Lowest tech: smell it, taste it, wait to see if it kills you lol.
It's $12.99
Its (probably) fine. I gave away a bunch of bottles as gifts though. Less willing to gamble with them lol.
Great idea!

Digital PH Meter, PH Meter 0.01 High-Precision Pocket Water Quality Tester, PH Range 0-14, Suitable for Accurate Testing of Drinking Water, Aquariums, Swimming Pools, Hydroponics (Yellow) https://www.amazon.com/dp/B091SKXTXD/ref=cm_sw_r_cp_api_glt_fabc_596B3378RZQ3KVSWP7QN
Get a pH meter ( https://www.amazon.com/dp/B091SKXTXD ) and some citric acid powder. Add just a tiny bit of the powder to water in a pot until it measures between 2.5-2.9 pH, targeting 2.9. Bring the water to a boil. Add diced fresh mushrooms and simmer at 90-100C with the pot lid on for 2.5-3 hours. Strain and toss mushrooms, let the liquid cool, and freeze whatever you can't use within a week for later. When you want to use more, let it thaw for a half hour and then break off a chunk for the fridge. This method increases potency by converting all the ibotenic acid to muscimol, also therefore eliminates the ibotenic acid which is neurotoxic, and provides consistent dosing for potentially weeks or months if you make it potent enough. Make sure to put as many mushrooms in the pot as possible, and make sure to keep the lid on the whole time!
Dried mushrooms can also be used for this exact same method but the potency will be reduced. Start by taking 1 teaspoon during the day to see if it has any effect, then the next separate day add an additional teaspoon, and keep adding 1 teaspoon each new day until you find the dosing that's right for you.
Once you find your dose, you can using for microdosing during the day, taking before bed to help with sleep, or taking larger doses for a more spiritual experience (but most prefer smaller doses as larger ones can be uncomfortable -- higher doses can include repetitive thoughts/actions and a delirium-like state).
Get a pH meter ( https://www.amazon.com/dp/B091SKXTXD/ref=cm_sw_r_cp_awdb_imm_RA4KBXGF2BTQQP5QGZH7 ) and some citric acid powder. Put water in a pot on the stove, add just a tiny bit of citric acid powder and then measure the water's pH. You want to get the pH between 2.5-2.9 (2.9 is better in case some water evaporates), then add as many mushrooms as you can, simmer at 90-100C for 3 hours with the pot lid on, then strain the mushrooms out and toss them. You'll now have a liquid where all the ibotenic acid has converted to muscimol, and you can freeze whatever you can't use within a week for later. Start with a small amount to find the dosage, then you can try increasing a little each new day you take it.
