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.
Cost per serving matters most: JYM Supplement Science Pre JYM
$1.67 against $1.83 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: JYM Supplement Science Pre JYM Plus Pre-Workout
3 of 4 main actives on JYM Supplement Science Pre JYM Plus Pre-Workout 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.

The same fields the FormulaSignal API and MCP server return for this pair.
| Field | Pre JYM | Pre JYM Plus |
|---|---|---|
| Caffeine per serving The Record's total across every declared caffeine source. Neither direction is better. | 300 mg | 300 mg |
| Price per serving Observed package price divided by the stated serving count. The basis of each price is on the product's Record. | $1.67 | $1.83 |
| Monthly cost at five uses a week | $36.18 | $39.65 |
| Servings per container | 30 | 30 |
| Ingredients with a disclosed amount A proprietary blend total counts as one amount, and the split inside it stays undisclosed. | 18 of 18 | 14 of 14 |
| Main actives inside researched doses Declared amounts measured against the range the cited research used. Not a measure of effectiveness. | 2 of 3 | 3 of 4 |
| Documented cautions | Stimulant-load gate | Stimulant-load gate |
| Regulatory records A filing exists. It is not a finding about safety. | None on file | Huperzine A |

| Label observed | October 24, 2026 | August 3, 2026 |
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.

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 JYM Supplement Science Pre JYM Plus Pre-Workout's label as JYM Supplement Science published it, observed August 3, 2026.
- Matched 19 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; 3 of 4 on JYM Supplement Science Pre JYM Plus Pre-Workout.
- 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.
