-RE Impact of heat and time soaking: I have not yet worked with heat, only soaks at room temp. As far as soaking time is concerned, I can only say that a little less than three weeks versus two months showed no discernible difference in terms of potency.

-I indeed have not tried the lime route yet. I am a little resistant to trying it because I have no idea what I am doing, but it is on my list for possible future experiments. My next experiment will be to consume the residue of an IPA soak and note possible differences with 96% grain alcohol soaks. Depending on the results I will afterwards probably try the lime route or re-x'ing the evaporated AE residue with naphta.

-I have never heard of doing DMT sublingually. You think just putting the AE residue under your tongue would work? I expect the taste would be disgusting. Also, the residue that an IPA soak leaves weighs about as much as the residue of a grain alcohol soak, but the volume of the latter is about 4 times that of the previous, possibly making sublingual consumption relatively uncomfortable.
