"Red Bull Experiment"

A silly experiment by madHarbl.

What will happen if I consume four cans of Red Bull over a short period of time?

Four (4) cans of Red Bull to be consumed. Each can 355 mL serving. Each can served chilled.

No food or other drink consumed at least twelve (12) hours before experiment, or during.

No exercise performed during experiment.

No tobacco products consumed during experiment.

Blood pressure (BP) measured periodically (approx. 20 minutes after can consumption) during experiment.

Blood pressure measured twice each time to try to eliminate error with the machine.



12:33 BP = 128 / 87
12:35 BP = 133 / 85

12:35 *** FIRST CAN OF RED BULL CONSUMED ***

12:55 BP = 135 / 82
12:57 BP = 132 / 82

1:00 *** SECOND CAN OF RED BULL CONSUMED ***

1:20 BP = 127 / 78
1:25 BP = 128 / 77

1:30 *** THIRD CAN OF RED BULL CONSUMED ***

1:55 BP = 132 / 80
1:57 BP = 128 / 82

2:00 *** FOURTH, FINAL CAN OF RED BULL CONSUMED ***

2:20 BP = 128 / 77
2:23 BP = 111 / 86


I did measure my blood pressure once five minutes after consuming the third can, and noticed blood pressure was slightly elevated (140 / 83).

I had two bathroom (urination) breaks during the experiment, consistent with caffeine overdose.

Nothing else noticable!
