GAT Sport | Jet Fuel Black | 90 Capsules

GAT Sport Jet Fuel Black is a high-stim capsule fat burner designed around three simultaneous jobs: elevate energy output, support thermogenesis, and improve the subjective feel of dieting through focus, mood, and stress-modulating ingredients. That matters because the best fat-loss formulas do more than simply spike stimulation. They help you train with intent, move more throughout the day, and stay mentally composed when calories are lower. Jet Fuel Black clearly aims at that broader experience.

The stimulant backbone is moderate-to-high by capsule-fat-burner standards, anchored by 144mg zümXR® extended-release caffeine plus 139mg guarana extract standardized to 22% caffeine, yielding about 30.6mg additional caffeine for a total of roughly 174.6mg. That is not extreme on paper, but delivery matters. zümXR® is designed to stretch caffeine release rather than dumping it all at once, which can create a steadier arc of alertness with less abrupt drop-off than fast-release caffeine alone. Guarana adds another methylxanthine source with a more gradual feel than anhydrous caffeine. Supporting that is 200mg theobromine, a methylxanthine that antagonizes adenosine receptors and inhibits phosphodiesterase activity, promoting mild stimulation, smooth muscle relaxation, vasodilation, and a more open, less edgy stimulant profile. Clinical literature often uses 250-500mg, so 200mg sits just under the more established standalone range, but it is still meaningfully contributive in a stacked formula.

L-theanine is here at 100mg, which is right at the lower end of the clinically supported 100-400mg range. This is one of the smarter inclusions in the formula. Mechanistically, theanine modulates glutamate signaling, increases alpha-wave activity, and supports GABA, dopamine, and serotonin tone. In practice, paired with caffeine, it helps shift energy toward focused alertness rather than jittery overstimulation.

The thermogenic side is led by 50mg CaloriBurn® GP grains of paradise extract standardized to 12.5% 6-paradol. Grains of paradise is one of the more interesting non-stimulant thermogenic ingredients because it is associated with activation of brown adipose tissue and increased energy expenditure. This is a specialized branded form rather than a generic spice inclusion, which raises confidence in standardization. Green tea extract at 100mg standardized to 50% EGCG adds catechins that complement thermogenic and oxidation-focused positioning, though this is a lighter dose than the higher-intake green tea protocols used in some fat-loss studies.

CitraFuze™ is a 200mg proprietary citrus blend combining synephrine-standardized citrus aurantium, hesperidin, naringin, N-ethyl-L-glutamine, and a citrus flavonoid component. The formula logic is clear: synephrine for adrenergic-style thermogenic support, citrus bioflavonoids for metabolic and vascular support, and a stimulant-enhancing or smoothing matrix effect. The limitation is transparency. Because this is a blend, you cannot verify how much synephrine or each flavonoid you are actually getting.

The nootropic-adaptogen layer is what separates Jet Fuel Black from commodity burners. Bacopa monnieri extract at 250mg standardized to 50% bacosides is a serious standardization level, but the dose sits below the more common 300-600mg research range, so expect supportive rather than full-spectrum bacopa effects. Mucuna pruriens extract at 150mg is included for dopaminergic and motivation-oriented positioning, but without standardization details it is difficult to judge potency, and this likely lands in the modest-effect range. RhodioPrime® rhodiola crenulata at 100mg standardized to minimum 6% salidrosides is a quality branded adaptogen, though again below the more robust dose ranges typically used for fatigue and stress resilience. Still, branded sourcing matters, and this trio likely contributes more to “dieting feels better” than dramatic nootropic output.

As a system, the formula is built intelligently: caffeine and guarana provide drive, theanine smooths it, theobromine broadens the stimulant feel, thermogenics support calorie-burning pathways, and the adaptogen/mood layer helps keep the user engaged and productive. The weakness is disclosure. Several ingredients are individually listed, but CitraFuze™ is proprietary, and the product’s broader tri-caffeine positioning is not fully transparent from available data. Compared with many fat burners, Jet Fuel Black is more sophisticated than average. Compared with fully transparent modern formulas, it loses points.

What to expect: day 1 should feel like clean rising energy, improved task focus, and a warmer, more activated training or cardio session rather than a hard stimulant slam. Over 2-4 weeks of consistent use, the cumulative value is more about routine adherence, better training consistency while dieting, and a steadier sense of momentum than about one dramatic acute effect.
