Anyway my guess is the Letter represent the Three different compounds tested.
I sent what I thought one might be and I think I found the others but I am not posting them because they had a reason for not revealing them.
PS I also say research that indicates that the Cancer could also possibly be resolved using the same natural type of compound but the research was limited.
Perhaps $SBFM solved that puzzle.
Currently there are not FDA or European approved natural drugs, SBFM would be the First to have a Natural Drug Approved in either of these places.
