I tried this product because I needed some added energy with my personal training sessions and I must say this is the best. I'm now using it for all my workouts and I feel like a beast in the gym. Please take as directed (30 minutes) before workout to receive the maximum results.

Powerful.....Focused.....Feel Amazing About Yourself.
I highly recommend this stuff. I started off taking a scoop right wen I got up and 10 mins later....WOW!! It gave me massive amounts of energy, and enough focus to beat my reps from day before. You go and go until you cant lift ur arms and wait just a few moments and ur able to power thru another set. Best stuff I've ever tried. And the energy throughout the day is the best part, not only do you look good but you also feel I'm not saying u can eat watever you want and do this, u still need to eat healthy. I am now taking 2 scoops every morning it's that good.

Really good pre workout
Awesome pre workout. Got the jitters a little bit so I've been doing a little less than a scoop. Good pump and energy.

I love the C4. My first taste I was a little put off because it tasted like cough syrup. But I got use to the taste. The AWESOME part is within 15 minutes I have so much energy. I go workout and feel really motivated. The best part is it doesn't wear off quickly. I usually workout around noon and the C4 gives me the energy to do the workout and still feel charged up to tackle other chores. C4 also doesn't give you the feeling crashing when it wears off.

Not impressed
First time trying C4 and was not impressed. Didn’t give me any energy just the not so great pre and post side effects. It made me so focused in I felt like a zombie and had no drive.

I just tried this new version of the C4, it's explosive energy, fast acting, a lasts a long time. If your a low energy person who caffeine don't work for them like me this is perfect for your workout rutien. But you better be ready to work, cardio for sho weight lifting an more i kept going for over a hour an still haven't burned the energy off. Take a half a spoon to excess of how much u can take, it's great for after work an your too tired to work out, you drink this an be ready to go!!!! It makes u hot an tingaly like pins an needles only take it if your ready to sweat an burn the energy off, it's not for the average workout, an try not to over do it ur body makes u believe u can keep going.

Excellent product
Seriously, if you think you feel the pre workout, then you'll feel this one even more. Tastes great, you feel the energy, great product.

Pretty good.
I got this product about 2 and a half weeks ago, and so far so good. Definitely gives you a good pump and more energy. However, the taste isnâ??t that good, when u mix it, there are usually chunks at the bottom, and the â??light tingling sensationâ?? is more of an annoying itching sensation. But still, does what itâ??s mean to do pretty well.

A shopper on Mar 1, 2018
BEST ANSWER: I started getting results quickly but I also workout everyday for 1 hr to 2 so as long as you put the effort in the results will come
I'm a 56 year old man been lifting weights for 44 year's will this help me put on more muscle ?
Cutup on Feb 26, 2018
BEST ANSWER: It will definitely energise you and provide some nutritional supplements that can help, but it isn’t enough by itself, you’ll need a diet and lifting routine conducive to building muscle for that.
