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.
The 175 mg caffeine claim matches the panel
We did the comparison: the listing claims 175 mg of caffeine, and the listing-image panel shows 175 mg caffeine 10g (about 1 scoop). Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Creatine Monohydrate | 3.3 g | — | |
| Beta-Alanine | 1.6 g | — | |
| Micronized L-Citrulline | 750 mg | — | |
| L-Tyrosine | 385 mg | — | |
| Caffeine | 175 mg | — | |
| Calories | 10 | — | |
| Total Carbohydrate | 3 g | — | |
| Vitamin D (as Cholecalciferol) | 12.5 mcg | — | |
| Thiamin (as Thiamin Hydrochloride) | 2 mg | — | |
| Niacin | 20 mg | — | |
| Vitamin B6 (as Pyridoxine HCI) | 2 mg | — | |
| Folate | 340 mcg DFE | — | |
| Vitamin B12 (as Cyanocobalamin) | 10 mcg | — | |
| Pantothenic Acid (as D-Calcium Pantothenate) | 10 mg | — | |
| Calcium | 50 mg | — | |
| Sodium | 20 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “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; any remaining comparison concerns the front-label framing.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
How it’s marketed doesn’t match how it was studied
The listing uses “pre-workout” framing, but published research attributes creatine monohydrate’s effect to studied as a daily supplement — the effect comes from muscle saturation over weeks, not from timing a dose before a workout. Sources: NIH ODS — Exercise & Athletic Performance fact sheet, Creatine stability by moisture and temperature (PubMed).
Each ingredient’s 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.
Registered in NIH's supplement label database (DSLD)
Label #308430 “Platinum Pre- Fruit Punch” (Optimum Nutrition), entered 2024-06-20, with the full Supplement Facts on file — see the panel below. Company on file: Manufacturer — Optimum Nutrition, Aurora, IL.
UPC independently corroborated
Open Food Facts resolves 748927052695 to "GOLD STANDARD PRE-WORKOUT" (OPTIMUM NUTRITION) — consistent with this listing.
No physical impossibility in the listed amounts
Technical check only: the panel’s 13 actives sum to 6,294 mg, which fits inside the ≈10,000 mg serving. This means the numbers are physically possible — it does not mean the formula was validated or the contents confirmed.
Photo-read pack math is internally consistent
30 servings × 10 g = 300 g, matching the printed net weight 300 g (NET WT 10.58 OZ (300 G)). This checks agreement within the photo read; it is not an independent contents test.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Lyons Magnus, Inc recalled a different or not-exactly-bound product on 2022-07-22: “Findings and potential for Cronobacter sakazakii and Clostridium botulinum.” (status: Terminated). The recalled product was: “Optimum Nutrition Gold Standard 100% Whey Chocolate 11 fl oz (325mL). UPC 7 48927-06409 4. Shake well. Best when served chilled. Manufactured for Optimum Nutrition, Inc., 350” — not necessarily the product on this page. Verify at FDA’s recall database.
180-day review-count history is on file
Exact-listing history records written-review counts from 1,540 on 2026-02-05 to 1,533 on 2026-07-04 (net -7). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…t Punch flavor This pre-workout powder helps support performance, energy and focus when taken con…” | 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 — see Related research below. 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?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Creatine Monohydrate | shaded = doses used in studies (3 g–5 g) · bar = this label | 3.3 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.
Verifiability profile — 4 of 6 public signals

Where it sells
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store optimumnutrition.com: 55 supplement products (+2 merch items) — for comparison, single-focus brands typically carry 5–30 products; very broad catalogs are common among companies that rebrand ready-made formulas — a pattern note, not a verdict.

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.

ℹ Use pattern in research: studied as a daily supplement — the effect comes from muscle saturation over weeks, not from timing a dose before a workout.
⚠ Consistency note: the listing markets “pre-workout” framing, but published research attributes this ingredient's effect to sustained daily use — the marketing frame and the research mechanism don't line up.
