POWER YOUR PERFORMANCE WITH CAFFEINE AND KEY NUTRIENTS

Caffeine is one of the most widely used performance-enhancing aids among athletes across many sports and competitive levels.

Caffeine boosts performance through several mechanisms, including its effects on the central nervous system, optimization of muscle metabolism and energy use, and increased calcium availability in muscle fibers (1),(2),(3).

Supplementing with caffeine at 3–6 mg per kilogram (1.5–3 mg per pound) of body weight has been shown to improve performance in endurance sports (like cycling, running, and cross-country skiing), enhance sport-specific performance in football, basketball, and rugby, increase muscle endurance, strength, and power during resistance training, and support cognitive function during exercise—improving attention, reaction time, and accuracy. SiS Caffeine Shot delivers 150 mg of caffeine, enough to provide these proven benefits for both physical and mental performance during exercise.

Magnesium helps maintain normal muscle and nerve function, while vitamins B6, B9, and B12 reduce tiredness and fatigue. Citrulline malate is also included, as research suggests it can enhance exercise performance by supporting nitric oxide production, reducing lactate buildup, and improving ATP generation for energy.

KNOW YOUR CAFFEINE

Caffeine typically takes 30–60 minutes to reach peak levels in your bloodstream.

KNOW YOUR CAFFEINE

For shorter, high-intensity workouts or races lasting under 60–90 minutes, take your GO Caffeine Shot before starting. For longer endurance events—like marathons, century rides, or triathlons—use a shot in the final one to two hours when fatigue begins to set in and mental sharpness is most critical.

Timed correctly, the GO Caffeine Shot helps you stay alert, focused, and strong through every mile, lift, or lap. No jitters, no crash, just steady, sustained performance.
