Cellucor C4 Ultimate
C4 Ultimate is the strongest tub in the C4 range — the step up for people who have been taking C4 Original for a while and no longer feel much from it.
Higher caffeine, higher doses of the performance ingredients, and a formula built for the heaviest sessions rather than everyday use.
Why choose it
- The strongest pre-workout in the C4 range
- Higher caffeine and higher performance doses than C4 Original
- Built for heavy, high-volume training
- 380g tub
- Lemon Twist and Tutti Frutti
How to use
Not a starting point — use C4 Original first if you are new to pre-workout. Start with half a scoop to assess tolerance, mix with 300–400ml of cold water 20–30 minutes before training, and avoid within six hours of bedtime.
Contains a high level of caffeine. Not suitable for children, or people sensitive to caffeine, pregnant or breastfeeding.
