Though great whites get the bad rap, bull sharks are responsible for more (non-fatal) attacks on people.
This is commonly assumed to be a consequence of a ridiculously high amount of testosterone in bull shark blood. Indeed, bull shark testosterone has become something of a steroid craze among adventurous weight lifters.

Not only that, but even if you still decided to get your roid fix from these dangerous fish, you would need to be drinking bull shark blood by the liter to see any effects, as your body would convert 5/6ths of the stuff to inactive substances.
