Legion Pulse vs Cellucor C4
C4 is the best-selling pre-workout in the world. On the ingredient it is sold for, it gives you one eighth of the dose the research used. Here are both labels.
This one is not close, and the numbers are printed on both tubs. C4 gives 1 g of citrulline where the trials used 6 to 8 g. Pulse gives 8 g. C4 is cheaper, and that is the only category it wins.
The labels, side by side
| Legion Pulse | Cellucor C4 Original | What trials used | |
|---|---|---|---|
| Citrulline malate | 8 g | 1 g | 6-8 g |
| Beta-alanine | 3.6 g | 1.6 g | 3.2 g daily |
| Caffeine | 350 mg | 150 mg | 3-6 mg/kg |
| Label | Every dose disclosed | Partly blended | - |
| Verdict | Fully dosed | Under-dosed | - |
Where the competitor wins
C4 is cheaper per serving and it is easier to find — it sits on the shelf of every supermarket and gym in the country. At 150 mg of caffeine it is also the gentler option if you are stimulant-sensitive, and for a lot of people the caffeine is the only part they actually feel.

Where Legion wins
Every active in Pulse sits at or near the dose used in the research, and the label prints all of them. On citrulline, the ingredient a pre-workout is sold for, it delivers eight times what C4 does. If you are buying a pre-workout for anything beyond the caffeine, that is the difference you are paying for.
The eight-times gap
The trials on citrulline malate used 6 to 8 g per serving. C4 Original gives you 1 g. That is not a rounding difference or a formulation preference — it is a dose that the research would not have detected an effect at. The number is printed on the tub, in the panel almost nobody turns around to read.
Why beta-alanine is a red herring in both
Beta-alanine works by saturating muscle carnosine, which takes weeks of daily dosing. A pre-workout taken on training days only under-delivers it by design, no matter which one you buy. The tingle it causes feels like the product working, which is exactly why it appears in almost every pre-workout on the market.
What you are actually paying for
If caffeine is all you want, caffeine pills cost a few cents a dose and both of these are poor value. The case for a full formula is the citrulline and the betaine on top, and only one of these two actually carries them at a dose the research supports.
Who each one is for
- You want the cheapest option on the shelf
- 150 mg of caffeine is enough for you
- You are buying it mostly for the caffeine
- You want the actives at the researched dose
- You read labels and want every number printed
- 350 mg of caffeine suits you
