What I Like
What I Don't
Straight talk before anything else: this is a recon, not a review. I do not have a case of these in hand yet. What follows is a coach's read of the published label, and the full review lands once I have lived with it for a while.
One housekeeping note. If you knew this can as C4 Energy or C4 Original, same product, new name. It is now sold as C4 Performance Energy.
The Label Read
Each 16oz can carries 200mg of caffeine, zero sugar, and no artificial colors, plus vitamin B12. That caffeine number is roughly two cups of coffee in one can, so treat it like a real dose, because it is one.
The label also lists CarnoSyn beta-alanine and BetaPower betaine, which are legitimate branded ingredients. Here is the honest catch: C4 does not publish the milligram doses for either one on the product page. Without a number, I cannot tell you whether you are getting a working dose or a sprinkle for the label. So I will not pretend to know. The tingle test will have to wait for the full review.
Now the part that actually made this can worth a recon page. It is NSF Certified for Sport, and that is C4's own on-page claim, in their words: "Tested and certified for professional and collegiate athletes." That is the same third-party certification I lean on when I put my athletes on Thorne. In a category famous for mystery blends, an energy drink that submits to independent testing is rare, and a drug-tested athlete finally has something to point to when someone asks what is in their cooler.
Who It Is For
I keep my supplement advice in two lanes. My drug-tested athletes and the health-basics lane stay on Thorne, creatine first, and my read on that is in the Thorne creatine review. Flavored performance products like this one are the gym-bag lane: the stuff that makes training and long dad days more tolerable. This can is gym-bag lane with a certification most of that lane never bothers to earn.
If you are the guy grabbing a random energy drink before the gym or the 6am youth practice you volunteered to coach, this is the version of that habit with a paper trail. If caffeine wrecks your sleep, or you were planning to drink it at 4pm, skip it.
The Honest Math
The 12-pack runs $27.99, about $2.33 a can, or $25.19 if you subscribe. Singles at the register run $3 to $4 for drinks with no testing behind them. Eleven standard flavors, though three were out of stock when I wrote this. Get it, and check back for the full report once I have run a case through real weeks.

After Action Report
On paper, this is the rare energy drink a drug-tested athlete can point to a certification on: NSF Certified for Sport, 200mg caffeine, zero sugar, about $2.33 a can. That is the recon read. The full review lands once I have lived with a case.
