C4 Protein is a powder from Cellucor for anyone looking for a focus and energy boost before their workout. There are 3 flavors to choose from – from Hershey's Milk Chocolate to Vanilla Bean.

What exactly is a pre-workout booster?

Pre-workout boosters are mixtures that are consumed before training. Typical ingredients: caffeine in various dosages, beta-alanine (responsible for the well-known, harmless skin tingling), citrulline and arginine, as well as focus ingredients such as tyrosine. The formulations vary widely – from moderately dosed beginner products to highly dosed formulas for experienced users. In addition, there are pump boosters, which completely do without stimulants and can therefore also be used for evening workouts. For beginners, the proven rule applies: test tolerance with half a serving and keep an eye on your total caffeine intake.
