Price — ON Saves $0.32
Optimum Nutrition Gold Standard is $21.60 vs C4 Sport at $21.92. The difference is only 32 cents over the whole tub.
That's less than a penny per serving. For most buyers, price won't be the deciding factor unless every dollar counts.
Caffeine per Serving — ON Shows Its Hand
ON lists 175 mg of caffeine clearly on the label. C4 Sport does not disclose its caffeine content, which may worry caffeine-sensitive users.
If you track your caffeine intake closely, ON gives you certainty. C4's undisclosed dose could be higher or lower — you won't know until you try.
Servings per Container — Equal
Both tubs contain 30 servings. A month of daily use for most lifters. No advantage either way.
Rating — Both at 4.5 Stars
Both products hold a 4.5-star average across thousands of reviews. Buyers for both are satisfied with the performance.
Neither product disappoints based on user feedback. The tie means you should pick on features, not rating.
Number of Reviews — C4 Has More Data
C4 Sport has 20,329 reviews vs ON's 16,929. That's 3,400 more opinions backing it up.
More reviews mean a more reliable rating. Both are well-reviewed, but C4 has a slight edge in sample size.
Certifications — C4 Is NSF Certified
C4 Sport is NSF Certified for Sport, a program recognized by USADA, MLB, and NHL. ON has no third-party certification listed.
For athletes subject to drug testing, C4's certification is a must-have. It guarantees no banned substances and accurate labeling.
Value — ON Wins by a Penny
ON costs $0.72 per serving vs C4's $0.73. A one-cent difference is negligible — both are excellent values.
When factoring the coupon, C4 may actually be cheaper. The live coupon (check product page) can tip the balance.
Best For — Different Strengths
C4 is built for endurance with beta-alanine to fight fatigue. ON is built for energy with a clean caffeine boost.
Choose C4 if you push through high-rep sets or cardio. Choose ON if you need a pre-workout that wakes you up fast.
Flavor Options — C4 Offers Variety
C4 Sport comes in Blue Raspberry, Fruit Punch, and Watermelon. ON is limited to Blueberry Lemonade.
If you get bored of flavors easily, C4 has more choices. ON's single flavor is nice but you might want to rotate.
