For the athlete or bodybuilder who takes recovery seriously. Grunt is a potent and effective EAA formula packing 9 amino acids necessary for growing new and preserving existing muscle mass. Do not confuse EAA’s with BCAA. Although both are needed by the body and only provided via nutrition or supplementation, EAA’s are a complete protein source, whereas BCAA are not. Research indicates that EAA’s are best used as part of your pre-workout routine, while BCAA’s are most beneficial post workout due to their higher doses.
