Which fits you

Choose by what you care about.

Each line is a measured difference between the two labels, not a verdict. Nothing here says either product works, or is safe for you.

  • You want less caffeine per serving: Six Star Pro Nutrition Pre-Workout Explosion 2.0

    160 mg against 200 mg declared per serving. Less is not safer and more is not better; how much suits you is a question for a clinician.

  • Cost per serving matters most: Six Star Pro Nutrition Pre-Workout Explosion 2.0

    $0.60 against $1.17 a serving at the prices FormulaSignal observed (Aug 3, 2026). Not every price here is established as a list price.

  • You want creatine in the same scoop: Cellucor C4 Original

    Cellucor C4 Original declares Creatine Nitrate (as NO3-T) at 1 g; Six Star Pro Nutrition Pre-Workout Explosion 2.0's complete label declares no creatine.

  • You want more of the main actives at researched doses: Six Star Pro Nutrition Pre-Workout Explosion 2.0

    1 of 4 main actives on Six Star Pro Nutrition Pre-Workout Explosion 2.0 sit inside the dose range the cited research used, against 1 of 5 on Cellucor C4 Original. A comparison of numbers, not of how well either works.
