1) Aquistion ergot alkaloids (ergotamin, ergocrystine, ergocryptine, ergoline etc.)--Can get these from either a pharmecutical manufacturer or from the natirally occuring fungus, or not cost effectively from morning glories, hawaiin baby woodrose seeds etc. You can also grow the culture and extract the m from there.
2) Make into alkaloids into lysergic acid monohydrate (ie potassium, lithium, calcium, barium, ammonium etc.) or d-iso lysergic acid hydrazide.
3) Make hydrazide into azide and then into d-lsd, or make monohydrate into d-lsd and d-iso lsd and epimerize d-iso lsd into d-lsd after seperating by chromotography.
4)Use fractional crystallization to crystallize lsd and then eat it.
This is as basic as i can make it, these are all the basic steps but the process is much more drawn out and involves the aquisition of some really pain in the ass chemicals. I personally have decided that making it is pretty much impossible with out spending a tremendous amount of effort in planning and aquiring the chemicals. But i'm just a stoner with not all that much incentive to do anything requiring lots of effort. Maybe you aren't. So make millions of doses and give them to every one for free and the world will be a better place for the duration of the trip and then it will suck again.
