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

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.

Taurine

Product declaration: Taurine: 1 g
Selected studied range: 1000 to 3000 mg
Protocol and duration: per day, acutely across 6 to 15 days
Studied context: Studied for aerobic performance (VO2max, time-to-exhaustion, time-trial performance), anaerobic/strength performance, exercise-induced muscle damage, and recovery. A 2018 review ("Taurine in sports and exercise," PMC8152067) reports small-to-moderate improvements across several of these outcomes in some studies.
Limitations: The 2018 review states plainly: "limited and varied findings prohibit definitive conclusions regarding the efficacy of taurine on aerobic and anaerobic performance," and separately notes no peer-reviewed evidence exists for an independent role of taurine in skeletal-muscle hypertrophy.

Beta-alanine

Product declaration: Beta-Alanine: 800 mg
Selected studied range: 4000 to 6000 mg
Protocol and duration: per day in divided doses, for at least 2 to 4 weeks, not as a single pre-workout dose
Studied context: Studied for high-intensity exercise capacity in the 60-240 second range via elevation of muscle carnosine, which acts as an intracellular pH buffer against acidosis. ISSN 2015 position stand: greatest performance benefits in "open end-point" tasks/time trials lasting 1-4 minutes; some benefit noted in aerobic exercise up to roughly 25 minutes; attenuation of neuromuscular fatigue, particularly noted in older adults.
Limitations: Strength/resistance-training outcomes remain mixed; training volume may increase without a clear strength gain. Tasks under 60 seconds do not show benefit. Endurance benefit beyond about 25 minutes is not established. Long-term safety data beyond roughly a year, and effects in special/tactical populations, are flagged as needing more research.

L-citrulline

Product declaration: L-Citrulline: 750 mg
Selected studied range: 3000 to 9000 mg
Protocol and duration: per day, in the studies NIH ODS summarizes
Studied context: Studied as a nitric-oxide pathway precursor (converted to arginine via the urea cycle) for aerobic exercise performance measures such as oxygen-uptake (VO2) kinetics, blood lactate, and rate of perceived exertion, and for acute resistance-exercise performance and muscle oxygenation. NIH ODS describes evidence for enhancing performance as limited, with few studies and conflicting results.
Limitations: A 2022 systematic review/meta-analysis found no significant benefit for endurance-performance outcomes specifically. A single 8 g acute dose did not enhance isometric force production, muscle endurance, or muscle-oxygenation parameters in one resistance-exercise study. NIH ODS characterizes overall performance-enhancement evidence as limited.

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.

No source conflict is recorded on this Record. That is not a claim that every source agrees, only that none we read disagreed.
