Maybe if someone mixed 1/4 DMT fumarate 1/2 DMSO and 1/4 of some kind of binder or filler into a paste and tried that they might have good results. SWIM thinks that the DMSO would greatly increase the absorption.

Salts probably won't burn too much because they aren't freebase (and SWIM assumes that whatever is in virola resin is a salt), this might also explain the reason that virola absorbs better (something about blood pH and blood buffers, SWIM doesn't remember exactly).
