Muscle Pharm did not kick off 2012 very well with their Hybrid N.O. Rumours are spreading and more importantly being added to about MP making a caffeine free version of Assault. This is the most important ingredient behind any pre-workout especially one that has no geranium in it. For a brand that is trying to colour in between the lines and make clean supplements for athlete’s in competition this would be a terrible idea. Caffeine is so powerful that it was on the WADA banned substance list, a few times. It is such an important piece of Assault why on earth would you want to make a version without it…? Of course, because athlete’s are not the ones asking for the caffeine to be removed.
