Using soda syrup in brewing?

I just bought 3 Coca Cola cory kegs that are still full of syrup. Is there any way to use it in brewing, or should I just dump it out?

I’d dump it, probably loaded with preservatives.

Carb up some water for a seltzer tap, and use the syrup as it was intended… assuming it isn’t expired.

Yuck! :?

Once, on a whim, I decided to ferment some root beer extract. It was about the worst thing ever. I kind of expected it would be terrible, and was not surprised. Sick!
