• 10 Icy Blue Razz

I have used this product for years and I find it really good. Taste, pump, energy and then no crash

• 5 Fruit Punch
• 5 Icy Blue Razz

I have been drinking this stuff for at least the last 5 years. I like it. It tastes good. Works good. Not sure if this can continue. I can kinda see they are adjusting the formula a bit. Lately they seem to be doing better on the clumping, so that’s good. I like the icy blue raz and the fruit punch. The only problem is that the amount of dye. This stuff is soooooo bright I mean they cranked the dye up to 11+. Please take some of the dye out – it does not need to be so intense. There is no reason to be drinking this much dye – I mean … dude - holy crap that’s a whole lotta dye. Just cut they dye back like 80-90% or so and the stuff will still be super bright. Seriously though, I loved the Pineapple flavor. I hope that comes back. It was really good and was not loaded with so much artificial color.

I like the feeling after I take it I have Energy When I go to the gym

If it isn't used regularly the powder will lump up and make it impossible to scoop out.

• 10 Tart Candy Explosion - Candy Shoppe Series

The Tart Candy Explosion has a great taste and doesn't stain my lips when drinking it. 8/10 only because I need 2 scoops of Original to actually help. If this was offered in the extreme energy line I would use that. But the taste is so good it's hard to go away from it!

Flavor is good, but not enough "punch".

• 2 Icy Blue Razz

Icy Blue is sooo blue that it dyes anything it touches. :-(

Product mixes well and tastes good. Helps me power through those 5am workouts. Plenty of energy, alertness, and drive without feeling jittery.

• 3 Icy Blue Razz

Purchased Icy Blue Razz. When I mix it in water, I felt it has too much of blue color and it leaves my shaker stained with the blue color. Also after drinking my tongue is all blue which is too bad. Doesn't sound healthy at all considering too much color being put in this. Disappointed with C4 on making such a product with too much of color in it. Have used Fruit Punch flavor before and that was fine and not much color.

Used this for years since I started working out. Moderate caffeine level and it kicks in 15mins or so. One of the best ways to wake up your body after a long day at work. Highly recommend (especially for beginners).

Overall not a bad product. You don’t get edgy at all from using this product. But after a couple weeks I did notice that theeffects are not as long-lasting. Pretty good stuff for beginner level, after which you have to increase in dosage to about 2 to 3 scoops for eight ounces. Flavors are bad either, you don’t get that chalky taste.

Did not feel the beta alanine (I currently use ON Beta alanine powder, which i can feel it work). The caffiene was perfect for me. Did not improve my pump. Purchased in store.

• 8 Orange Burst

In my hunt for a pre-workout (never used any or even drink coffee ever), I was given 3 samples of different brands. C4 Original was one of them. After about 20 minutes, beside feeling some tingle on my ears and scalp, it didn't provide any pumps or extra energy after a long day at work. Orange Burst tasted good though. Overall, I'm pretty disappointed with the lack of results and won't go back to it, so I will try the samples from other brands/products to see how they fare.
