Psychdelics are only intense and borderline overwhelming with a high dose, at low/micro doses they have a very different effect/expression. That's why microdosing is a thing, and why the term "museum dose" exists.
There's some research that shows that microdosing psilocybin isn't nearly (or at all) as effective as taking a regular dose. "Heroic" doses seem most promising from the neurological/neuroplasticity aspect, but yeah they can be... Quite something (even when you take care of S&S).
Never heard of the museum dose term. Can you share your experience?
Museum dose is somewhere between art gallery dose and planetarium dose. Under forest explorer dose and way under isolated beach dose.
At least in the LSD world it is said that 10mcg is a microdose, 20-50mcg is a museum dose (meaning, you can appreciate and navigate a museum while being acutely affected by the effects of the psychedelic, but not to a degree that it's overwhelming/debilitating. Anything north of 100mcg is a "proper" recreational dose, and a heroic dose I believe is anything from 300mcg upwards (very dependant on person, experience, tolerance).
