Ultimate Pre-Workout with Zero Sugar, Icy Blue Razz, 20 Servings

I love this product, but since ordering it a week ago (August 2026), the label shown by Amazon for some flavors has changed and is incorrect. Any flavor’s label showing less than 300 mg of caffeine per serving (which is still listed in the product description text) is for a different product, not the “Ultimate” versions being sold. Some flavors have a correct label, they list 300mg caffeine per serving (most people take less at once) and the other included stimulants. I only noticed because I came here to read it since it’s dark text on dark background in the container and hard to read irl. I don’t know whythey switched out the correct label for some flavors here sometime in the last seven days.

This is very helpful in providing extra energy and I have lost weight since using it. I have included it as a permanent addition. Lol The taste of these are all awful, but I like this icy blue razz the best. The mango has the strongest taste of whatever it is that's awful. I only use this once each day as it has creatine in it which if too much is taken can cause more fluid weight gains than quality weight. I did experiment with 2x per day as is recommended in the instructions, as you should too. Thank you.

Cellucor C4 has been a great product for me for a long time. I like the mix of ingredients as well as their dosages. The caffeine is not too strong and the other ingredients keep it from making me anxious. It's pure energy without the anxiousness or the annoying tingling that come from other products with high levels of carnosyn/beta alanine. I started with a half scoop, and after a month use a full scoop. The taste is good, and it mixes really well in a shaker bottle. The price is reasonable compared to other products in it's class.

Too intense for me but my son loves it.

Used to get this all the time in stores. Best price is here. Gets you going for a workout.

Great product. It gives me energy

I just purchased 2 of these and one is only half full and the other is three quarters full. I do not understand why two of the same product contain different amounts for the same money. I think one is definitely short of the intended amount of the product. I have not opened either of them and just received them today.

This is my favorite pre-workout product. It tastes good and definitely does the job. I’ve bought several times and will continue to buy.

One of the best pre-workout,
