What is the highest water temperature that a hot tub can safely be set to?

Question

I've been hearing that hot tubs should not exceed 99 degrees Fahrenheit for the users' health, however i'm sure that the max. temp has got to be higher than that.

What is the highest temp i can have the tub set to and still use it safely?
