CLEAN, CLEAR, EVOLVED

Introducing Project Clear Evolution: our mission to set a higher standard. To elevate the entire C4® family—and beyond—by pioneering the next generation of premium performance supplements that exceed your expectations.*

• Evolved: Innovative ingredients. Enhanced formulas.

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.*

KEY INGREDIENTS:

Ultimate Energy:

• Caffeine Anhydrous, 300mg - 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 as Teacrine® 40% - TeaCrine® is a patented and clinically studied novel ingredient that helps support an extended energy experience. Studies suggest that the body doesn't adapt to TeaCrine as quickly as it does to caffeine, therefore prolonging tolerance buildup.*
• Rauwolfia Vomitoria, 1mg - A strong stimulant potentiator, rauwolfia unlocks ultimate energy when paired with caffeine.*

Ultimate Performance:

• Carnosym® Beta-Alanine, 3.2g - Every serving of C4® Ultimate delivers 3.2 grams of patented CarnoSyn® Beta-Alanine to fight fatigue and support muscular endurance.*
• Creatine HCL as CON-CRET®, 1g - Creatine hydrochloride is a patented, clinically studied, and highly absorbable form of creatine. Creatine supports ATP production, muscular size, and strength.*
• Creatine Nitrate, 1g - A university-studied form of creatine that's formed by mixing creatine with nitrate anions. Creatine and nitrate are powerhouse performance elements. When fused together, they create an unstoppable bond to support strength, power, and pumps.*

Ultimate Nitric Oxide:

• L-Citrulline, 4g - 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 - A precursor to arginine and nitric oxide production, citrulline malate further promotes an increase in nitric oxide levels.*
• Citrulline Nitrate as NitraMax (NO3-C)™, 1g - 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.*

Ultimate Focus:

• Taurine, 1g - Helps support mental performance when paired with caffeine.*
• N-Acetyl-L-Tyrosine, 400mg - 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 - 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 - Huperzine A is a nootropic ingredient that supports memory, learning, and concentration.*
