Could be better
Not very powerful. Strong taste. Gets the job done to the bare minimum but does the job. Only filled a quarter of the way don’t let the size fool you.

1/2 empty pkg
No issues with product itself but seems like container got bigger and fill amount is less. Deceptive packaging when compared to competitive products. Will give some other products a try now
1 reply from customer care team - 7 months ago
Hello! Thank you for your review. When we produce our products at manufacturing facilities, the containers are filled to near capacity at the point of production. Due to the nature of powder products in general, settling will occur as the air escapes, leaving the product in a more compact state. The transit of the product can also compact the powder further. As an example, the scoop is the last item to go into the container, yet it is often found in the middle of the bottom. That just goes to show the amount of movement and compacting that occurs after production. The difference between the actual capacity of a container and the volume of a product is called slack fill. As a company, we abide strictly with regulations pertaining to this, and we always reassure customers that their products are packaged by weight, not volume. Rest assured, the product you've purchased will have the number of servings within as advertised on the outside of the package.

Good energy boost
[This review was collected as part of a promotion.] Seems to be a good energy boost before working out.Self admittedly, i'm not good about remembering to take it.So i'm sure that it would work better if I used it, as i'm supposed to.

Great for energy before workout
[This review was collected as part of a promotion.] I received this from Influenster in exchange for my review. This pre workout energizes me before working out and helps me get a more intense workout in. Also has nice sweet taste.

Solid pre-workout
[This review was collected as part of a promotion.] Good pre-workout if you like the blue raspberry flavor (I generally do). I found it to be a little too overpowering, but nothing I can’t fix. It mixed well with water and gave me a nice little boost. I don’t think there’s anything particularly special or different about this than other products, though. But it works well if you want to try it!

Not the worst, not the best
[This review was collected as part of a promotion.] So overall, I found this preworkout fairly average. The ingredients and amounts were suboptimally dosed and the flavor although drinkable was not the best, and for the lack of some serious ingredients in there, I expected a better taste. I probably would not buy this if I had a chance and opt for something with different ingredients and dosing for what I want, but it’s not bad for someone who just wants an extra kick in their workout.

Sweet,.but yummy
[This review was collected as part of a promotion.] This stuff has an amazing flavor, but was a little on the sweet side. I am not sure how effective jt was, as I didn't feel anything after drinking it.

The artificial taste might be off putting, but still gives you a good boost of energy
[This review was collected as part of a promotion.] I’m not a big preworkout powder user, however, my husband is and tried this out. His main thoughts were, it gave him a good boost of energy, the taste isn’t too desirable but it’s not disgusting, the powder dissolves well in water. The main complaint he had about the taste was the fact he isn’t a big fan of the blue raspberry taste. I did try it a little bit, and i thought the flavor was good.

Must try pre workout
[This review was collected as part of a promotion.] Easy to mix, great tasting pre workout. Great formula of ingredients to give energy for your workout! Blue razz flavoring was not too over powering.

Fav flavor!
[This review was collected as part of a promotion.] Love this flavor! This gives the energy that I need pre workout. I wish the scoop was smaller so it could easily mix into a water bottle but other than that it’s a great pre workout!

Good
[This review was collected as part of a promotion.] We definitely liked the flavor of this one. It mixed well without being too gritty. It will give you a good jolt of energy (it has 200mg of caffeine) so be careful taking it with other caffeine during the day

Good flavor and stable energy
[This review was collected as part of a promotion.] This flavor is really good. It is so easy to prepare for a pre workout because it mixes so easy. This gives me a gradual energy boost. The first time I took it if gave me a horrible itch on my face and neck but the next few times it didn’t give me that reaction.

Gives you extra hydration, muscle endurance, great flavor with zero sugar and caffeine to keep you going strong through a workout. The packaging is easy to use with a twist off lid and it’s easy to scoop out. It tasted pretty good and also comes in different flavors.

Can’t go wrong- great pre-workout!
[This review was collected as part of a promotion.] this is the first pre-workout I’ve ever tried and honestly it makes so much better than I thought it would. My brother has been taking this brand for ages, and he loves and swears by it so I fully understand why!

Skip the new formula. It does't even feel like C9 anymore
New product is not good. The old blue raspberry was the BEST. The new formula hardly tastes of blueberry at all and tastes more artificial and sugary. I don’t mind the drink being less blue, I’m guessing there’s less blue coloring used and that’s nice. However there’s hardly a hint of blueberry in the new flavor, it tastes nasty and I’m upset they degraded it so much. It’s a whole 360 from the old flavor. Was a core staple to my work outs, now I have to find a new pre-workout

Boost of energy and hydration needed for a workout!
[This review was collected as part of a promotion.] This pre-workout is great! It definitely gives you that boost of energy and hydration you need for a workout. It mixes in water super easily and tastes super good. I also noticed in the ingredients that it’s colored with spirulina extract so it’s natural instead of artificial color which is really cool!
