Was this supposed to be a question ?
By the way, think about how your post may seem from the perspective of some of the older members here: A lot of people have known and been using DMT for many years, and one of the common characteristics is that the users are humbled by the effects and feel that DMT is very hard to pinpoint or understand, it puts everything one knows in question. Also extraction techniques are being constantly developed and perfected, plus there is a lot more scientific knowledge to come. So you will see that nobody, even of the senior members, will say 'they know everything about dmt'.
Maybe it was just an unfortunate choice of words and you didnt mean to sound like you think you 'know it all' but rather that you've done plenty of research, but im just giving you some constructive criticism to be careful with the words you use and to try to express humbleness, also specially because not even all the reading in the world will make you prepared for the experience.
Also why dont you just order a DMT (and a MAOI, if its for oral use) containing plant ?
