaerobic conditions, malic acid has an ability to remove the accumulation of reducing equivalents. Human studies have shown that after endurance training, athletes’ muscles were characterized by a 50% increase in the malate-aspartate redox shuttle enzymes. In both animals and humans, when there is an increased demand for ATP there is an additional demand and utilization of malic acid. Malic acid stimulates oxygen consumption by increasing mitochondrial uptake of other substrates. It also stimulates the removal of components that build up under hypoxic conditions and inhibit ATP production (Wu J et al 2006).


Caffeine stimulates the central nervous system (CNS), increases the release of adrenaline, increases the use of body fat as fuel and spares glycogen. Adrenaline release is accomplished through caffeine’s effect on epinephrine and nor-epinephrine. Many athletes seek this CNS excitatory response to increase alertness and to give them the extra ‘energy’ needed for their workouts. More importantly, caffeine mobilizes free fatty acids (FFA) in the blood. Increased FFA in the blood allows the body to use fat as a fuel source. The use of fat as fuel allows the body to spare glycogen (carbohydrates) for later use in exercise.


Through its cardio and oxidative protective roles, oral administration of taurine can improve exercise performance significantly. Furthermore, pre-exercise taurine administration can reduce muscle damage caused by endurance training. Researchers also theorize that it is through the cellular protective properties that taurine attenuates exercise-induced DNA damage and enhances the capacity of exercise.


Quercetin acts to potentate the effects of caffeine. Quercetin is reported to help control cyclo-oxygenase activity. Cyclo-oxygenase activity increases in the body during periods of high physical stress (Garcia-Mediavilla V et al.). Studies indicate this powerful flavanoid works synergistically with theobromine and caffeine to further extend the CNS stimulant effects.


Q: How should I use PreRace?

A: For best results, only use PreRace once or twice a week. Take a serving 30-45 minutes before your training or racing. Only use PreRace in really difficult workouts (e.g. interval training) and races to help you to push past your normal limits. Make sure you give yourself plenty of time to recover from this intense training or racing before doing your next demanding workout or race.

Warning: Start with half the recommended dose to assess your tolerance.  Not intended for use by persons under the age of 18.

Q: Should I use PreRace powder or the PreRace capsules?

A: This is more a matter of preference than anything else. For some, adding PreRace powder to any drink they like is very convenient. Many like to put a scoop right into the EFS Liquid Shot flask or their EFS drink. For others, capsules are more convenient, easier to take, easier to carry and take the flavor obstacle out of the equation. PreRace powder will get absorbed faster and because it is a 5.5g scoop there is simply more active ingredients per serving than the 3 capsules. For long distance racing some athletes may prefer taking a three capsules periodically throughout the event. The powder is great for certain circumstances and the capsule is great for other situations. In the end it comes down to personal preference.

Q: What are the benefits of using PreRace for training and Racing?

A: The benefits include:

1) Enhances oxygenation of muscles
2) Increases muscle stamina
3) Increases nutrient absorption by blood
4) Improves time to exhaustion
5) Increases maximal workload
6) Improves oxidative ATP

Q: Should I use PreRace only for racing or is it good for training also?

A: There are a number of other benefits to using PreRace in training. It will give you a number of opportunities to see how your body reacts to PreRace. People react differently to PreRace. Using it in training allows you to test different doses. That way, on race day you’ll not only be more fit, you’ll also know exactly how you like to use PreRace.
