10-15 mg for people sensitive to psychedelics, 25-30 mg for people who aren't. That's what I'd do anyway.
I would go as far as to say that it is one of the only synthetic psychedelics besides LSD that I have ever tried that I actually think is worth taking for any reason other than checking it off your to-do list.
To me, they are indistinguishable in every way, and worlds apart from every other psychedelic I have tried.
Can you describe the general effects to me please?
