Every ingredient amount is disclosed
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

How to read this report
What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
Panel, decoded
What the label discloses
1listed rows
1separately quantified
0combined blend totals
The listing-image panel publishes an amount for each of its 1 listed row. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Creatine Monohydrate | 5 g | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; the open question is whether those listed amounts are independently verified and how they compare with relevant research.
vision:claude-cli:subscription Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
What checked out3
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Barcode confirmed in an outside database
Open Food Facts resolves 048107252922 to "Creatine Monohydrate" (GNC Pro Performance) — consistent with this listing.
The review count moved gradually, not in one burst
Written reviews rose from 0 to 14 between August 15, 2025 and July 21, 2026. The largest rise inside any single 30-day window was about 1, so the count moved in steps rather than in one burst.
Documented concerns
What needs caution0
These are documented contradictions or claims that need more evidence. They are separate from missing data.
No contradictions or product-specific cautions were found at this check depth.
Unresolved public record
What is still missing8
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing doesn't publish enough to check the math
The saved listing evidence does not establish net weight, unit count, per-serving dose, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.
Multiple USPTO brand-owner records are shown
USPTO returned multiple live supplement-class records for the exact brand wordmark: General Nutrition Investment Company, GNC Holdings, LLC. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Photo-read pack math is internally consistent
100 servings × 5.1 g = 510 g, matching the printed net weight 500 g (NET WT. 18 OZ (1.12 LB) 500 G). This checks agreement within the photo read; it is not an independent contents test.
Research context is available for the listed ingredients
Published sources describe how creatine monohydrate have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH ODS — Exercise & Athletic Performance fact sheet, Creatine stability by moisture and temperature (PubMed).
FDA recall appears in this brand's history
This recall is not about the product on this page. GNC Holdings LLC recalled a different product on April 25, 2025. FDA has since closed that case. The recalled item was “GNC Women's 30+ Vitapak, Carton of 30 Sachets. Each sachet contains four tablets and a capsule. Paper-board carton that measures 10.25 width x 3.56 height x 3.15 depth containi”. FDA recorded the reason as “Undeclared Fish allergen (parvalbumin)”. Verify at FDA’s recall database.
Public label filing not saved
We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
180-day review-count history is on file
Exact-listing history records written-review counts from 0 on 2025-08-15 to 14 on 2026-07-21 (net +14). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?
Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
1
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
2
Scan the barcode on the package and confirm it reads 048107252922.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
3
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
What the listing promises — claim by claim
Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…Exercise Support: Get more reps, improve muscle stamina and endurance, and have more effective workouts with creatine when combined with progressive resistance training*” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed. |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.
This label vs. the doses studied
Why is this shown?
An ingredient can be well-studied at one amount and barely studied at the amount in your bottle. This lines the label up against the doses researchers actually used. It answers ‘are these the same numbers?’ — never ‘should you take this?’
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Creatine Monohydrate | shaded = doses used in studies (3 g–5 g) · bar = this label | 5 g — within the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.

Ingredient science — creatine monohydrate · Grade A
- Evidence: Human RCT meta-analyses (5+ indexed in PubMed for strength outcomes; ISSN position stand). PMID 40265319 · PMID 37144634 · PMID 39545789
- Studied serving: 3–5 g/day maintenance (≈0.03 g/kg); optional loading 20 g/day split ×4 for 5–7 days.
- Absorption: Creatine monohydrate is ~99% orally bioavailable when delivered intact — absorption is not the limiting factor; delivery-medium stability is.
- Delivery medium: Creatine is stable as a DRY powder but hydrolyzes toward creatinine (inactive) in warm, moist, or acidic media. A gummy is an aqueous, often acidic matrix — the documented reason independent testing finds many creatine gummies far below label.
- Kidney disease: consult a clinician before use.; Pregnancy/lactation: safety not established at supplemental doses.; Combine with adequate hydration.
