Can you handle the world’s strongest coffee?

A South African blend with lab reports boasting it’s got more than twice the caffeine of your average Starbucks roast just hit the U.S. this week. It’s called Black Insomnia Coffee, and the ground of Brazilian, Guatemalan, Ecuadorian and Rwandan coffee beans packs a bracing 702 milligrams of caffeine in every 12 ounces.

The FDA recommends adults stick to just 400 milligrams of caffeine a day, so sip at your own risk.

The coffeemaker squeezed out every milligram of caffeine naturally, without any added chemicals or sugar.  “It is time to offer something a little different – something stronger and darker, with an edge,” said creator Sean Kristafor in a statement.

“You get over 6% more caffeine from Black Insomnia than you do from 100% of our competition, because we believe if you’re not number 1, you might as well be drinking a steaming cup of number 2,” brags the brew’s brotastic Amazon description. It adds that the caffeine jolt you get from just a cup of Black Insomnia’s supposedly smooth, walnut-flavored roast as “getting a hug from your grandma at the same time as being suckerpunched by Mike Tyson.”

In comparison, the average grande Starbucks Pike Place roast is 330 milligrams for 16 ounces, per CaffeineInformer.com. A medium Dunkin Donuts brewed coffee carries 210 milligrams of caffeine per 14 ounces, and a 16-ounce medium McCafe coffee at McDonald’s packs a weaker 145-milligram caffeine punch.

You can bag a pound of Black Insomnia Coffee on Amazon for $19.99, or 50 espresso coffee capsules for $40.
