SWIM once took about 25 grams of home grown Psilocybe cubensis thinking they were inactive (they were boiled for a while).
Folks, boiling does NOT inactivate them. Maybe boiling for many hours might, but they were as strong as non-boiled mushrooms. SWIM ate them all and tripped harder than he ever tripped on anything in his life within 5 minutes, and that was just the beginning of the trip. It was a life shaking experience, and it caused minor internal bleeding. Psilocybin is an anti-coagulant at high doses.
I don't recommend taking super large doses of any psilocybin containing mushrooms. Waking up the next morning with bruise spots all over from broken blood vessels is not at all healthy.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
