I've been meaning to making some anhydrous acetone for FASA to salt out some xylene with but money is tight and so is time. I've been wondering though about the potency of jungle fumarates and how it compares to pure fumarates. I'd like to put some up my nose and see just how uncomfortable sub-breakthrough doses would be. Does anyone have experience with this? What about sublingual doses, are these active by themselves (without MAOI?) There must be a thread about this somewhere since higher potency in fumarate form would indicate that an MAOI like activity is taking place and not just oils protecting spice when vaporizing.
