[FONT=Tahoma, Calibri, Verdana, Geneva, sans-serif]A step by step procedure
1. Ensure you have proper safety equipment, including safety glasses, long cuff nitrile gloves at least 8 mils thick, or nitrile or latex dish washing gloves, and a ventilated space. Keep some vinegar on hand to clean up any base spills.
2. Cover your MHRB with enough vinegar to cover it and have about a half inch of liquid over it.
3. Extract with one quarter of the volume of vinegar of nonpolar solvent (heptane is preferred, naphtha works as well, for the love of god don't use dichloromethane, chloroform or any other halogenated solvent).
4. Separate and discard the nonpolar layer. You can distill the solvent if you have a still and want to recycle solvents.
5. Raise the pH of the MHRB/vinegar suspension to 10.5-11, this will make 98% or so of the DMT into the freebase. Mix this for about an hour for te first pull or 12-24 hours for the second and subsequent pulls. Mix in about a quarter of the solution's volume of NP solvent, stir vigorously for 30 mins or shake vigorously for a few minutes.
6. Separate, save the nonpolar layer. For the first pull you can freeze the nonpolar layer immediately, for subsequent pulls pool the nonpolar layer and evaporate 80-90% of the solvent before freezing.
7. After the solvent has been in the freezer for 12-24 hours you should see a nice crop of white or yellow crystals, collect them by filtration and let them dry in a desicator (a sealed environment with a drying agent such as baked Epsom salts) for a day. You should now have some nice DMT that you can smoke, make into pharmahuasca, or convert to a salt for injection if you are really fucking brave. Have fun in other dimensions!![/FONT]
