In the ballpark (very much my own opinion, I don't know what the heck is actually happening and of course it's 100% subjective). There's the shock part for sure, and it's definitely much more gradual than the rocketship that is bufo, but the way things are released, and the struggle/tragedy of trying to hold on to those things in that state, and the blissful relief when you actually manage to let go is all spot on. Bufo/5 goes a bit further (and maybe that's only because that come-up is SO fast) and forces you to let go of life itself (pending the dose is right) and throws you into a near-death experience type of place (full on nondual territory). Coming back from it leaves you feeling squeaky clean, light and reborn. But that might just be me...I like to go hard and I know a lot of people really struggle with stuff (it takes some practice to be able to let go).
