I would go with xlevol instead of superpump.I'm not a rep,nor do i benefit from it,but i would like to see if others love it too,so i'm trying to get the word out.2 guys at my gym,a guy on here,and the guy at the store i bought it from love it too.(the guy told me as i was buying it it was good stuff,i didn't ask,just set it on the counter)
