You should check out marsofold's tek it is easier and doesn't take near as long as QT's tek.Swims last extraction took a day and he had nice white crystals sitting in the freezer when he woke up the next morning.So my opinion is QT's tek is out of date and Erowid should take it down.People are going through long drawn out processes that are not necessary.Well good luck in your adventures.Peace.  8)
