How to Read a Proprietary Blend, Using the Jelly Force Panel
Quick answer
A proprietary blend prints one weight for several ingredients. On this panel that weight is 82 mg and nine ingredients share it. Only caffeine carries its own number, 5 mg. Label order runs descending by weight, so four names sit above 5 mg and four sit at or below it. Everything else is unpublished.
What a proprietary blend is
One line, one number, several ingredients. That is the whole idea, and the whole problem.
A proprietary blend is a group of ingredients printed as one line with one weight. The panel names the members and gives no amount for any of them.
Makers give two reasons: recipe secrecy, and flexibility, since the split can shift between runs without a label change. Either way you learn the size of the group, not the parts.
- 82 mgTotal blend weight per gummy
- 9Ingredients inside that total
- 1Ingredient with a printed amount
- 8Amounts left unpublished
Why one total is legal
Federal labeling rules allow it. A maker may name the blend, print the combined weight, and list the ingredients underneath without individual figures.
One requirement comes with that permission. The names must appear in descending order of weight, heaviest first. That single rule is what makes a blend partly readable. Nothing requires an extract ratio or a test result, so those are not published.

† No Daily Value has been set for this blend. It comes to 82 mg per gummy, and the label adds that this is equivalent to approximately 567 mg of dry powders, as the label puts it. Eight of the nine ingredients inside it carry no figure of their own. Other ingredients listed on the wrap: Corn syrup, cane sugar, water, apple pectin, sorbitol liquid, natural flavors, citric acid, sodium citrate dihydrate. Allergen statement: not published.
Four nutrition rows sit above one blend row, and that blend row is the whole active side of this product.
Caffeine is broken out at 5 mg. It is the only amount inside the blend a reader does not have to infer.
Label order is the only clue you get
The nine names run muira puama extract, maca extract, catuaba extract, green tea extract, caffeine, ashwagandha, L-arginine, Tribulus terrestris, horny goat weed extract.
Caffeine sits fifth. Under descending order, everything above it weighs at least 5 mg and everything below it weighs 5 mg or less.
That splits the blend into two halves a reader can reason about.
- The blend is 82 mg, so 77 mg sits outside the printed caffeine.
- The four names below caffeine hold 5 mg or less each, so at most 20 mg together.
- That leaves the top four holding at least 57 mg of the 77 mg.
The ceiling and the floor, position by position
| Position on the panel | Amount printed | What the order allows |
|---|---|---|
| 1. Muira puama extract | None printed | Largest share: at least about 14 mg, at most about 62 mg. |
| 2. Maca extract | None printed | 5 mg or more, and no larger than muira puama. |
| 3. Catuaba extract | None printed | 5 mg or more, and no larger than maca. |
| 4. Green tea extract | None printed | 5 mg or more. It carries caffeine of its own, uncounted. |
| 5. Caffeine | 5 mg | The printed figure. Every bound here depends on it. |
| 6. Ashwagandha | None printed | 5 mg or less. |
| 7. L-Arginine | None printed | 5 mg or less. |
| 8. Tribulus terrestris | None printed | 5 mg or less. |
| 9. Horny goat weed extract | None printed | 5 mg or less, and the smallest of the nine. |
The muira puama floor comes from the top four sharing at least 57 mg, so the largest holds at least a quarter of that. The ceiling comes from the other three extracts needing 5 mg each.
These are bounds, not amounts, and they assume the order rule was followed.
Checking 82 mg against studied amounts
A total means little on its own. Set beside the amounts research has used, it starts to say something, and that comparison needs no knowledge of the split.
| Ingredient | What the panel allows | What published sources describe |
|---|---|---|
| L-Arginine | 5 mg or less | Used by the body to make nitric oxide. Published work on exercise uses grams a day (NIH ODS). |
| Caffeine | 5 mg, printed | FDA's general figure for healthy adults is about 400 mg a day, and coffee holds roughly twenty times 5 mg (FDA, 2024). |
| Maca extract | 5 mg or more | A systematic review found the evidence for sexual function too limited to judge (Shin et al., 2010). |
| Green tea extract | 5 mg or more | Concentrated extracts are linked to rare liver injury, and green tea interacts with nadolol (NCCIH, 2025). |
| Ashwagandha | 5 mg or less | Data run two to four months, rare liver injury is reported, and thyroid medicine may interact (NCCIH, 2023). |
| Tribulus terrestris | 5 mg or less | A U.S. Defense Department review found no strong evidence for performance claims (Operation et al., 2024). |
| Muira puama, catuaba, horny goat weed | Three of the nine | Little human research and no federal fact sheet, so there is no studied amount to compare against. |
L-arginine is the clearest case. Studies work in grams a day, and label order caps it at 5 mg here. None of the linked work tested this gummy.
The 567 mg equivalence line
The bottle prints "82 MG Per Serving" and, below that, "equivalent to approximately 567 mg of dry powders". Both numbers are real. They measure different things.
The 82 mg is what sits in the gummy. The 567 mg describes the raw dried plant material behind the extracts before they were concentrated.
An extract exists to shrink plant material. Saying it came from more material describes the process, not a larger amount.
- The ratio behind each extract line, which is what reversing 567 mg would need.
- How much of the 567 mg belongs to any single plant.
Questions to put to a seller
Ask for the split in writing
Request the milligram amount of each ingredient. A seller who has it can send it.
Ask for the extract ratio on every extract line
Several names end in "extract". Each needs a ratio before research means anything.
Ask which laboratory tested your lot
Ask for the certificate with assay results attached, not the reference number alone. Here the codes are lot JEL-26/JE-8318 and CoA JEL-8318-26-JE.
Ask whether the finished product has been studied
Research on separate ingredients is not research on a blend.
Ask for the allergen statement
Allergen statement: not published on this label. Free-from seals on product images are claims, not a declared allergen line.
Ask where the authorized route is
FDA keeps finding hidden prescription drugs in men's products sold online (FDA, 2026).
Send them by email so the answers arrive in writing. Website questions go to [email protected], Mon-Fri 9:00am-5:00pm ET. Order questions go to +1 (302) 200-3480.
What a blend label can never settle
For the panel line by line, read the Supplement Facts page. For what each ingredient is, read the ingredients page.
Erection or drive problems can signal heart disease or diabetes. A doctor is the right first stop, not a blend row.
Proprietary blends: the questions readers send
Is a proprietary blend allowed to hide amounts?
Yes. Federal rules let a maker group ingredients under a blend name and print one combined weight. The names inside must run in descending order of weight.
Does a blend mean the product is low quality?
Not by itself. It means the amounts cannot be checked, so the product is judged on the total, the name order and whatever the seller confirms in writing.
Why does only caffeine have a number?
Caffeine is the one ingredient here with its own figure, 5 mg. A printed number inside a blend does double duty: it gives one real amount, and it fixes bounds for the names around it.
What is the largest any single ingredient here could be?
Muira puama extract is listed first, so it holds the biggest share. Three other extracts sit above the 5 mg of caffeine, which puts muira puama at roughly 14 mg to 62 mg of the 82 mg.
Does "equivalent to approximately 567 mg of dry powders" raise the amount?
No. It describes the raw dried plant material behind the extracts before extraction. The gummy holds 82 mg of blend. The larger figure is a manufacturing comparison.
Can the amounts be worked out from the 567 mg figure?
No. That needs the extract ratio for each extract line, and none is published. Without a ratio the equivalence line cannot be turned back into milligrams.
What should I ask a seller about a blend?
Ask for the amount of each ingredient, the extract ratio behind every extract line, and the assay on the certificate for your lot.
Where do the blend figures on this page come from?
From the bottle wrap, which prints 82 mg, the nine names and the 5 mg of caffeine. The bounds shown here are arithmetic, and they are labelled as arithmetic.
