McDonald's is adding new breakfast sandwiches with 3 times as much meat to its menu. Here's how they actually taste. (MCD)

The meatiest McDonald's breakfast sandwiches ever have arrived.

On Thursday, the fast-food giant debuted Triple Breakfast Stacks — essentially revamped versions of the biscuit, the McMuffin, and the McGriddle, with three times as much meat as the typical breakfast sandwich. Each contains eggs, two sausage patties, and bacon slices.

Business Insider first reported on the company's plans to introduce the sandwiches after viewing internal documents from McDonald's. So, we knew how to create these meat-filled masterpieces.

With this knowledge, we crafted our own Triple Breakfast Stacks for a taste test ahead of Thursday's launch.

Here's what the super-meaty breakfast sandwiches are actually like:

The interplay of sausage and bacon — previously unheard of on a McDonald's breakfast sandwich — works disturbingly well, with the salty, savory flavors complementing one another nicely.

The second sausage, however, is a bit much. The syrupy McGriddle Stack, especially, packs in enough grease to immobilize the eater for the rest of the day.

McDonald's understands what makes a breakfast sandwich work. The Breakfast Triple Stacks are greasier than the average breakfast sandwich and won't replace the classics in our day-to-day diet. But, they're a disgustingly delectable addition.
