Overview

C4 Extreme aims to improve exercise performance through a combination of ingredients such as caffeine, beta-alanine, creatine nitrate, and arginine AKG. While caffeine provides energy and some ingredients have research supporting their ergogenic effects, the proprietary blend makes it difficult to evaluate the specific dosages and effectiveness of other ingredients, limiting the certainty of its performance benefits.

The Good

Contains caffeine, which has proven ergogenic effects

Includes beta-alanine, which has potential to improve muscular endurance

Includes creatine nitrate, which may improve power output

The Bad

Potential for jitters and anxiety due to caffeine content

May cause paresthesia (tingling) from beta-alanine

Contains an 'Explosive Energy Blend' which is a proprietary blend making it difficult to assess the dosage of individual ingredients

Is it for you?

Best For: Athletes, fitness enthusiasts, individuals seeking energy and focus for workouts

Skip If: Sensitive to caffeine, pregnant or nursing, have heart conditions, or are under 18
