HYDRATION & ELECTROLYTES
PRE Stim-Free contains key electrolytes and minerals that help preserve proper cellular hydration that can not only aid in muscle pumps but also maintain heightened performance to keep the intensity high throughout the workout without hitting the wall early.
L-Leucine: An essential amino acid used to boost protein synthesis and help increase ATP to be used as energy.
Beta-Alanine: This common yet potent ingredient can increase performance, reduce fatigue, heighten focus, elevate muscular endurance, and supports muscle growth.
Creatine Monohydrate (PharmaPure™): A patented ingredient that may support muscle growth, improve performance, boost strength, and increase energy.
Betaine Anhydrous: This powerful ingredient is beloved by all thanks to its ability to help improve power, enhance muscle pumps, improve hydration, and support protein synthesis.
Magnesium Creatine Chelate (Creatine MagnaPower™): A patented form of creatine that has been shown to help increase the bioavailability of creatine and magnesium, increase ATP production, support muscle growth, improve cellular hydration, enhance performance, boost strength, and reduce muscle soreness.
L-Citrulline: Found to support athletic performance and increase plasma levels of arginine to improve vasodilation, blood flow, muscle pumps, and nutrient transport.

What is the best way to take PRE Stim-Free?
- Mix one heaping scoop of PRE into 12-14 ounces of water and consume 30-45 minutes prior to training.
Aren’t stimulants the only thing that make pre-workouts effective? Why wouldn’t you put them in the formula?
- Absolutely not. While there is no doubt that certain stimulants, such as caffeine, can improve performance, they are not the only ingredients in a pre-workout that provide an ergogenic benefit. For example, the creatine found in PRE Stim-Free is the most studied and effective performance-boosting supplement ever and is not considered a stimulant. We left stimulants out of this formula to accommodate individuals who are sensitive to stimulants, hit the gym late at night, or otherwise want a performance-enhancing pre-workout without stimulants.
I heard creatine can cause kidney problems and cause cramping. Is that true?
- Absolutely not. Creatine is the most studied and effective supplement ever... period. Over 500 studies have been done on creatine, and none have shown to cause any adverse side effects. However, you should expect to see big improvements in strength, power, and endurance after taking creatine.
What makes PRE Stim-Free better than other stimulant-free pre-workouts?
- A lot of other stimulant-free pre-workouts use ingredients that are ineffective or not properly dosed. All the ingredients in PRE Stim-Free are research backed and dosed efficaciously based on the current scientific literature.
