Does the marketing hold up?

Every ingredient shows its amount · 6 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Marketing claims, checked

The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed3

“USA FACILITY — Every batch third-party tested for purity and”

A testing body is named on the brand page (NSF), but we found no lot-specific certificate of analysis.

Evidence →
“USA FACILITY — Every batch third-party tested for purity and”

“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

Evidence →
“sustained energy, immune health & muscle recovery for men and”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

Every ingredient shows its real amount — nothing is hidden in a proprietary 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.

CheckedCan you trust the review pattern?

Reviews rose from 2 to 22 between July 23, 2025 and July 7, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 2 to 22 between July 23, 2025 and July 7, 2026. The largest rise inside any single 30-day window was about 6, so the count moved in steps rather than in one burst.

  • We have not found a public label filing for this exact product.

Research behind the findings

Dose and research context

The label amount is shown beside the range used in the linked ingredient studies.

Dose vs research

Magnesium

25 mg per serving — below the 200–420 mg/day used in the linked studies.

Background reading

What the research says about these amounts

Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.

The panel lists 25 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.

0studied 200 mg–420 mg

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

The panel lists 11 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
