What a recheck covers

Requests bring a source check forward. They do not scan your tub, guarantee a result, or start a subscription. Requests for the same product share a monitoring pass. Allowances reset monthly in UTC; guest allowances are shared by people on the same connection.

Under review means a newer source finding is open. Until review settles it, the formula below stays the one on the label dated August 3, 2026. Candidate findings are not public Signals.

Historical timeline

Comparable formula states.

Dates below are observation dates. They are not exact reformulation dates.

Historical formula evidence is not yet sufficient for a reliable comparison. This does not establish that the product never changed.

Confirmed Signals

Reviewed changes in the public Record.

No confirmed public Signal is associated with this product. This is not a claim that the product never changed.

Research-dose context

Selected evidence, not a universal effective dose.

These comparisons retain the studied protocol, source, and limitations. They do not establish safety, effectiveness, or a dose recommendation for this product.

Caffeine

Product declaration: Total caffeine from all declared sources: 125 mg
Selected studied range: 140 to 420 mg
Protocol and duration: 2 to 6 mg per kg body mass, 15 to 60 minutes before exercise, shown here for a 70 kg adult
Studied context: Studied for endurance-type aerobic exercise (moderate to large ergogenic effect, most consistent evidence category per ISSN 2021), muscular endurance and movement velocity in resistance exercise (small to moderate effects), sprinting/jumping/throwing (2-7% improvements), and cognitive attention/vigilance under fatigue. NIH ODS notes it "might enhance performance in endurance-type activities... And intermittent, long-duration activities."
Limitations: Minimal effective dose remains unclear. Repeated-sprint performance benefit is inconsistent and the ISSN position stand says this "requires further research." Effects of habitual/chronic caffeine use on the ergogenic response are described as equivocal.

Cautions and regulatory records

A filing and a documented risk are not the same thing.

These attach to declared ingredients, not to this product as a whole. Nothing here establishes that the product is safe or unsafe. Talk with a qualified health professional.

No documented caution is recorded against the declared ingredients on this Record. That is not a finding that the product is safe.

Where the sources disagree

What we could not read cleanly.

A disagreement between sources is recorded rather than smoothed into one confident number. None of these is a Signal.
