Lol, buying the kratom extract isn't the only was to obtain it. If you can buy kratom, you can make your own extract. Grind up the kratom, if it isn't already, and add it to a jar filled distilled water(3-20 cups depending on amount kratom) and a half a cup of lemon juice(to acidify the brew). Let the kratom sit in the jar for 3 hours to a few days, shake well from time to time.
Then pour the mixture into a pot and set the stove at simmer. I usually leave the lid on for an hour or two, and then I strain the mixture through T-shirt material or cheesecloth, removing all the kratom waiste leaving the alkaloids in the mixture. I continue to boil this until I'm eventually left with a thicker sludge at the bottom. I pour and scrape this into a glass baking dish and continue to evaporate the rest of liquid off with a hair dryer that I put on a clamp so it blows over the mixture. Once this is all done I'm left with a thin, slightly oily tar that I scrape off with a razor blade. Wholla, there's your extract. I'm also gonna experiment with different methods with ethanol and isopryol alchohal to see if I can get a less oily, more potent extract. I'm also might see if I can clean out the extract a little more using naptha, but I have to do some more reserch before I try this.
