Individual results will vary and are dose-dependent. The outline below assumes you place one strip on an empty stomach.
Within 5 minutes – A gentle rise in alertness begins as the strip dissolves and green-tea–sourced caffeine enters the bloodstream directly through the mouth. You may feel a subtle sharpening of attention without any rush or edginess.
Within 20 minutes – Focus becomes unmistakably stronger. L-theanine, delivered at a 2 : 1 ratio to caffeine, tempers any stimulant roughness and promotes a calm, steady mindset. Distractions fade; simple tasks feel easier to organise.
At 60 minutes – Mental clarity and task-switching ability reach a peak that can last three to five hours. Vitamin B12 works in the background to convert dietary carbohydrates into cellular energy, supporting both brain and body during workouts, study sessions, or long meetings. Most users report zero jitters and a mild uplift in mood.
After 4–6 hours – Cognitive performance tapers gradually back to baseline with no noticeable crash. Because the caffeine dose is moderate and buffered by L-theanine, normal sleep patterns are unlikely to be affected when the strip is taken earlier in the day and not stacked with additional stimulants.
After 6 hours and beyond – You should be fully back to your usual state, free from rebound fatigue or appetite spikes. If desired, a second strip may be taken later in the day, keeping total caffeine intake within personal tolerance.
