What it means
The label you can check against.
What we found
The panel the brand published on Oct 30, 2026 was read twice, independently, and every compared field agreed. It declares 10 dosed lines. No confirmed formula change is on file for this product.
What we can’t tell you yet
A missing earlier label is not proof nothing changed, and a product record never establishes what is inside a particular tub. Dates are observation dates, not manufacture dates.

Research context
Research-dose context
This label beside selected research
Selected evidence, not a universal effective dose. It does not establish safety, effectiveness, or a dose recommendation for this product.
L-citrulline
A1- This label
- L-Citrulline: 8000 mg
- Studied range
- 3,000 to 9,000 mg
Study details and limits
- 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.

Beta-alanine
A2- This label
- Beta-Alanine: 3200 mg
- Studied range
- 4,000 to 6,000 mg
Study details and limits
- 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.

Betaine anhydrous
A1- This label
- Betaine Anhydrous: 2500 mg
- Studied range
- 2,000 to 5,000 mg
Study details and limits
- Protocol and duration
- per day, studied for up to 15 days
- Studied context
- NIH ODS describes betaine as studied for strength- and power-based performance in bodybuilders and cyclists, with "potential but modest" improvements from a limited set of small, sometimes conflicting studies. A 2024/2025 systematic review focused specifically on endurance performance (VO2max, time-to-exhaustion, time-to-completion, power output).
- Limitations
- The endurance systematic review explicitly states "limited and inconclusive evidence regarding the definitive ergogenic effect of betaine supplementation on endurance exercise performance". Only 2 of 5 reviewed studies showed a significant improvement, and the authors call for "additional, more rigorous research."
