What is the highest dose of mushrooms you have done?
Terence McKenna mentioned various experiences with different dosages of psilocybin mushrooms throughout his life. One notable high-dose experience he recounted involved taking nine grams of dried mushrooms, which he considered a high dose since five grams is usually regarded as a substantial amount. He warned against doses higher than ten grams, stating that "your powers of reportage will be damaged" and emphasizing that more than ten grams is "a hell of a wallop" 13.
In another account, Terence described experimenting with doses of five grams dried or fifty grams fresh approximately every two weeks, which he found to be a "prudent" high dose for him during that period of his life 11.
These examples illustrate that Terence explored a range of dosages, from moderate to quite high, always with a keen awareness of the effects and implications of such intense psychedelic experiences.
