Pretty good.
I got this product about 2 and a half weeks ago, and so far so good. Definitely gives you a good pump and more energy. However, the taste isnâ??t that good, when u mix it, there are usually chunks at the bottom, and the â??light tingling sensationâ?? is more of an annoying itching sensation. But still, does what itâ??s mean to do pretty well.

C4 Gains of the Gods
It's the best pre workout on the market. It's the only one that I can take at 5am and get me through a whole work out. Gains for days baby.

Too much caffeine!
Got this in my Pro Box and took it at 5:00 am for a 5:30 workout. Couldn't tell if my lifts improved, but I did feel as if my heart was going to burst out of my chest periodically for the next eight hours and even had trouble staying asleep come 9:00 pm. My results may not be typical since I hadn't had caffeine for several years prior to C4, but even so, you can get all the key ingredients in bulk for much cheaper than this and make your own preworkout. I suppose this could provide a nice kick in the pants for those that need extra motivation to get to the gym each day, but for those with the discipline to go no matter what, look elsewhere for your creatine, beta alanine, citrulline, etc.
