DENVER, CO--(Marketwired - Apr 28, 2014) - MusclePharm Corporation (OTCQB: MSLP), a leading international, award-winning sports nutrition company, today announced that Nutrition Research, an international publication for nutrition to advance food and life science research, published the results of a double-blind placebo-controlled clinical study demonstrating safety and efficacy of MusclePharm's pre-workout supplement Assault™.

Results from the trial indicate that the regular use of MusclePharm's pre-workout supplement is safe to consume daily in healthy, recreationally-trained men. In addition, Assault may assist in improvements in lower body strength and ventilatory threshold, the point in progressive exercises at which the first respiratory changes begin to take place. No adverse effects were noted for kidney and liver clinical blood markers, resting heart rate, or blood pressure after the 28-day supplementation period, as tested in the clinical trial protocol.

"Our team of doctors and researchers has done an amazing job creating the only pre-workout supplements on the market that have been clinically proven to safely enhance performance," said Brad Pyatt, Chairman and CEO of MusclePharm. "By taking a science-based approach to product development through our six-stage research protocol, we continue to set the bar in sports nutrition as the leader in innovation and science, giving athletes confidence in the safety and efficacy of our products."

The study was conducted at the United States Sports Academy in collaboration with Georgia Southern University, Statesboro, GA, and the University of Mobile, Mobile, AL.

The paper "Ingesting a pre-workout supplement containing caffeine, creatine, beta-alanine, amino acids, and B-vitamins for 28 days is both safe and efficacious in recreationally active men" is available online ahead of print addition of the print edition at
