... nnnoooo, not at all.
We'll have to disagree on that sekio - do a search for "psilocybin metabolized by the liver" and there's a few hundred pages on it. I believe it was established in scientific studies as far back as 1962.
Which brings up the interesting point that psilocybin, if it's being metabolized by the liver, is passing through the powerful hydrochloric acid in your stomach unchanged. So if stomach acid has no effect on it, what effect does soaking it in lemon juice have?
the facts are right in front of you
Hold on cryptix, the facts are right in front of me and they're saying quite clearly that lemon juice has no effect whatsoever, psilocybin is metabolized in the liver - if stomach hydrochloric acid has no effect on it, what does lemon juice? What say you?
you've never even tried it.
It's not about "trying it" - that's the whole power of placebo. Psilocybin puts you in a highly suggestible state of mind. If someone gave me a capsuled mushroom and said "This is the most powerful, visual mushroom strain that has ever been grown" I'd probably have a powerful trip even if it was cubensis. You have to take the placebo effect out of this.
I've been hearing stories about "orange juice makes you trip harder, no, orange juice kills the trip, no blackcurrant juice is the one that makes you trip harder" for years. Eventually you realise that whatever someone beleives will make them trip harder will work purely by placebo.
