FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
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 Nu…
Locked evidence record →Open the full source-linked findingChecks outIs the label honest?
Every declared ingredient has an amount · 16 quantified rows.
You can compare each declared dose with research instead of guessing what is hidden inside a blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

The barcode identity checks out · 748927052695.
The outside identifier points to this product, so the other checks are less likely to be about a look-alike.
Evidence and sources
Open Food Facts resolves 748927052695 to "GOLD STANDARD PRE-WORKOUT" (OPTIMUM NUTRITION) — consistent with this listing.

The candidate page's review pool may differ from the observed listing. Because the page does not publish a matching UPC/GTIN, LookCloser does not attribute that review aggregate to this exact sellable unit.
Prices and stock are point-in-time observations. Candidate pages are never used as product evidence. No affiliate links; LookCloser earns nothing from these sellers.

Confirmed evidence
What checked out03
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Full label filed with NIH — ingredients on public record
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.
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.
Barcode confirmed in an outside database
Open Food Facts resolves 748927052695 to "GOLD STANDARD PRE-WORKOUT" (OPTIMUM NUTRITION) — consistent with this listing.
Documented concerns
What needs caution01
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Marketed differently from 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).
Unresolved public record
What is still missing05
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Listed amounts fit the serving
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.
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 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.
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
Answered by the panel: the 0.175 g listing number equals Caffeine 175 mg + Thiamin (as Thiamin Hydrochloride) 2 mg. What lot-specific document confirms those declared amounts?
The panel resolves what the headline number includes. The remaining question is whether the product in hand matches those declared amounts; ask for a lot-specific certificate of analysis.
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 748927052695.
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.
