How long does Bang Energy Black Cherry Vanilla stay in your system?
Our model halves caffeine every 5 hours for average metabolism, and every 3 or 8 hours for fast or slow metabolism. From one 16 oz can of Bang Energy Black Cherry Vanilla (300 mg), about 150 mg is still in your body 5 hours later and about 75 mg after 10 hours. If you clear caffeine slowly (an 8-hour half-life), about 126 mg is left after 10 hours.
