I see you have got a lot of answers in assuming they're great who wrote them I didn't read, you can extract the psilocybin by grinding them down and I believe a 1:1 by weight of ethanol extraction in assuming with some water that's later distilled off would be my best guess at a simple way of making an extract from your mushys, I have shoeboxs of pan subtrops right now and some envy monotubs, it's been a mycology hot streak for me, contam free for so long I have burned through all the agar plates and transfers as well as most grain to grains from those first transfers, I have some purple mystic lc that colonizes so fast and makes a great product, if you're trying to extract them into liquid ethanol and or ethanol and dh20 is gonna be a route I bet you can find the process very easily they're legal a lot of places now, what I do is great and up all my aborts or side or is that don't look like something id ever give someone in a sack period and when they build up to a quart jar I put them in a magic bullet for a short burst cycle and then get this very pure lemon juice from whole foods that tastes so good and I mix the two, you can filter after a few hours but I usually let it do it's thang at Room temp for 12 hours freeze chil and filter off then drink the lemon juice in shots it's better then any chocolate bars or anything I've made, you could obviously distribute it that way and the citric acid makes a huge difference have fun out there and watch your ego lol
