I have been microdosing (300mg enhanced root bark) for eight days. I find it to be quite remarkable. Clearly mood lightening, mildly stimulating, emotionally grounding. I am sure it is not placebo. I will try to remain aware as I understand that it will build up in my system due to being fat soluble. I also believe that it may potentiate other substances taken while using Iboga. Far from an expert but this has been my experience thus far.
