The story of becoming one of the first NFL certified pre-workout stacks. It's all because athletes like @bkaufusi90 @corbin_jk & @kf_strongman believe in Muscle (GroBuff back then) and the results they get 💪 It's a humble beginnings story, and we'll never forget those that have been with us from the start 🙏 #klerpath #muscle #quietconfidence #preworkoutstack #nflcertified #supplements #nutrition #workoutfuel #muscleflush
