MuggPro: I'm only about 140 pounds and I don't take stimulants but when I do I have to take quite a bit.. With this preworkouts I took 2 scoops so I could get any feeling towards it.. The first time i too it i only took 1 scoop but didn't feel a thing. The next day I took 2 just to get a pump in my workout an even then it was all that much:/ 2 and 1/2 is how much I have to take to actually get a true pump in my workout

Hustle and fitness: How would it possibly make you weaker before stronger? When the whole purpose of a pre workout is to wake you up and make you focused.. No pre workout makes you stronger. You guys just need to train harder
isaias torres: I asked the "nutritionist" at my gym what this was and she said it's basically crack for gymnasts lol LOL
chris greener: How many scopes would you recommend I have I'm 16 yes I know should be 18. I'm 6 foot 2 inches and weigh 97 kg
HolyWhisp: I'm looking for a pre-workout to add to my routine, currently the only supplement I use is why protein post-workout. Looking for something to add before I hit the gym and this looks to be good value for money with good reviews, but would it be recommended for somebody who already has a rather nervous/anxious disposition ?
Teny John: It's says if have liver problems don't take... But I have fatty liver ... Can I take this supplement??
Luis Morales: I saw thi at Costco im planning on buying, but im kinda overthinking it.. im kinda a weak stomach dude wat are some good benefits and bad tings about it tht can help me or not?
Kap Bab: This makes me crap like a mother freaker how can I stop this
paramrider 69: STAY AWAY FROM THIS DANGEROUS PRE WORKOUT MY BROTHER HAD HEART PALPITATIONS AND WAS RUSHED TO HOSPITAL. They said that there were undisclosed ingredients within this product that created a subtle "meth-like" high. Stay safe fellow lifters, i only look out for u
Derrick Thompson: During football season I took this and I can honestly say it was by far the craptiest stuff ever made me have anger lashes here and there and made me weaker before stronger. Btw high school football players dont need this crap find something better
Jon Kizuka: should i take this with a pre-workout meal? if not how many minutes before working out of after a good meal to take this?
Justin Wells: I love C4 in my opinion it is the best pre workout out there atleast that I have tried it does not make you crash either which is great Love this stuff I have really increased by weight and get alot better workouts!! In my opinion the best flavor is Pineapple also get the 60 serving on Amazon its about $37.99 alot of places really overcharge on this product. Good Luck.
