Significant Libido Boost the Day after Red Bull Consumption?

I am not a regular drinker of Red Bull, maybe one or two a year. However, I notice that every time I drink a red bull… I experience a very noticeable libido increase the next day.

Any thoughts on what ingredient or combination of ingredients could be responsible for this effect? Other than glucuronolactone which I know nothing about, there is nothing that stands out to me.
