OK, one more report directly from my experimentalist friend:
9 mg freebase 5-MeO-DMT sublingually
Stronger than the previous 4 mg, but perhaps expecting more. Until T+0:06 nasty bite, however manageable It starts slowly but becomes a bit painful. After 6-7 minutes the under-tongue becomes numbed and it is easy to handle from then on. Swallowed the saliva with the possible remains at t+0:12. Onset at T+0:15, climbing fast until a clear (++) at T+0:25. Some light CEVs and a bit body load. Mind state similar to light Ayahuasca. Not unpleasant. At T+0:50, coming down. At this period in a (+). At T+1:15 pretty much baseline
My friend further told me that he is going for one more trial with 15-20 mg freebase in a couple of days. If the experience is not completely different, he will abandon this route of administration
EDIT: My friend notified me that on the day after the experience his under-tongue feels like burned. It's not painful but a bit sore. It even makes some tongue movements difficult when speaking. Thus this was the last test of pure freebase 5-MeO-DMT sublinguallly. If this research is resumed the acetate will be tried with a MAOI
