C4 Original Carbonated by Cellucor
Twelve cans, twelve workouts. This is a pre workout drink you drink cold straight from the can, without a shaker and without a scoop. Each 500 ml can contains 160 mg caffeine, zero sugar and zero carbohydrates. Intended for athletes who want something half an hour before their session that is already prepared, fits in the gym bag and can be opened anywhere.
What makes a can different from powder
The difference lies mainly in behaviour, not in chemistry. Powder has to be measured out, dissolved and carried along in a shaker that you then have to rinse out again. A ready-to-drink pre workout skips that entire step. You pull open the can and you are done. On the other hand, you cannot adjust the dosage: it contains exactly what it contains, the same every time. For anyone keeping an eye on their caffeine intake, that is an advantage rather than a limitation. In terms of absorption, a pre workout drink is barely inferior to powder in water. In liquid form caffeine no longer has to dissolve, so the only thing determining the speed is how quickly your stomach empties. With a calorie-free, carbonated drink that happens quickly.
160 mg caffeine per can, in perspective
The can states 32 mg per 100 ml. Across 500 ml that comes down to 160 mg, roughly as much as one and a half cups of strong filter coffee. EFSA applies 400 mg per day for adults as the safe upper limit and 200 mg as the limit for a single intake. One can stays neatly below that, but add coffee, tea or a gel and the daily total mounts up quickly. Good to know: caffeine has a half-life of four to six hours. If you train in the evening, there is still a considerable amount left in your blood at midnight. Many people wonder whether they can drink two on a heavy day. In short: you can, but you are then above the EFSA guideline for a single intake and your sleep pays the bill.
What else is in the can
Besides caffeine, the European formula contains L-arginine and taurine, both at 0.21 percent, which comes down to just over a gram per can. Betaine is included under the brand name BetaPower. Be honest about this: those amounts are below what you come across in studies, so caffeine does most of the work in this can. What is present at a legally established amount are the two B vitamins. Per can you get 7.5 mg niacin (47% of the reference intake) and 1.25 micrograms of vitamin B12 (50%). Niacin contributes to the reduction of tiredness and fatigue. Vitamin B12 contributes to a normal energy-yielding metabolism. Good to know if you are familiar with the American version: the European formula is shorter and contains exactly the substances listed above.
Frozen Bombsicle in plain terms
Frozen Bombsicle is the flavour of a blue ice lolly: fresh, slightly sour and distinctly sweet, without the syrupy feel of a powdered drink. The carbonation makes it more of a soft drink than a supplement, and that is exactly why many people find this format more pleasant. Drink it well chilled and spread it over ten to fifteen minutes. Five hundred millilitres of carbonated liquid right before squats or intervals sits heavily on the stomach for some people. And because you are buying a tray of twelve, this is also the flavour you drink twelve times in a row.
All in all, this is a pre workout drink for convenience: one can, a fixed caffeine dose and nothing to weigh out or clean. Anyone who prefers to adjust dosages themselves, or who wants specific substances at study-level amounts, is better off with loose powder.
