I never thought of getting an extract, that sounds like a good idea.  Is one preferred over the other hcl/freebase or harmine/harmaline?  I was checking out the caapi extraction in the FAQ and it looks like something I could pull off also letting me know where my caapi stands as far as quality.  That sounds like a valid next step.  I'll check out the suppliers forum too just incase one of them has it included on their list so I can avoid the off chance I might get something with some unwanted chemicals still in the final product.
