Both are super effective when I need a pick me up for the gym after a long day! You get the tingles from the beta-alanine but it isn’t too strong like I thought it might be since it’s “extreme”. It was good clean energy and I felt like I could work out longer and harder than I otherwise would. The cherry limeade flavor was decent, but it had a chemical taste to it. The Strawberry Kiwi was very good and I also tried the Lemon Drop however that flavor is not available for review. Overall great product!

The energy from this preworkout was amazing. It wasn't too strong where you crash after your workout, but it definitely hits you hard. The only downside would probably be the flavors. they have an underlying kind of chemical, "preworkouty" taste to them still. Tingles weren't too bad, but I almost prefer them because you know the preworkout is working. Definitely one of the more stronger ones out there.

Cherry Limeade - I'm not a big fan of cherry-flavor anything so I am pretty bias in my perspective of this flavor, but it actually tasted decent to me (a bonafide cherry hater). It was smooth to drink... smooth consistent taste... not overly acidic like some I have tasted in the past. Strawberry Kiwi - This flavor was on point! They mixed well together as flavor combo and you could actually taste kiwi individually as well as strawberry. Aside from watermelon this is probably one of my favorite flavors from Cellucor. Overall - Smooth taste... no acidic after-bite... good strong pump and alertness... I'm a believer!

This is a really strong preworkout. The name says it all, extreme! With 300 mg of caffeine, you are pretty much guaranteed some explosive energy. If you are sensitive to stimulants then I would go for the regular C4 because this may be a little much. This really helps me after a long day at work. I take me a scoop and then I am ready to hit the gym! This keeps my energy up the entire session with no crash.

I was able to try these two flavors and the only real concern I had was I felt like they could use a little more flavor. The flavor was there but not quite as strong as in other variations. Now dont get me wrong, it is VERY POSSIBLE that I was using too much water and thinning it out. The boost of energy that it gave me definitely lived up to it's name, extreme! I have been feeling more tired than usual lately (gotta love season change) and this helps me get back up and get moving. I have used it as preworkout and for anytime energy. I was not disappointed at all by the effectiveness!

I was lucky enough to try out 2 different flavors of C4 Extreme Energy recently, and it did not disappoint! This product does what it is advertised to do, gives you extreme energy! The ingredient list here is excellent as usual per all Cellucor products, with this pre-workout having 300mg of caffeine, 3.2g of beta-alanine, 1g of arginine and a very nice energy blend. As a side note, I really find the chart on the side of the bottle useful, showing you exactly what each C4 pre-workout powder is intended to do, obviously here Extreme Energy being best used for energy, but still having a good effect on pump and focus as well. I also like the amount of caffeine here, being 300mg which in my opinion is the perfect amount. Not too much but not too little either, perfect enough to really get you going without going too crazy on the caffeine. The two flavors were great! Cherry limeade was amazing! One of the better I've had, and strawberry kiwi was great as well! Overall, this is a great pre-workout if you are looking for some great flavors along with a nice rush of energy!

SOLID pre-workout! I absolutely love how it doesn't clump up (like other brands) isn't a mess to scoop and the taste! I used one scoop each with around 8oz of water and sipped on it while en-route to the gym (20 mins) The flavors of each were spot on, along with energy! I train around 5am so energy is a must-have for me. I was able to obtain a gnarly pump during chest and back, all while feeling like there was no stopping me! Fantastic job Cellucor!

I have used C4 Extreme Energy for a few weeks and really enjoy it. It's a step up from the regular C4 as it has 300mg of caffeine. It gives a really good energy and focus boost. Not much for a pump, which I normally don't get any pumps from pre-workouts. Flavoring is on point like all Cellucor products. I'd recommend this to anyone who responds well to 250-300mg of caffeine in their pre-workout.

Great pumps, tons of energy. Icy blue razz in my opinion is best flavor and mixes really well. It does clump if your not careful where you store it so I don’t recommend leaving in gym bag but even with the clumps I just grab a couple and drop in water night before and let it dissolve by next day good to go.

C4 flavor testing was superb!!! Flavors are amazing, I used a serving scoop in about 8oz of water mixed with crushed ice. I am a huge fan of Cellucors C4 line and this doesn't fail me too the least. C4 mixes well with products from Cellucor but be careful to read the ingredients because too much isn't good. Mixability: 10/10 - No issues at all, no extra flakes give it a good shake or vortex spin and you're good to go. Overall: First off thank you Cellucor for making another excellent product, C4 products work tremendously. Not even that the flavor is a great starting point as well as it tastes amazing. But we are all here for the gainz and getting the boost necessary and routines in, I give this product a thumbs up!!! More Extras: ATP is a source of energy our body created, the more ATP the more our body can do. I won't be going into complete detail as I have learned all about ATP, energy systems, etc in College however one thing I found great about the C4 is that you won't feel any crash after training/workout. I felt the boost and noticed my training/workout lasted longer than normal. I could've gone even more, and it's hard to find a naturally perfect balance of ingredients in an energy booster, not only does it boost ATP/Energy within the body, the ingredients are a perfect mixture, plus no crash which is what we all need

It's okay but I think I like the C4 Ripped better still.
