Cellucor C4 Ultimate x WWE Pre Workout Powder Nectarine Guava Knockout - Sugar Free Preworkout Energy Supplement for Men & Women - 300mg Caffeine + 3.2g Beta Alanine + Patented Creatines - 20 Servings

I really enjoyed the C4 brand. I liked this product but unfortunately they are out of it often and the price has increased significantly. The only stomach discomfort comes from overindulgence of the product so if you use it responsibly then you should be fine unless you are sensitive to these things and some people may have to work up to the ultimate level. I like the quality of the product and seems to be pretty reliable. It is easy to use and tastes great. All you need to do is mix it into room temperature water after you remove some and shake. You can then make it cold if you would like but it does require you to shake again intermittently. I didn't notice an increase in nail strength and if anything I may say it decreased it because I do notice my nails breaking once in a while but that could be from my line of work. If the price is right I say grab some and try it because I think it is my preferred brand if I didn't take price into consideration.

Excellent

Good taste, decent energy.

Normally I'm not a big fan of c4, as other options just have more kick. This powdered version has what the canned c4 lacks though, it's a top notch pre-workout. Even if you're not a fan of the cans, try the powder.

love it
