try finding ethanol, i belive HEAT fuel line antifreeze is pure ethanol (might be methanol !!DEADLY DONT USE IF IT IS!!). you could allways set up a pot still with a pressure cooker and some 1/4" copper tubing and distill scope or lysterine (or cheap vodka for that matter) to get nearly 200 proof grain alcohol. heres a link to a good process that shulgin himself preformed and verified that it works.
http://deoxy.org/wiki/Mushrooms/Alkaloid_Extraction good luck man just keep any crystals that form under alcohol or they'll oxidize and loose potency. i hear that roughly 3ml is a A+++ if you use 1oz of mush in your extraction and bring it down to 50ml or so.
