...I appreciate the OP is almost exactly a year old to the day, but just thought I'd chime in to echo the sentiments being expressed here. Having experience with iboga root bark, TA (Total Alkaloid) extract and pure ibogaine plus TPA, I found the ibogaine to be a short lasting experience, shallower than the experience yielded by the others, and it seemed to wash through my system a lot quicker, without any trace of the afterglow that was such a notable part of the experience with the others. In my experience, the 12 or so other alkaloids found in iboga really augment and deepen the experience, and seem to play a really important role in the afterglow. TA in particular I found much smoother on the body than the root bark, while providing the essence of the whole plant and allowing one to go deeper dosage wise than root bark alone (due to purging sooner on less material). Some practitioners maintain that pure ibogaine is useful in targeting specific things...if someone prefers the idea of using a measured dosage, I would like to echo the sentiments expressed here once again and state that one would be much better of extracting ibogaine from the much more common and easier to grow plant, Voacanga africana, and selective use of solvents when extracting may yield a cleaner profile alkaloid extract resulting in a smoother journey if one wishes to go down the TA route. Otherwise, if possible, if one is sourcing iboga, it would be best to try and seek out sustainably or ethically sourced root bark, bearing in mind it has been classified as endangered in Gabon due to overharvesting, largely to supply Western demands.
A link here put together by ibogaine expert Dr Chris Jenks on ibogaine production from Voacanga africana...the link needs updating (Chris should be contactable) but good to see such work in motion.
https://www.ibogainealli...ogaine-production-guide/The prolonged afterglow yielded by the full alkaloid extract motivated me to contact a few ibogaine practitioners...while I do see the importance of being able to use a set and known dosage of a single isolated substance, it seems to me that recovering addicts and others that could really benefit from the prolonged afterglow period in which to enact life changes could be missing out on this important part of the experience to a large degree.
