C4 Original is a pre-workout made by Cellucor. It is designed to boost energy, raise muscular endurance, heighten focus and increase motivation during exercise.
The pre-workout contains caffeine, which Cellucor states could “support an increase in energy”. It also contains beta-alanine (under the Carnosyn brand name) to improve endurance. Meanwhile, creatine nitrate is described as an “advanced form” of creatine, which is said to boost muscle energy.
C4 Original also contains N-acetyl-L-tyrosine (NALT), which is said to improve focus and reduce stress. In addition, arginine is included to help enhance muscle pumps.
The product is – or has been – available in several flavors. These include “Frozen Bombsicle”, “Pink Lemonade” and “Icy Blue Razz”.
