c4 is the weakest pre I've probably ever tried. EVL is right there with it, but if someone is like 100lbs and never takes preworkouts
and don't really train harder than like 3 sets of 10 on everything, they should work fine.
C4 has actually been reformulated but the previous version at 2 servings does give a good kick of energy and
a decent pump but the problem with it is that you become tolerant to the stimulants in there very quickly that's why
I always recommend rotating stims each and every workout but I haven't tried the new version yet. Now EVL ENGN
I beta tested that PW for the company and in my final review I suggested a few things to make it better and they actually
listen to me and did add a decent blend of ingredients for good focus but people who are use to heavy stimulants don't
feel the energy from ENGN because they only use caffeine has the energy stimulant. When I do use ENGN I feel the focus
ingredients kick in before the caffeine and again this is one that you will build a quick tolerance to so rotating is how I suggest
getting around the tolerance of using the same stimulant everyday.
