We've been pioneering, building, and perfecting pre-workouts longer than some brands have been in sports nutrition. For nearly a decade, the C4® family has led the category with explosive energy and performance, the best flavors, clinically studied ingredients, and cutting-edge formulas.*
We're obsessed with research, improvement, and results. We're innovators and leaders. We have a legacy of building the best pre-workouts on the market, because that's precisely what we want to take. All our obsession comes together in C4® Ultimate Project Clear Evolution. Ultimate delivers energy you can feel, powerful pumps, muscular endurance, extreme focus, and peak performance.*
Since its launch in 2016, C4® Ultimate has defined what it means to be the industry's best pre-workout, delivering unrivalled energy, focus, pumps, and performance. To lead the pack and remain the best, the best don't rest—they evolve. This is the evolution of C4® Ultimate.*
The new generation of Ultimate delivers enhanced training benefits on every level, includes new performance ingredients for even stronger pump power, and joins the ranks of Project Clear Evolution.*
Every product built on the Project Clear Evolution platform is founded on three core pillars:
Clean: No artificial dyes. No artificial flavors.
Clear: Fully transparent labels. No proprietary blends.
As our Clean, Clear, and Evolved pre-workout powerhouse, C4® Ultimate is free from artificial flavors and dyes, made with a fully disclosed formula, and upgraded with cutting-edge performance ingredients like NitraMax (NO3-C)™ Citrulline Nitrate and a double dose of pump-boosting nitrates.*
FEATURING NITRAMAX (NO3-C™) Created by bonding citrulline with patented nitrates, NitraMax (NO3-C) is an advanced compound that delivers dual-pathway nitric oxide (NO) support. Unlike citrulline or citrulline malate, which work through a single mechanism, NitraMax™ supports two mechanisms of NO creation, the arginine pathway (eNOS) and the nitrate-nitrite conversion system, to help promote the ultimate pump.*
INSIDE EACH SCOOP
CAFFEINE ANHYDROUS (300MG PER SERVING) Caffeine is a well-studied stimulant that has numerous energy, performance, and even thermogenic benefits. The amount of caffeine in C4® Ultimate has been clinically shown to support an increase in power output and aerobic exercise capacity.*
THEACRINE (62.5MG PER SERVING AS TEACRINE® 40%) TeaCrine® is a patented and clinically studied novel ingredient that helps support an extended energy experience. Studies also suggest that the body doesn't adapt to TeaCrine as quickly as it does to caffeine, therefore prolonging tolerance buildup.*
RAUWOLFIA VOMITORIA (1MG PER SERVING) Don't let the seeming small dose fool you. A strong stimulant potentiator, rauwolfia unlocks ultimate energy when paired with caffeine. Buckle up.*
CARNOSYN® BETA-ALANINE (3.2G PER SERVING) Every serving of C4® Ultimate delivers 3.2 grams of patented CarnoSyn® Beta-Alanine to fight fatigue and support muscular endurance. (Note: Beta-alanine can sometimes produce a harmless skin-tingling sensation. Take it as a sign that it's time to move some serious iron.)*
CREATINE PERFORMANCE COMPLEX (2G PER SERVING) Creatine HCL (1g Per Serving as patented CON-CRET® ) Creatine hydrochloride is a patented, clinically studied, and highly absorbable form of creatine. Creatine supports ATP production, muscular size, and strength.*
CREATINE NITRATE (1G PER SERVING) A university-studied form of creatine that's formed by bonding creatine with nitrate anions. On the individual level, creatine and nitrate are powerhouse performance elements. When fused together, they create an unstoppable bond to support strength, power, and pumps.*
CITRULLINE PERFORMANCE COMPLEX (6G PER SERVING)
L-Citrulline (4g Per Serving) Pure L-citrulline signals the body to increase arginine production, which then converts to nitric oxide to power your pumps. This dose is roughly equivalent eight grams of citrulline malate.*
Citrulline Malate (1g Per Serving) A precursor to arginine and nitric oxide production, citrulline malate further promotes an increase in nitric oxide levels.*
Citrulline Nitrate (1g Per Serving as NitraMax (NO3-C)™) Our exclusive dual-pathway nitric oxide amplifier is formulated with patented nitrates to support nitric oxide through two distinct mechanisms. Take all the citrulline listed in this blend, boost it with additional nitrates, and you've got Ultimate pump support.*
TAURINE (1G PER SERVING) Helps support mental performance when paired with caffeine.*
N-ACETYL-L-TYROSINE (400MG PER SERVING) A more soluble form of L-tyrosine, NALT plays a role in supporting mental and cognitive health during stressful activities like physical training.* ALPHASIZE A-GPC (200MG PER SERVING) A patented and clinically studied form of choline, AlphaSize® may support increased focus, which can contribute to a strong mind-muscle connection in the gym.*
HUPERZINE A (50MCG PER SERVING) Huperzine A is a nootropic ingredient that supports memory, learning, and concentration.*
SCIENTIFICALLY STUDIED, PATENTED INGREDIENTS No matter how big the scoop size or how revolutionary it claims to be, a great pre-workout starts with best-in-class ingredients used in effective doses. Since ingredients are not created equal, patented ingredients are important for multiple reasons, particularly because they're backed by quality manufacturers who rigorously test and research their products for efficacy and safety.
Patented ingredients are the best in their categories, or they're so novel that they're complete category-creators. We're proud to say that C4® Ultimate contains six patented ingredients from leading ingredient companies of the highest caliber.
