A friend of mine who does not have the internet ask me to post this as he thinks it may help others who are just starting or even experienced folks extracting DMT. Here is what he has to say.

Our Q21Q21's DMT Extraction Tek

I am using the Q21Q21 Extraction Tek for religious ceremonies. From our experiments powdered produces a better yield than shredded bark which is next to impossible to get into a 100% powder form unless you have a mill. It has different names and different uses like in dyes, disinfectant; you can treat infections, burns and all kind of diseases with it. It is used in shampoos, soaps and skin care under the name of Tepezcohuite too.

I take 7.2 oz of the powder and put that into a 2 quart glass bowl. I then add 200 ml of white vinegar to it and stir with a wooden spoon. I then take 200 ml of warm purified water and add that and stir well. I would then let that sit for a few hours if not overnight. I then take 5.5 oz of pure powdered lime and add that to it. You can buy cheap electric hand mixers that work great to blend all together. Sometimes I will take it outside to blend it. It should look like an apple crisp or a lot of small round balls. After that you should let it sit for a few hours if not overnight.

Next I will heat up about 20 oz of water on the stove and when it starts to boil I will pour that into a 10 inch wide (4 inch high) stainless steel bowl sitting in the sink. Next I will take Naphtha VM&P and pour that in the powdered MHRB mix too where it just about covers all the powder and then sit that down into the hot water bath you have in the sink. The glass bowl sits just high enough above the stainless steel bowl where you do not get water in the mixture if you are careful. Stir that with a wooden spoon. I then take a flat round metal lid with a gasket on it and cover the glass bowl so it holds the heat in and you’re not getting that Naphtha smell in the house. I would let it sit at least 15 minutes minimum and sir it just a few times too.
Next remove the glass bowl and I use a 10 inch round hand held fine screen you can find in the kitchen supply department and put that on top of the bowl. Get yourself a square glass bowl with a lid that has a rubber gasket on it and snaps to get a tight seal, this keeps from getting that Naphtha smell in your freezer which is very hard to get the smell out if you do not seal the bowl well.

Next with the screen on the bowl with the powder I will hold the screen tight against the bowl and flip it up and pour the Naphtha in the square bowl. If you get fines in your square bowl just pour the liquid into a glass jar leaving just the fines in the corner which then you can wipe out. Pour the liquid back into glass bowl you will be putting in the freezer. Let it sit in the freezer several hours if not over night. Next remove from the freezer and pour that into a glass jar, if it still looks cloudy I will pour that back into the freezer jar after you dry it (the first pull) sometimes I can get about 20% of what I got out of the first pull without having to put that back in the powder. I will take the freezer jar and put that in front of a fan for about 10 minutes of so depending on how humid it is. You can then scrape out the crystals with a razor blade.

Again if your Naphtha was cloudy pour it back into your freezer container and put it back in the freezer overnight. I will get 3 three good pulls using the hot water bath plus a little more if that Naphtha was cloudy and I re-freezed it. You can do the hot water bath every few days if you want, we do 3 total.

I hope you will find this information helpful since it has worked out well for us with trial and error!

Thanks for sharing! Information about yield %% would be great to know as well.

i will ask him to get that yield for me
