C4 is the definition of a tried & true go-to PWO for pretty much anyone out there. It's a hell of a product and whether you've been training for years or just getting started, C4 is most likely for you! This product is insane. Helps me keep focused, gives me insane amount of energy to finish my workout and no jitters or unwanted effects.I combine this with Naturabest Garcinia Cambogia because it’s another awesome product that has helped me get lean while building muscle which is the wanted effect on this end. I'm always wanting to eat a truck after my workouts but Garcinia helps me control my portions and not overkill. Both highly recommended.
I'm not sure what happened, but I got a bad container. The powder was white with some blue mixed in, and it tasted awful. Not like the normal delicious flavor. Hopefully this is a one-off because the product itself is amazing. Contacted Amazon after my return was rejected and they were super helpful getting me a refund. Mostly posting this in case anyone else has this experience!In the picture, you can see the color it's supposed to be in the scoop (I have a lot of this in my house) vs. the color of the container I got.
I have now purchased 2 Jars of the C4 Creatine Energy Supplement.My first purchase was the Blue Razz Flavored C4.Now I am trying this Fruit Punch Flavored C4 Creatine Energy Supplement.I must say, that even though the Blue Razz Flavored C4 was not bad tasting at all, I really like this Fruit Punch Flavor also.This stuff helps to keep me going in the middle of a tiring workout.After taking the Fruit Punch Flavored C4, I was able to complete my final workout for the day with the help of this supplement from Cellucor. I had a bit more of energy and I was able to do other activities after my workout also.The scooper that is included with this product is not large at all. I have used products of this type in the past and the scooper was huge compared to this C4 Energy Supplement. And with a scooper size from other products being so large, sometimes I had an upsetting feeling to my stomach after consuming so much of the other powdery / chalky substance. So the small scoop of this C4 Supplement was very much welcomed.This supplement does contain Caffeine, so I would suggest that you don't take this soon before bedtime.Since I had a boost of energy to complete my cardio workout at the end of a very strenuous and exhausting day, I would certainly purchase this product again and will be recommending to my workout friends, that they also try this energy boost supplement.EITHER Flavor will satisfy you.Just so you know, I received this product at a discount in exchange for my honest and unbiased review. But this in no way has influenced my opinion of this fine product.Can you please do me a favor ?If you have simply enjoyed reading my review or if my description has helped you in any way, could you PLEASE mark my review as "Helpful" please. I would REALLY Appreciate that and it helps encourage me to keep writing reviews of my purchases… Thanks :-)..
I've been pretty satisfied with C4, but it still falls just shy of 5 stars. First, there's too much beta alanine. That burning sensation ("paresthesia") is a symptom of too much at one time. 1 gram max per dose is enough. Any more can just be supplemented throughout the day to improve carnosine levels. As for strength and pump, it's pretty good. Although having everything packed into one product just seems like a waste. I'd rather use Skald Powder, Strawberry-Lemonade flavor, because it means I can keep my energy separate from my creatine and vasodilators, and then add what I need when I need it. Sometimes I need more strength, so I'll dose creatine. Sometimes I don't want any creatine at all, especially if I'm cutting weight. But every workout needs energy. Skald also tastes and mixes better than C4 (probably because it isn't loaded with all that gritty creatine), and the respiratory support aspect is always appreciated. Just the same, C4 is still a really good pre.
 []The Icy Blue Razz flavor I bought arrived sounding like a maraca. Obviously this is supposed to be a powder, so I decided to video the "unboxing." Some of it is still powdery, but a lot has hardened up into chunks of varying sizes that make up maybe 1/4 to 1/3 of the total product. If I had a pestle and mortar I could use this as it was intended, but not in its current state.One of the pictures clearly shows that the root of the problem is that it was never closed all the way. When I tightened the lid back on after breaking the seal, you can see a solid inch between where the product seal began and where it should have. Their lid machine needs to be reworked, and quality control chatted with because this was clearly a factory error.Unfortunately this also explains why 14% of the reviews for this product are 1 star; based on other reviews, this happened to others too. Guess it wasn't my lucky day either.
I got this item and it was ruined the first time. It seemed like some moisture got in the powder and it made it clump together. I emailed the company and they asked for a picture of the defective item, sent them a picture and they refunded me immediately. They were great in customer service!!!I'm not big on caffeine so I first used this and was taking a half a scoop. It was so strong that it was giving me headaches. Tried it with a half a scoop for two days and realized that was too much for me. I don't really drink things with caffeine in it. Now I am using it but pouring in a quarter of a scoop and it works great. I have pleanty of energy when going to the gym. I highly recommend this product. It's great!
