The observed listing says it is tested, but names no lab or certifier.
A testing badge without an issuer or report is a marketing claim, not evidence. Ask for the lab name and lot-specific report.
Creatine dose matches the studied range
This shows whether the label amount lines up with the cited study context, if that amount is actually present. It is not a dosing recommendation.

Only product facts and comparisons earn a card. Pipeline gaps stay collapsed.
Is the label honest?
Checks outNIH / published research
Creatine dose matches the studied range
The panel declares 5 g creatine per serving, at the top of the commonly studied 3–5 g/day range. This compares declared label numbers with research; it does not verify contents or recommend an amount.

Every declared ingredient has an amount · 6 quantified rows.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Why it mattersYou can compare each declared dose with research instead of guessing what is hidden inside a blend.

The observed listing claims third-party testing without naming a lab or certifier. No product-bound report or matching NSF product entry is retained, so the claim cannot be verified as stated.

Read the ingredient evidence directly
These links provide the public research context used alongside the captured panel. They do not establish safety, effectiveness, or product quality.
What would settle the biggest open question?
Can the testing claim be tied to a named laboratory and this product lot? Evidence that would settle it: lot-specific COA naming the laboratory and matching the product lot.

Confirmed evidence
What checked out02
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Creatine dose matches the studied range
The panel declares 5 g creatine per serving, at the top of the commonly studied 3–5 g/day range. This compares declared label numbers with research; it does not verify contents or recommend an amount.
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.
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, ISSN position stand on creatine (PubMed).
Unresolved public record
What is still missing07
We looked for these signals but could not settle them from public sources. A gap is not a strike.
“Lab tested” claimed, but no lab or report named
The observed listing claims third-party testing without naming a lab or certifier. No product-bound report or matching NSF product entry is retained, so the claim cannot be verified as stated.
Listed amounts fit the serving
Technical check only: the panel’s 5 actives sum to 8,880 mg, which fits inside the ≈11,000 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 × 11 g = 330 g, matching the printed net weight 330 g (NET WT. 11.6 oz (330 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, magnesium 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 — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
No recall found — which is not the same as being tested
This means only that no enforcement record matched the brand name — it does not mean the product was tested, reviewed, or cleared by FDA. New and untested products also have no recall records.
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 2026-07-23 to 0 on 2026-07-23 (net +0). 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 5 g listing number equals CREATINE 5 g + MAGNESIUM 40 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.
2
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
3
Which specific study supports this claim — and was it run on this exact formula?
Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.
4
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
5
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.
6
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
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
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.
