I have in the past micro dosed on Iboga, Shrooms, I can tell you that they work a lot of good brain activity and even generate new brain cells. It also starts redirecting neuron to fire different pathways promotes good neuron health a kind inner brain massage which in the process brings up old forgotten memories stored ages ago and sorta reprocesses them in a new light of the present. This stuff Iboga is genuinely good but you have to treat it with respect and do you homework of finding out how to best use it.
Have a look at some of these vids perhaps briefly skim them and then picture the GB doing the stuff and what would happen. I'm sure they would make changes for the good and surprise the hell out of us.
