C4 Performance Pre-Workout

What it is.

C4 is one of the better-known pre-workouts because it prints every dose on the label rather than hiding them in a proprietary blend. One serving contains 160 mg of caffeine, 6 g of citrulline malate and 1.6 g of beta-alanine. That is a moderate stimulant dose — meaningful, but not the extreme end of the market.

A fully disclosed pre-workout formula with 160 mg of caffeine per serving, plus citrulline and beta-alanine.

Key features

• 160 mg of caffeine per serving — moderate, not extreme
• 6 g of citrulline malate and 1.6 g of beta-alanine per scoop
• Every ingredient listed with its per-serving amount
• No proprietary blend
• Ten grams of amino acids per serving

Who it's for

• Strength and conditioning sessions
• Training late in the day (with caution on timing)
• People who want a disclosed formula rather than a blend
