I found an easy and good way to extract a high yield of pure white crystals, it takes some patience, but the reward is huge.
-Find a jar that fits about 3 litres.
-Hexane, or Naptha.
-Lye or something like it (granulated).
-Mimosa Hostilis (pre powdered is fine).
-3 or 4 collection jars.
-Pipette, or an improvised one.
-Now put 2.25 litres of water in the jar and ad 100 g. of granulated Lye/NaOH to it, then ad 100 g. of pre powdered Mimosa Hostilis, mix it untill everything is dissolved, close it, and put the jar away for 24 hours, less is good too, but 24 hours will give better results.
-Now, after 24 hours open the jar and ad 100 ml. Naptha/Hexane/Heptane, close the jar and roll it gently -(do not shake, you don't want emulsions)- around for 10 minutes (you can do less, but again, for better results 10 minutes is advised).
-let possible emulsions fade away, and roll the jar again for another 10 minutes.
-Repeat this one more time, so you rolled that jar for 30 minutes, let possible emulsions fade away, and open the jar to extract the top layer of Naptha, put this Naptha in one of your collection jars and put that jar in the freezer.
-Now repeat all of this again, ad 100 ml. Naptha, and roll that jar again, this time 8 minutes is fine, do this as you did before, so you have rolled the jar for 24 minutes, again extract the top layer, and put it in another collection jar in the freezer.
-Ad 100ml. of Naptha and repeat the whole process again, this time 6 minutes is fine, so after approximatly 18 minutes of jar rolling you can extract the last layer and collect it in another third jar, you can put that in the freezer aswell.
-Best is to leave the jars in the freezer for 48 hours, after 24 hours you could collect your yield, but if you wan't a higher yield be patient and wait 24 hours more, do not disturb or shake the jars when they are in the freezer!
-After 48 hours you can take them out, and take another jar, put a coffee filter in it, and empty the collection jars in that filter, put the remaining Naptha in a jar, you can re-use it for later extractions.
-Let the crystals dry out, cut possible chunks with a razorblade into small pieces, and let them dry out completely, so all Naptha is evaporized.
There will still be some residue in the collection jars, but this will get oily when you'll try to scrape it out, best is to re-crystalize the residue.
The collected crystals don't need to be re-crystalized if you have only extracted the Naptha, without any brown sludge, otherwise you can re-crystalize.
-Using this method should get you an amount of 0.6 g. white crystals of DMT.
I tried 4 different methods, and this worked out the best by far.
Also, it's best to store the collection jars in the fridge for an hour before putting them in the freezer, by doing this the jars will cool down more slowly, wich will produce more crystals aswell, also make sure your freezer is on it's maximum capacity, the colder the better.
Peace.
