It seems a bit expensive to me.
A few weeks ago I bought 200g of dried fly agaric (cap's, no stalks) with the intention of experimenting.
So far, I've simply boiled a mushroom cap in a surplus of water for ~20mins and then drank the water, discarding any solids.
I intent to use DMSO to fully convert ibotenic acid to muscimol (DMSO acts as a decarboxylation catalyst) - I found this tek on an erowid report and the results seemed very positive.
The potency of fly agaric mushrooms can vary wildly so I will likely blend & combine, say 100g and thus create a homogenised mixture. This should reduce dosage unpredictability! I can then try different teks...
Muscarine can be present in small amounts which is a general muscarinic agonist, this causes some unpleasant effects such as sweating etc. A simple remedy for this is to chew on 1 or 2 Datura Stramonium seeds as they contain a general muscarinic antagonist.
