I agree that they all take several hours, personally I think at least around four or five hours to really peak, sometimes more, though I do usually feel more of them faster than I did with this. This is definitely familiar with the number of psychedelic amphetamines I've taken before now, but it does still feel relatively unique to me, though it's hard for me to define it too much at this level of activity. I think the most impressive thing I've seen so far is the hallucinogenic potential, which is really the most impressive thing I expected to see about it going in based on the reports, but there's plenty of time left to go still.
I definitely do feel like I'm hitting the point where things are maybe shifting more, but it's hard to tell first time around. It definitely feels nice so far though.

I really can't complain about much, which is already a plus when taking a novel psychedelic amphetamine for me.
