Until someone runs some serious analysis on the material from the technique it is unknown exactly what is in there.
There is a plant analysis thread somewhere in the forum, as far as I recall, Anadenanthera's major alkaloid is bufotenine and others are mainly residuals... From that info, and if the extraction tek is as efficient as it seems yielding >1%, it is most likely that bufotenine will be the most abundant alkaloid, like way above 90%. There may be issues with 5meo not dropping out of solution when FASA is done (other chem experts may comment on this).
Can you describe your material, how much you take and what you mean by the good vibes it produces?
