For the serious athlete or bodybuilder. Grunt® is a highly effective EAA formula that contains all nine amino acids required for muscle growth and maintenance. Contrary to popular belief, EAA’s are not synonymous with BCAA’s. While both are required by the body and can be obtained only through nutrition or supplementation, EAAs are complete proteins, whereas BCAAs are not. According to research, EAA’s are most beneficial when used in conjunction with a pre-workout routine, whereas BCAA’s are most beneficial post-workout due to their higher doses.
