This is a cup of coffee to die for.

Death Wish Coffee bills itself as “the world’s strongest coffee,” offering more than double the caffeine found in a regular cup, the Los Angeles Times reported.

A cup of coffee contains about 320 milligrams of caffeine, says the American Beverage Association, according to the L.A. Times. By contrast, 16 ounces of Death Wish rings in with about 660 milligrams.

The company, which refers to “sissy Starbucks” on its website, is so proud of its potent brew that it offers to buy back your Death Wish if you can find a stronger blend. The coffee costs about $20 a pound.
