"All my mushroom trips have been under an 1/8 (3.5g) and my highest dose of LSD was about 5-6 tabs so I really can't speak to "heroic" doses"
For the level I have gotten to with mushrooms that would match the deepest DMT breakthrough I have had I am talking like about 6g dry psilocybe cyanescens..I dont know what that would be in cubes...maybe 12g? It was a foolish thing to do at the time, I had no idea what I was in for and I never did that again anyway. Actually after that I dont think I ever dosed more than a gram of cyans...even 3.5g cubes is a really big dose for me but I am somewhat sensitive. For many people I think 3.5g cubes is not as powerful.
