If you are looking for a high quality supplement to help you perform at your best, you should try Bodybuilding.com Elite Ultimate Stim Free Pre-Workout. This formulation has gone through a rigorous certification process by Informed Sport to ensure quality of its ingredients and is banned substance tested (1). This preworkout stands above the many commercial sports nutrition products that are potentially contaminated with banned substances or dangerous chemicals (2)(3)(4).

Many pre-workout supplements rely on stimulants such as caffeine, yohimbine, theobromine, and/or theacrine to help boost your performance. However, Bodybuilding.com Elite Ultimate Stim Free Pre-Workout was scientifically designed to help prime your body and mind before your toughest workouts without flooding your system with extra stimulants. You can take this preworkout before your cardio training, endurance workouts, and sport-specific activities without worrying about feeling too jittery. This is the perfect supplement to take if you have already had your morning cup of coffee, like to workout at night, or want to avoid unnecessary stimulants.

This formulation uses the available scientific literature to give you an effective dose of six proven performance boosting ingredients: 400 mg of PEAK ATP® (Adenosine 5′-Triphosphate Disodium), 2,000mg GlycerSize™ (Glycerol 65%), 3,200 mg of Beta-Alanine, 6000 mg L-Citrulline, 1,500 mg of Arginine Silicate Inositol, and 2,500 mg Betaine Anhydrous.

PEAK ATP® is relatively new but clinically validated to help increase your energy, muscular power output, and blood flow. This patented form of Adenosine 5’-Triphosphate (ATP) Disodium has a functionally identical structure to your body’s naturally forming ATP (5). A randomized, placebo-controlled study involving 20 trained males found that 400mg of ATP supplementation significantly increased resistance training performance and perceived rate of exertion over the placebo group (6).

Glycerol is a naturally-occurring sugar alcohol involved with carbohydrate and lipid metabolism. GlycerSize™ is a stable form of 65% glycerol powder that has the advantage of less clumping. When you consume glycerol, your body will rapidly absorb water, which will improve hydration, decrease urination volume, and improve muscle fullness (7). It can also improve your aerobic endurance by attenuating the effects of dehydration, reducing heart rate, and allowing better thermoregulation of heat (8). Studies have shown that glycerol supplementation can increase total body water by up to 700ml and can increase time to exhaustion during endurance events by 24% (7)(8).

Beta Alanine is a precursor to carnosine, which can help you delay muscular fatigue during high intensity exercise by acting as an intracellular pH buffer (9). A scientific study demonstrated that a daily dose of 3,200 mg of beta-alanine was able to delay the onset of neuromuscular fatigue during exercise (10). Other studies have shown that beta-alanine is safe, effective, and can increase lean body mass, number of repetitions performed, and overall training volume (11). It has also been shown to lower perceived fatigue during high volume workout (12).

Citrulline is an amino acid found primarily in watermelon, which promotes the synthesis and bioavailability of nitric oxide (13). A double-blind placebo controlled study found that supplementing a single dose of 6,000 mg of citrulline significantly increased nitric oxide bioavailability (14). These elevated nitrogen levels increase vasodilation and blood flow to your muscles, leading to better athletic performance in high intensity anaerobic exercises and less post-exercise muscle soreness (15).

Arginine is an essential amino acid found in various nitrite-containing foods, such as celery, lettuce, and spinach (16). Arginine is an essential substrate for the synthesis of nitric oxide and creatine (17). It also helps in regulating carbohydrate and lipid metabolism, lowering arterial blood pressure, and alleviating symptoms of type 2 diabetes (18). Arginine Silicate Inositol is a safe and stable, glucose-like structure, making it easier for you to consume and absorb (19). A double-blind placebo-controlled study found that a 1,500 mg daily dose of arginine led to heightened pre-workout energy levels, greater muscle pump immediately following a workout, and decreased biomarkers of muscle damage during recovery (20). A meta-analysis found that 15 studies demonstrated that both acute and long term arginine supplementation improve aerobic and anaerobic performance (21). One study found arginine to increase muscle blood volume through the production of nitric oxide, which demonstrates its ability to help you feel that muscular pump during exercise (22).

Betaine is a naturally-occurring compound found in seafood, spinach, beets, and whole grains (23). Betaine supplementation can improve exercise performance involving power output, muscular endurance, and overall body composition (24)(25)(26). Betaine may accomplish these effects by increasing rates of creatine synthesis, enhancing protein synthesis, elevating levels of blood nitric oxide, and promoting fluid and thermal homeostasis (27). A study found that taking 1,250 mg of betaine twice a day for a total of 2,500 mg was an effective dose to raise blood serum levels (28). A randomized placebo-controlled study found that 6 weeks of betaine supplementation improved body composition, muscle size, work capacity, and improved power in resistance trained men (26).
