This sounds very intriguing. Was a big psychonaut in my early years. Did a lot of LSD, Mushrooms, Ketamine, various research chemicals. Have had some mind bending experiences when mixing, but after settling down and getting older I haven't been tripping much.
However, I went to Amsterdam a year back and had some of the truffles there. Had such a good time and have been looking for another trip, so this sounds like something that would be right up my ally.
Would be interested in getting these if they go on sale.
