I am enthusiastic about psilocybin, it can be therapeutic for the right person. I've a history of both stuttering and using psilocybin, and while I am much much more fluent now at 40, I can't confidently correlate the two. I've also used speech therapy and other tools like reading out loud. If you do decide to trip, do your research first. There's a lot to know in order to trip properly. People with serious mental disorders should not take psilocybin, set and setting, having a trip sitter etc etc. I'd recommend starting small (one gram) to get a feel and see how you react. Lmk if you have any questions
