I don't think the doses are as high as they first look, the goo seems to be mostly plant oil/fat.  I wouldn't be surprised to find out that at least 2/3rd the weight of the good is not dmt.  I wouldn't mind trying to get a crystallized final product but I just throw it in a capsule anyway so it doesn't matter too much.  The only real problem is I don't really know how much dmt im actually consuming.  My freezer doesn't seem to get cold enough to freeze precipitate so I just let the solvent dry out in glass pans and it seems to work.  If after this next session or two I still feel the need to keep returning to the stuff, ill probably order a pound or two of acacia and try a different extraction method.
