What we found
The panel the brand published on Oct 30, 2026 was read twice, independently, and every compared field agreed. It declares 20 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: 5000 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.

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."

Beta-alanine
A2- This label
- Beta-Alanine: 1600 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.

Choline bitartrate
A1- This label
- Choline Bitartrate: 300 mg
- Studied range
- 425 to 550 mg
Study details and limits
- Protocol and duration
- Adequate Intake for adults, a nutrient reference and not an ergogenic dose
- Studied context
- NIH ODS's Choline Health Professional fact sheet establishes choline's core physiological roles: synthesis of phosphatidylcholine and sphingomyelin for cell-membrane structure, acetylcholine (a neurotransmitter for memory, mood, and muscle control) production, methyl-group donation, gene-expression modulation, and brain development. Choline bitartrate is named as one of three supplement forms (with phosphatidylcholine and lecithin).
- Limitations
- NIH ODS states explicitly: "No studies have compared the relative bioavailability of choline from these different forms". Meaning choline bitartrate's absorption/efficacy relative to phosphatidylcholine, lecithin, or non-bitartrate forms (like alpha-GPC) is not established by NIH's own review.

L-tyrosine
A2- This label
- L-Tyrosine: 500 mg
- Studied range
- 2,000 to 2,000 mg
Study details and limits
- Protocol and duration
- per day for five days, in the cadet study
- Studied context
- Studied as the dietary precursor to norepinephrine for mitigating cognitive performance decrements under acute stress. A 2015 Military Medicine evidence review (rapid evidence assessment, 14 trials: 10 RCTs + 4 controlled clinical trials) issued a "weak recommendation" in favor of tyrosine for cognitive stress specifically, stating "all studies showed a positive effect" on that outcome. A widely cited primary study (Deijen et al. 1999, Brain Research Bulletin) gave cadets 2 g tyrosine daily for five days during a combat training course and found better memory and tracking-task performance, plus lower systolic blood pressure, versus a carbohydrate control.
- Limitations
- The 2015 Military Medicine review states explicitly that "no recommendation could be made" for tyrosine's effect on physical performance under stressful physical conditions, and concludes "available evidence is insufficient to make confident recommendations on the effectiveness of tyrosine for mitigating stress effects on physical/cognitive performance" overall, despite the positive signal on cognition. A separate heat-stress study found tyrosine ingestion did not influence cognitive function or physical performance during exercise heat stress despite raised serum tyrosine. NIH ODS's exercise/athletic-performance fact sheet does not cover tyrosine at all.
Selected evidence: Deijen et al., Brain Research Bulletin, 1999
L-theanine
A2- This label
- L-Theanine: 50 mg
- Studied range
- 12 to 400 mg
Study details and limits
- Protocol and duration
- per day across trials, with most using 200 mg
- Studied context
- Studied for attention/reaction-time measures and for stress-related relaxation without sedation. A meta-analysis/systematic review of 31 randomized controlled trials (n=1,168) found a single 200 mg dose taken 30-60 minutes before testing significantly improved choice reaction time (SMD = 0.51, 95% CI 0.25-0.77); a subset of 5 RCTs in 148 healthy adults found a dose-dependent effect on rapid visual information processing and recognition visual reaction time.
- Limitations
- The review describing itself as "promising, but not completely conclusive" signals the overall evidence base has not reached firm consensus strength despite the positive reaction-time finding.

SAFETY ADVISORY · A2
Alpha-GPC 50% material. This material is standardized to Alpha-GPC. A 2021 JAMA Network Open study of about 12 million adults reported an association between alpha-GPC use and 10-year stroke risk, in a dose and duration response pattern. The authors flag confounding, and association is not causation.
