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: Kaged Pre-Workout (Pre-Kaged)
274 mg against 300 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: JYM Supplement Science Pre JYM
$1.67 against $2.25 a serving at the prices FormulaSignal observed (Aug 3, 2026). Not every price here is established as a list price.

2 of 2 main actives on Kaged Pre-Workout (Pre-Kaged) sit inside the dose range the cited research used, against 2 of 4 on JYM Supplement Science Pre JYM. A comparison of numbers, not of how well either works.
