BSN N.O.-Xplode is a preworkout supplement that contains ingredients intended to promote energy, endurance and muscular strength. BSN N.O.-Xplode is typically used before weightlifting workouts, but may be effective for other athletic pursuits as well. You should consult a doctor before using this or any other supplements.

Caffeine, also known as methylxanthine, is a main ingredient in BSN N.O.-Xplode. This stimulant is also found in coffee and soft drinks, and may increase your energy levels. However, research led by M.A. Addicott and published in the October, 2009, issue of the journal "Human Brain Mapping" notes that regular caffeine use can decrease blood flow in your brain, which can interfere with cognition.

Creatine Ethyl Ester

Creatine ethyl ester is a form of creatine, a naturally occurring amino acid. Creatine is present in many sports supplements, and research led by E.S. Rawson from the November, 2003, issue of the "Journal of Strength and Conditioning Research" explains that creatine supplementation may enhance muscular strength increases resulting from resistance training.


L-tyrosine, also known simply as tyrosine, is an amino acid that helps build neurotransmitters, notes the University of Maryland Medical Center. This amino acid is purported to improve athletic performance, but the center explains that there is no research to support this claim.

Arginine-Alpha Ketoglutaric Acid

Arginine-alpha ketoglutaric acid, also known as arginine AKG, is a supplement intended to increase production of nitric oxide, which may increase blood flow, resulting in improved nutrient delivery to your muscles. However, supplement and fitness expert David Barr explains that research indicates arginine AKG is not very effective at improving blood flow, and does not improve muscle mass.


Beta-alanine is an amino acid that may improve your muscular endurance. According to Dr. Jeffrey R. Stout, research indicates that beta-alanine is more effective than creatine at preventing fatigue and allowing you to exercise longer.
