Y'all need to back the fuck up an' learn some chemistry.
The reason the Lemon Tek works good is due to two properties of the active components in the fungus (fungus among us.. say that 3x fast).
The first is the conversion of psilocybin to psilocin.
Psilocybin is a chemical compound known as an
ester - a compound that's made of an alcohol and an acid bound together. Now, when you expose esters to
acidic or basic conditions in water, they snap open to the parent alcohol and acid. In our case, the lemon juice opens psilocybin to
psilocin and
phosphoric acid (scary sounding - but it's used in cola as an acidifier and is safe for use in food). This reaction happens in your stomach when psilocybin hits the hydrochloric acid -
it's not restricted to being done by enzymes! They just help the reaction happen under more mild conditions (like in your blood, where excess acid would be a Bad Thing).
The other "half" of the tek comes from the fact that *pure* psilocin freebase doesn't dissolve very well in water. It has to form a salt first, and it needs an acid to do that. Either the
citric acid or the generated
phosphoric acid complexes with the psilocin (and psilocybin too!) and makes it into an ionic compound which dissolve in water easily (e.g.
psilocin citrate). Having psilocin or other alkaloids already dissolved in water means
you don't have to wait for them to leach out of the mushrooms sitting in your stomach - they can diffuse right across the small intestine and get to partyin'. This means a
faster onset.
The same reaction happens with 4-AcO-DMT. It's converted to psilocin and acetic acid.
So in summary, while the Lemon Tek might not provide any serious potentiation, it does have a scientific basis for why people do it, and why it kicks in rapidly.
