Original Pre Workout, 150mg Caffeine, Icy Blue Razz, 30 Servings

C4 Original Pre-Workout in Icy Blue Razz has become one of my favorite pre-workout supplements. The flavor is refreshing without being overly sweet, and since it's sugar-free, it fits well into my nutrition goals. The 150mg of caffeine provides a smooth energy boost that helps me stay focused and motivated throughout my workouts without feeling overly jittery. I also noticed improved endurance during training, and the beta-alanine gives that familiar tingling sensation that lets me know it's kicking in. It mixes easily with water, doesn't leave clumps, and the 60-serving container offers excellent value. Overall, this is a reliable pre-workout that delivers consistent energy, great taste, and solid performance. I'd definitely recommend it to anyone looking for an effective, zero-sugar pre-workout.

I’ve been using the Icy Blue Razz flavor, and overall it’s a solid pre-workout. The taste is good, it’s sweet but not overpowering and easy to drink before a workout. In terms of performance it gives a noticeable boost in energy and focus without feeling too overwhelming. The beta-alanine does cause that typical tingling sensation, but that’s expected and fades once you get moving. I’ve found it helps with endurance and pushing through longer workouts, especially on heavier training days. It mixes well without clumping and I haven’t had any issues with digestion. The caffeine level feels balanced and not too strong, but enough to get you going. I think that this is a reliable pre-workout that’s good energy, solid focus, and a flavor that’s easy to stick with long term. It’s a good value for the price.

As an avid weightlifter, I've tried numerous pre-workout formulas, but C4 Blue Raspberry has quickly become one of my favorites. The moment I opened the tub, I was greeted by a refreshing aroma that hinted at the delicious flavor to come. Mixing it up is a breeze; it dissolves well in water without any gritty residue. The taste is fantastic—sweet and tangy, just like a nostalgic blue raspberry candy. It’s definitely a treat to sip on before hitting the gym. In terms of performance, C4 delivers. I felt a noticeable boost in my energy levels and focus during my workouts. The explosive energy helped me power through my heavy lifts and maintain intensity throughout my sessions. I appreciate the blend of ingredients that not only gives me a kick but also helps with endurance, allowing me to push through those last few reps. What I also love is that I don’t experience any jitters or crashes afterward, which can be a concern with some pre-workouts. Instead, I feel energized and ready for the rest of my day. Overall, C4 Blue Raspberry has become an essential part of my pre-workout ritual. If you’re serious about your lifting and looking for a tasty and effective boost, I highly recommend giving it a try!

I've taken all sorts of pre-works out for many years. Jack3d was probably my favorite before they changed it to the garbage that it is now. They all have some type of problem as you end up adding more and more because you build up a tolerance to it. Get a burst of energy then crash afterwards. This is the first time I tried C4. My friend actually recommended it. I got watermelon. First thing in tasting it I said wow, this tastes EXACTLY like watermelon Jolly Ranchers!! The biggest thing I can say with this, is it does not give you some epic rush that you then come crashing down. I take this 30 minutes before working out and then I have a solid hour of intense lifting. Afterwards I still have energy. It's actually nice, almost throughout the entire day I don't feel tired or just destroyed. I plan on trying all the flavors once I run out just to see which is best. But so far I really like this pre-work out. Very easy to drink/mix. Does not give any stomach pains or squirts. There's nothing worse than taking a pre-work out before legs and coming to the horrifying realization mid squat that something is brewing down there about to explode. EDIT: First flavor tried Watermellow = Tastes Great. Second flavor tried: Icy Blue Razz = Tastes EVEN Better! I love it!

Absolutely love it! The flavor is perfect and not gritty at all (I just mix in a cup with my straw). It gives me so much energy for workouts. I was nervous about taking it but I don’t get jitters from it. Highly recommend if you’re a beginner who needs a boost

I was never really one for any sort of pre workout drinks until a couple friends of mine who lift regularly recommended this stuff. It was a bit skeptical but I noticed a remarkable difference on just my first workout. I usually try to lift for 45 min to an hour and usually around the half hour mark start to feel like little tired and start checking my clock wondering how much more time I have. Well after taking c4 the first time and working out I checked my clock when I started to feel a bit tired and it had already been an hour! I even felt like I still had the energy to keep going but I decided not to push myself. This has since become a regular part of my work out and I am able to maintain momentum and energy for a full hour every time. This stuff definitely works when it comes to giving you that extra boost for a workout. Downsides: I went with the default icey blue razz flavor and its definitely not the most pleasant tasting thing in the world. Not horrible by any means but definitely not the type of thing you sip slowly and enjoy. The only other downside is the tingly sensation this can sometimes give. I notice its more intense if you hadn't eaten much but at times this product can cause a harmless tingling sensation over your body, and particularly in your limbs. It goes away once you start moving/working out but it can be a bit uncomfortable and alarming at first. Though again, its harmless and doesn't happen to everybody. Overall I would recommend this product, it definitely ads a boost to your workout and helps you go that extra mile

I enjoy this product and so does my girlfriend. When I first gave it to my her, she had no clue it was one of my supplements bcz of how awesome it tastes. Now, I can’t get her to stop drinking it lol. Has an amazing taste that doesn’t even taste like any sort of supplement. Tastes like strawberry lemonade 🍋. I drink this first thing in the morning and I do feel the difference in how it energizes me and I think a bit clearer as well. This is shocking bcz I do suffer from brain fog so this is an amazing plus..especially to ditch coffee and just go wihh to this water based drink. Nice for the summer especially, as it’s a light beverage but I drink this all year around. I add a splash of lemon and it taste a little tropical (especially when ice cold). Very versatile product that is easy and effortless to consume bcz it’s tasty and doesn’t have the “healthy/nasty” taste associated with it. Potential lifetime customer here! Oh, and a LITTLE goes a long way too. Very budget friendly and a good bang for your buck.

This is the first pre-workout I’ve ever tried! I have the blue razz flavor, and it tastes terrific!! It’s sweet, almost like candy. However, there’s a decent bit of chalkiness to this formula. It’s like it never fully dissolves or mixes, no matter how much you shake it up. C4 is very affordable compared to Ghost’s pre-workout (which I’m dying to try), so I can get past the chalkiness for the price tag, but it’s definitely a little off-putting. I found I had mild jitters my first day using this, but after my second day & so on, I was fine. It absolutely helps me focus during my workouts and gives me so much more stamina… it’s very noticeable the difference this has made in my workout performance. So for that, this is a great beginners pre-workout!! I do recommend it. It gets the job done & has a great flavor! I have read from in-depth online reviews that C4 has 100mg less caffeine than Ghost’s pre-workout, & C4 is supposedly not fully transparent about all of their ingredients. In addition, I do wish they could improve the formula to get rid of the chalky texture, so for that I’m giving them 3 stars.
