Delicious & works great
I was very skeptical about th flavor "orange mango" naturally because i dislike orange flavor but I received a free sample and gave it a go. The taste is wonderful its like Sunny D when you're on a strict diet and it gives me a great tingle but nothing to wear I feel crazy. Definitely a must try.

Best Pre workout
I bought after receiving a sample. I have more energy to get an intense workout in and it does not give me jitter.

This product taste good but that is about it. The product itself does not give you the boost of energy you need and it seems to wear off too quickly in your workout. I would recommend to make the product have more boost of energy and longer endurance to sustain through a workout. I workout in the early morning so I rely on my pre workout to wake me up and give me the energy I need to get my work out in.

Ultimate Orange replacement!!
In the late 90's I had been using Ultimate Orange since the day it hit the market until it was banned. The gym was my sanctuary and the ban really hit home. Working midnights, my kick for my workouts was gone.

I never, and I repeat NEVER, thought I would find a replacement. Last week I tried C4 Ultimate for the first time and it immediately took me back to the day I last used Ultimate Orange!!! What a truly amazing product!!! I absolutely LOVE this stuff, period!!!

Great flavor!
I was really excited to have this flavor, especially given it has been a 100+ degrees out lately, stupid heat wave. It definitely hit the spot though, very refreshing and slightly tart from the lemonade aspect making it a great flavor for summer. Though the Raspberry is a bit lost in that it tastes more like a generic ‘Berry’ taste more than anything it is still delicious; if they did not specify raspberry on the label I would not be able to off-hand pick that as the flavor. I would compare this to the Raspberry Lemonade Crystal Light but with a slightly more sweet flavor, making it have a bit less ‘bite’ to the tartness, so you get the lemonade feel but it is not too overbearing, keeping the flavor well balanced.

This is another winner of a flavor, and definitely worth grabbing if you want something a bit less sweet than the Orange Mango or Strawberry Watermelon.

Good Stuff
C4 Ultimate is the first preworkout that I have ever gone back and bought the same one as I just finished. Usually I switch every month because they start being less effective after a month. Not so with C4 Ultimate.
My only beef, what happened to just plain old orange flavored? I'm not fond of all the mixes and in the end, they all seem like someone melted down skittles and added them to water......

Half a Scoop Worked Great!
I usually don't take preworkout because I am extremely sensitive to it. But I decided to take a ride on the wild side and took HALF a scoop before my workout today. Best pump I've had in a long time and I did not feel any negative side effects! I will definitely be using this again!
