Product Overview

The C4® family has been pioneering, building, and perfecting pre-workouts longer than some brands have been in sports nutrition. Since its launch in 2016, C4® Ultimate has delivered energy you can feel, powerful pumps, muscular endurance, extreme focus, and peak performance in every scoop.

C4® Ultimate is a call to action. It's a challenge, beckoning you to break records, crush your goals, and make the most of every workout. The question is: Are you up to that challenge?

Key Ingredients

C4® Ultimate features the cutting-edge performance ingredient: 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.*

Supports Your Goals

C4® Ultimate packs 300mg Caffeine, 3.2g CarnoSyn® Beta-Alanine, 4g L-Citrulline, 2g Creatine Performance Complex, 1g Citrulline Malate, 1g NitraMax (NO3-C)™, 1g Creatine Nitrate (NO3-T)™, and other performance ingredients to support your fitness journey.

C4® Ultimate can be consumed 20-30 minutes before your training session to support extra reps, sets, and minutes spent in the gym for maximum gains.

Good To Know

For those less sensitive to stimulants, the average individual can expect to feel the full effects within 45 minutes and last for 3-6 hours. For those more sensitive to stimulants, the effects will likely be felt faster and last closer to 6 hours.

Do not get cotton candy, it tastes nothing like it. I've used cellucor C4 before and have had good flavors, but cotton candy is horrible.

The flavor isn't that great, the pump is mild, and the focus is almost non-existent. Overall it's fine; I won't be rebuying it, though.

אני השתמשתי וזה מוצר מעולה ומרגישים את ההבדל באימון בעיה שלו הקפאין שלא נותן לך לישון אני מעדיף לתאמן בבוקר שלא ישפיע הקפאין בלילה
