if you want to screw around, i had success with isopropyl alcohol. its like crystalization in reverse, cold (like 15-20C, non condensing, not ice cold) will selectively dissolve DMT, oils, fats, gums, etc at different rates. what i did was i had a petri dish with the dmt spread out (not on purpose i just tried using the dish for crystalization yielding goo), and so i applied 6-8ml of isopropyl, swirled around, then sucked up and transfered to a test tube for storage. then i added fresh iso, and repeated this several times. the first portion that dissolved had some foul taste but, nothing compared to trying to smoke the raw goo, this could be powered through unlike the raw stuff. Next i got progressively cleaner cuts, but not only that, the effects were distinctly different. One for instance produced intense geometry and a feeling in my jaw like i could feel my teeth individually and all my organs on the come-up. another just felt like brain damage and i was living in a time loop, i got up and walked into another room and wasnt sure if i was still sitting down in the first room, or in the 2nd room and just vividly imagining it, because my reality was both, superimposed on each other.
Later fractions just became increasingly unpleasant but that didnt begin until cut 3, and all but cut 7 were actually palatable.
its not precise, but, one cut specifically was probably 100% active alkaloid, maybe not all DMT, but, i was able to smoke it by heating with a hot air gun and unlike the others it left no residue, no real taste, it was just clean as a bean. always produced some sort of effect.
theres also something you can do with naptha
naptha will have a similar effect, but with some difference. first, rinse for oils with chilled naptha. dont use much, and also youll want to save the liquid. make a slurry then use a pipette or syringe to suck that dry.
Next add hot naptha, or just, warm it with some naptha in it, and do a reX after having done the cold rinse. while at it, try to crystalize the original rinse to see the quality change, as well as see how much yield transfered over as loss. i would expect to see the crystals after this be much nicer.
if its sticky though its not neccesarily anything bad, try smoking some, if its foul, then by all means, clean, but if its clean and pleasant, it could just be oils and polymers, which are literally still DMT
