Pre-Workout
C4 Original - Rainbow Blast
What it is
C4 Original by Cellucor is one of the world's most popular pre-workouts and a great choice for beginners, with a moderate 150mg of caffeine per serving plus beta-alanine (for that signature tingle) and creatine nitrate to support performance. It gives a noticeable energy and focus boost without being overwhelming. This tub in Rainbow Blast provides about 30 servings. Contains caffeine; Avoid taking it late in the day or if you are sensitive to stimulants.
Rainbow Blast is the sweetest C4 flavour we carry, fun if you like sweets and cloying if you do not.
Who it's for
Anyone swapping energy drinks for something purpose-built for training, at a caffeine level they can repeat several times a week.
How to use it
Mix one scoop with water 20 to 30 minutes before training.
Worth knowing
Contains caffeine, so not for under-18s, pregnancy or breastfeeding, the stimulant-sensitive, or anyone with heart or blood-pressure concerns.
Our take
If your current pre-workout is a can of energy drink, this is a straightforward upgrade. A moderate 150mg of caffeine, plus beta-alanine and creatine nitrate aimed at the session rather than just the buzz. It will not feel dramatic, and that is rather the point, because C4 is built to be usable every session rather than saved for special ones.
