Not tested(yet) but quite good, I am not going to explain much since I hace just popped some 2C-B and I can't think clearly.
You can use any alcohol solvent like IPA or methanol, but the best option is food grade ethanol. I usually distill it from Vodka
Anyway first it is recommended to do a soxhlet extraction, However maceration would work just as fine(a maceration of a full 24h would do it)
I usually use 3ml of solvent per gram since I usually do a soxhlet extraction. If you feel unsure just use 6ml per Gram, same with maceration.
Se start with finely powdered stem and buds dried 15min un a oven at 250f
Anyway with this you decide how much plant material you want to work with.
When you have soxhlet extract it or macerate it and vacuum filter. Then most of the solvent is destiled off and the rest is evaporates off. An alternativa step is to put the soxhlet extraction in the sun to eliminate most of the cjlorophill.
Maybe i Will do a more detailed TEK when I al less high
