There are numerous teks here just for that!
Would you mind referencing a couple of the better ones? Being new to this forum, I have been searching for a TEK for a good tincture, and am confused as to the best route - with many claiming that water is fine to use, as the "magic" is H2O-soluble, and others claiming ETOH to be the better solvent, as this gets rid of the "bad" components of the journey. Therefore, would really appreciate you steering me towards 1 or 2 of your favorite protocols.
You can go crazy trying to get confirmation that x, y or z tek is the best. In order to find what's right for you, you will have to risk doing it wrong, and any extraction is going to incur some degree of wastage/inefficiency.
Personally I used 95% potable ethanol (in my case "Spirytus", which is Polish made alcohol), gave the mushrooms a long steep, 2-3 months, and keep the results in the freezer. The result is whisky coloured, has some weird spermy shit floating about in it that is unattractive but that I haven't been super bothered in trying to eradicate, and works good.
Seems the consensus is that water = oxidation. Thus 40% vodka is less good than 75%, which is less good than 95%. Personally I won't be playing with anhydrous methanol anytime soon, or any other nasty chemicals. It is not worth the few extra % of efficiency to me.
