I'm still wondering what the main starting compound is that magic mushrooms

biosynthesize Psilocin & Psilocybin from.

In nature they grow on Cow/Horse manure. Does this contain tryptamines?

Magic Mushrooms are known to grow very well & potent on substrates of

brown Rice flower & Straw(+Vermiculite or Perlite).

TIHKAL mentions Melatonin, a Tryptamine, to be present in both

common Rice(Oryza Sativa) & Barley(Hordeum vulgare) which' dried

stems & leaves are known & sold as "Straw".

Could Melatonin be the starting point for Psilocybin Mushrooms?

How stable is Melatonin as a molecule?

Whatever tryptamine-compounds in Rice flower & Straw

Mushrooms use to make Psilocin, it should be a stable

compound that cannot be degraded further by heat, light &

exposure to the elements.

Is Tryptophan stable? Does anyone know what's the most stable

molecule of all the natural, abundantly occuring Tryptamines?

After exposure to sunlight, air & prolonged heat during the

sterilisation of the substrate in the oven or pressure cooker,

what Tryptamine compound would be stable enough to remain in

that substrate?

Similairly I've been wondering what Phenethylamine precursor

are present in regulair cactus soil. What would the starting

material be for Peyote & San Pedro cacti to synth Mescaline

from? I've read San Pedros can even root and grow well in

100% sand or 100% perlite soil, but I wonder if they'll

contain any Mescaline.

I wonder if Cacti can be fed any unnatural starting-material

to create an unnatural endproduct.

If a san pedro, potted in a 100% sand-soil was given water

with 2C-B or 2C-C dissolved into it, would the San Pedro

be able to synthesize unnatural analogues of Mescaline?

Please share any information on Mescaline Biosynthesis in

Cacti that you know of.
