Awesome product. If you need a strong and  reliable preworkout, this is a good option. I’ve had several tubs of it and haven’t been disappointed.*

Added C4 Extreme to my pre-workout rotation. I love all things Lemon flavored so Lemon Drop did not disappoint. Good flavor! It gives me the energy I need after a long day at work and sitting in traffic. No crash afterwards. One of my go-to pre-workouts for sure!*

It’s not too bad whatsoever. I️ don’t take preworkout everyday of the week... sort of depends on what shift I’m work and what I’m training but my body is used to being fueled with Mr Hyde and although this doesn’t quite pack the punch compared to I️t I️ don’t have anything negative to say about I️t. I️t works well, give the energy boost needed and I️ even sip on a scoop sometimes during the day to keep myself going *

Very nice taste, sweet, looks beautiful, but the effect is not to strong.. maybe a bit soft. It's my first time that I use pre workouts, however, I put 1 scoop and haven't feel any difference between that and a cup of strong coffee.*

He is a good commodity. But 50 Servings are prone to moisture. It is recommended to buy 30 Servings. Used before training, there is a very powerful help. If you need help. Buying him is a good choice. Just the taste I'm not used to.*

C4 50x worked for me pretty well in the gym but the flavor was not something I enjoyed. I normally look forward to taking my pre-workout and going to the gym, but the flavor of the C4 50x made taking it more of a chore versus a reward. I've never had the original C4 so I don't know if the flavor is any better with the original.*

I have been taking C4 extreme for a couple weeks and I have noticed a little difference. I take one scoop and it gives me a little boost. If you want a good kick take two scoops. This stuff mixes well and taste great! When use a scoop & a half if gives me a decent kick so that I can have a good pump.  You won't get that tingle feeling but your body will get a warm sensation. Not bad for the price! *
