Not the best pre I've had. Finished my tub of C4 Ultimate and made the mistake of trying this Extreme Energy next....I found that Extreme Energy left me with lower focus. There is no Citulline Malate in this formula either, had to add 6g of it myself for a good, long-lasting pump. Flavor was good- As most of the C4 formulas are. I think I'll stay away from this one for now...

I was a huge fan of the og extreme energy, glad to see they brought it back with a vengence. This stuff well lives up to it's name! 300mg caffeine tends to be my sweet spot on most days. I was a tad hesitant to pull the trigger on this due to the Rauwolfia as I usually have adverse side effects from poor sourcing that other companies like to use. I am glad I got some because there were no adverse reactions, just insane pumps, energy, and focus! I see quite a few 50 serving tubs being stocked in my cabinet in the near future.

Had the opportunity to try Icy Blue Razz and Cherry Limeade C4 Extreme. First let me mention I am a pretty high stim junkie and this stuff was able to deliver! I definitely felt a sudden surge of energy so be warned if you dont tolerate stims well, if you do - this is your guy. The Cherry Limeade flavor was pretty good, a little chalky. Definitely better than Blue Razz if we are being honest. Pumps were solid and the added TeaCrine is something I love about the C4 products. Focus is 10/10 on this stuff - carried over to work as well after my lunch gym sessions. Awesome stuff.

The C4 Extreme Energy formula delivers 3.2 grams of beta-alanine, 1 gram creatine nitrate, 1 gram AAKG, and 841 mg of a C4 Extreme Energy Blend. The draw of the product basically rests on this 841 mg proprietary blend which is led off by NALT and followed by 300 mg of caffeine anhydrous. I like that the blend is rounded out with velvet bean, theacrine, rauwolfia, and Huperzine A. I wish I knew the exact dosing of each of these stims to comment on expected effects. However, this energy and focus blend looks respectable and really should give quite the kick, especially for users newer to pre-workouts. I tried the C4 Extreme Energy cherry limeade and blue razz. The solubility of the powder was good in 6 oz of water. The cherry limeade flavor is great. It has a nice balance of sweet and tart. The flavor isn't very evocative of cherry or lime and seems some generically fruity, but it is a very good flavor. In comparison to the cherry limeade, the blue raspberry flavor is a little less exciting. It is essentially identical to any other C4 blue raspberry flavor you have had. The flavor is not too sweet or sour, kind of finds a middle road between the two. It is very strongly colored and will leave your tongue blue for a little. I think it is a solid 8 of 10 flavor. In terms of effects, the energy hit quickly and with a moderate intensity. The beta-alanine tingles were incredibly strong for me; I've been accustomed to 1 to 2 gram doses of BA versus 3.2, which likely explains the very strong tingles. My focus was elevated modestly. My workout started off very well. My warm up cardio was awesome, and then I transitioned into some upper body lifts that went well. After that I started to get a little bit chilly and experienced some minor weakness. I think sometime the combination of nitrates, caffeine, and rauwolfia can have that effect on me sometime. It wasn't that big of an issue as I still finished up my workout well. It also didn't start happening until about an hour in. Ultimately, I was pretty happen with C4 Extreme Energy's effects. Energy - 9/10 Focus - 8/10 Performance - 9/10 Overall: 9/10 Flavor - 10/10 Side Effects: Tingles and chills Recommend? Yes

As far as the effects go, I'll say that the Beta Alanine tingles started shortly after I took this, which you can credit to the whopping 3.2g of Beta Alanine. My endurance was defininitely heightened, and I had some great results on my heavier compound lifts. Beyond what I am typically accustomed to in terms of mental focus and pumps, I can't say that I noticed any dramatic improvement in those departments, but then again the name of this product is extreme energy and that's what it delivers. My energy was through the roof. As far as taste, I thought the cherry limeade flavor was very good, but a little lime-heavy for my preference, I was hoping the cherry flavor would be more prominent. But that's a pretty minor point, just something I thought I'd point out. Icy Blue Razz is always great!
