Yes, in my experience I could relate to Cat Again post. 20mg of miprocin is around 3-5g of decent mushrooms, I haven't tried more but some friends have gone up to 160mg (don't do this at home). There is some saturation level before or around 100mg mark and at that level it is quite "immersive" experience as is 10g+ of dry mushrooms or 500µg+ lsd. Out of all friends that have tried it only one out of over a dozen people found miprocin not suitable for psychedelic experience (nausea). Others were very pleased with effects. For most a nice experience is 10-15mg.
