How much energy and stimulant power does this provide?

C4 Ultimate supplies 300 mg of caffeine per serving, a level intended to significantly increase alertness and drive during workouts. The product also includes a patented compound to help manage tolerance buildup, allowing consistent stimulant support when used responsibly.

• 300 mg caffeine per serving for strong pre-workout stimulation
• Patented compound included to support prolonged caffeine effectiveness
• Zero sugar formulation to avoid added calories from sweeteners

What ingredients support muscle pumps and circulation?

The formula features a Super Citrulline Pump Matrix that promotes nitric oxide pathways linked to increased blood flow and muscle fullness. Combined with other supporting ingredients, it’s intended to enhance the feeling of pumps during resistance or high-intensity training.

• 6 g Citrulline-based pump matrix for improved blood flow
• Additional vasodilatory cofactors to amplify pump sensations
• Served in a palatable Strawberry Watermelon flavor for easier consumption

Does this help reduce fatigue and extend performance?

C4 Ultimate contains clinically studied CarnoSyn beta-alanine to support muscular endurance and delay the onset of fatigue during high-rep sets or sustained efforts. When combined with the caffeine and pump ingredients, it’s formulated to help you maintain intensity through longer training intervals.

• 3.2 g CarnoSyn beta-alanine to support endurance under load
• Synergy with caffeine for sustained training focus and output
• Zero sugar to avoid energy crashes associated with simple carbs

How should I use this product safely and effectively?

Mix one scoop with water and consume 20–30 minutes before training, or follow the label instructions. Because of the high caffeine level, start with a partial serving if you’re sensitive to stimulants and avoid combining with other caffeine sources.

• Single serving timing: 20–30 minutes before exercise
• Start with half a scoop if sensitive to stimulants
• Avoid additional caffeine and follow recommended daily limits

Who is this for: C4 Ultimate Zero Sugar in Strawberry Watermelon is best suited for experienced gym-goers, athletes, and fitness enthusiasts seeking a potent, all-in-one pre-workout that emphasizes energy, pumps, and endurance without added sugar.
