CarnoSyn® is the only beta-alanine to undergo rigorous testing and ingredient QA. Tested on a wide range of athletic performance, including sprinting, cycling, rowing, and weight lifting, CarnoSyn® beta-alanine is clinically proven to:
By continuously increasing muscle carnosine through beta-alanine supplementation, CarnoSyn® supplementation led to an 80% muscle carnosine increase, after a 58.8% increase was observed at 4 weeks, exercise capacity is improved further in a consequence of muscle carnosine increase.
