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 (Oct 20, 2026 and Oct 4, 2026). Not every price here is established as a list price.
You want more of the main actives at researched doses: Kaged Pre-Workout (Pre-Kaged)
2 of 2 main actives on Kaged Pre-Workout (Pre-Kaged) sit inside the dose range the cited research used, against 2 of 3 on JYM Supplement Science Pre JYM. A comparison of numbers, not of how well either works.

Ingredient by ingredient
What both declare, and what only one does.
Matched by FormulaSignal's normalized identity, so two brand names for the same compound line up and two forms of one ingredient do not. Vitamins, minerals and electrolytes are left out; caffeine is compared as a total above.

Which label?
Which label is a number from?
A figure without a date may describe a label that is no longer sold.
Kaged Pre-Workout (Pre-Kaged): FormulaSignal could not read Kaged's product page at its last check. That is a fact about the page, not a finding that the product was discontinued.
Method
How this page was made.
What FormulaSignal did
- Read JYM Supplement Science Pre JYM's label as JYM Supplement Science published it, observed October 24, 2026.
- Read Kaged Pre-Workout (Pre-Kaged)'s label as Kaged published it, observed August 3, 2026.
- Matched 26 declared active ingredients by normalized identity, so two brand names for one compound line up.
- Checked each main active's declared dose against the range the cited research used: 2 of 3 on JYM Supplement Science Pre JYM; 2 of 2 on Kaged Pre-Workout (Pre-Kaged).
- Looked for confirmed formula changes on either product: 0 on file, each reviewed against two dated sources.
What it did not do
- No taste test and no lab test. Every figure is what a label or a brand's own page declares, not what was measured in a tub.
- No score and no winner. Differences are measured and shown; nothing is rated.
- No payment and no preview. No brand paid to appear, and none saw this page before it was published.
- No health advice. Whether an ingredient or an amount suits you is a question for a clinician.
