For the ones where no amount of coffee is ever enough.

The under-rested. The over-caffeinated. The painfully awesome.

This tee captures the spirit of the sinners who raw-dog life at full speed and take no prisoners. Horny, grinning, and halfway to hell — just like you.

The words “Running on Caffeine” aren’t just a statement; they’re a warning to anyone foolish enough to slow you down.

Printed on black Gildan Heavy Cotton, it’s as tough as your nervous system — pulsing with all that dark-roasted rage tearing through it.

Perfect for baristas, babysitters, and strippers — anyone who grabs the day by the balls and screams in its face.

Run wild. Stay wired. Never apologise.
