Works Great, taste great
I think that this product is great, and I did not experience any itching until the other day and it was mild.

I use it regularly and like the taste
I like it! Gives a nice energetic pump to my early morning workouts. A slight tingle but not anything bothersome like other pre workouts. The taste is good, I prefer the orange mango to the blue raspberry. I recently tried the pre mixed C4 Ultimate in the cans I liked it better but its pricey so buying the powder mix is more affordable. This also contains creatine.

I like this product I hydrate during workouts with this and find that I have the ability to squeeze out 1-2 extra reps and do negatives with greater intensity. I do not notice an aftertaste with this product which is a huge bonus.

Turns your mouth blue.
It works well. It only gets 3 stars because it turns your tongue and teeth blue.

So if you want to look like you just blew a smurf then this is the product for you.

amazing pumps and energy
By far the best preworkout I have taken for pumps and great energy. I have taken it for 4 months now without changing it up and it works everytime like its the first. Highly recommend it

Just ok. Energy doesn't seem to be as high as other pre workout drinks.

Excellent product - 10/10
Very quality taste, but more importantly, performance. Lots of energy, but a much better focus component than I have experienced in other pre workouts. Have taken multiple times and always feel locked in. Mood always feels good during the lift and the focus remains high for several hours post workout. No energy crash. Very quality pumps. Overall very satisfied. 10/10

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.
Do you feel like a zombie when the effect goes out and you crash?
