i didnt want to bump this thread but now that it is, let me give a quick update
the newest method of preparation modifies the older ones
an entheogenic dose is 2 feet of achuma prepared like this...
part 1. make outter 5mm of despined, deskinned, darker green flesh into powder by slicing it off/dehydrating/powdering
part 2. make resin out of tea from the remains of the cacti that the dark green flesh powder was made from. first dice the remaining cacti then freeze it solid. make a 2 hour tea out of this with a dash of fumaric acid or a twist of lemon, strain and make another 2 hour tea. combine them and reduce. filter. reduce down to a liter than decant. then carefully reduce until its a few oz and dehydrate it into resin
part 3. mix the cacti powder and resin into a homogenous paste, roll this into 1cm diameter balls, and swallow after a day of calorie free fasting (at sunset)
part 4. for the next 30 min get ready for bed, then lay on your back for about 3 hours to reduce nausea. by this time you are entering pronounced effects and at hours 5-8 youll be in cactus visions
peace~
