Thus far SWIM has made dmt tartrate with a roughly equimolar ratio, but due to its acidity, he suspects that it might require half as much, ie with a 2:1 ratio in favour of dmt.
IM administration as well as insufflation demonstrated no activity, and SWIM knows that both methods of administration are often dependent on the pH of the material - that is to say, it needs to be neutral. Both doses were of 75mg of dry crystalline dmt tartrate. a slightly successful IM dose using dmt ascorbate suggests that possibly if the salt could be made more neutral that it would be more effective, and may prove to work intranasally.
