I've vaped a few different Dr Peppers (if you look it up, I make a Dr Pepper thread just last week). I've tried Liberty Flights, Vapor 2 Life, and Cignots. Liberty Flights was horrible, tasted like actual pepper. Cignots is alright.. But doesn't really taste like the cola and is not very appealing. Vapor 4 Lifes though is REALLY good. I wouldn't say it tastes exactly like the real thing, but it's very smooth and all day vapable.
