I wouldn't say something was true unless I could offer a sensible reason as to why it might be true. I could just as easily say "Standing on one leg while wearing your mothers pantyhose on your head makes mushrooms hit faster". Would you really feel the need to go out and do it?
Not that you implied otherwise but I am not saying anything is 'true' but rather that my personal experience tells me there is something going on here. And it's not random so you can leave the reductio ad absurdum at the door. You tell me how selective "Citrus acetyl esterase" is for example and how plausible is it that phosphorylesterases in the juice would or could play an active role in this story? The wildest result I had was with multifruit juice, I imagine if you want a really diverse population of enzymes in your formula that's the way to go.
My experience with mushroom tea is relatively limited but the experiences I have had were on average barely kept near normal result (from eating the mushrooms themselves) in its effects. I can't be positive that tea is actually weaker, and the fact that I didn't always eat the leftover mushroom pulp may have something to do with this. But as a control group for fruit juice preparations, it fails to nullify the fruit juice / lemon tek experiments.
I'm also thinking: let us take the hypothesis that the lemon tek works, are enzymes even necessary or do simple acid/base equilibrium laws dictate that the normal ester : indolol ratio is shifted towards the indolol because the acidity results in proportional protonation? This may mean that a process that is otherwise also taking place in the stomach can start already before ingestion. So instead of gradually releasing both alkaloids (I take it the zwitterion is rather soluble and absorbtion-friendly as well), it's the indolol that is ready and set in the starting blocks when it's all gulped down.
As I said before: the liquid medium would provide an important role indeed. If a lemon tek preparation would be put in a food dehydrator and the result would be eaten I wonder if this would slow it down. Also I wonder if heat-treated lemon juice that would denature the enzymes would prove an interesting control group.
Damn it, now we need a group of shroomers who are down for a long-term experiment, of course preferably they would not be aware of the whole lemon tek theory so that placebo would not logically play a role. :D
I may sound like a believer but it remains a theory and I am well aware of that. At the same time I am very much intrigued and interested in plausible explanations, though things like this are notorious for hanging around for years without anyone investing the time and energy to get to the bottom of it.
The number of people who voted they notice no difference is worrying, for example the LSA -> LAH theory seems to have a much better success ratio.
Then again, a lot of people believe vitamin C and sugar are compounds that abort a trip, still somehow this lemon tek thing evolved. I mean stranger things have evolved that are downright outrageous and silly, but it didn't seem like a particularly placebo-sensitive premise.
