So Ive been in and out of the gym for the past 3 months but Ive been consistant for the last 2 wks. However no matter mow much weight i am using (anything more then warm up weight) i get muscle fatigue around 6-8reps and shortly after failure.

Is there one supp that is better then others with improving muscular fatigue or endurance? Maybe just some simple creatine?

thanks bros
