I have not tried fumarates. I weigh out 500mg of dmt freebase and add it to 50ml of water. Then I add the needed amount of vinegar. Be careful to not add too much, as that will burn a bit...I put it in the oven to speed up the dissolving process. When it has dissolved completely, I split the dose into 5ml vials and put in the freezer. Whenever I want a journey, I just unfreeze a vial.fractal enchantment said:^ that is something I have been wanting to try. Have you used fumerates in place of acetates? My acetate is always gooey and hard to weigh out, fumerates I can judge better since they are easier to weight..I guess since Nick Sand was injecting fumerates they should be okay for enemas..
