old 60's hippie here. ...the best LSD I did was called 4-way space station, blotter acid. There were 4 hits on one chunk of paper. You were only supposed to do 1/4. No one told me and I did the whole thing. Nothing was real..for over 14 hours.
I now prefer mushrooms (over LSD aka synthetics) and the mellower cruise it gives. And low doses of peyote on occasion.
