C4 Ultimate is a zero-sugar pre-workout in Icy Blue Razz, formulated to support workout energy, pumps, muscular endurance and focus with 300 mg of caffeine and a 6 g Citrulline Pump Matrix.
For training sessions when energy, concentration and workout performance are priorities, C4 Ultimate combines caffeine with ingredients selected for pump support and muscular endurance. The Icy Blue Razz flavor gives this formula a distinct flavor option, while its ingredient blend is designed for more than a caffeine boost alone.
C4 Ultimate is made to support energy, pumps, performance and focus during workouts. Its Super Citrulline Pump Matrix is formulated to support an increase in nitric oxide and workout pumps. CarnoSyn beta-alanine is a clinically studied ingredient formulated to support muscular endurance and help fight fatigue.
The formula includes a patented, clinically studied compound that may help the body prolong its caffeine tolerance buildup. This is a qualified support claim, not a promise that caffeine tolerance will not develop. The formula also contains 300 mg of caffeine to provide workout energy.
This C4 Ultimate formula is Icy Blue Razz and provides 20 servings. It contains zero sugar, so the flavor and serving count are clear considerations when choosing this pre-workout. Packaging may vary.
