I just watched a Netflix documentary on Dr. Butzynski. That he has cured extremely aggressive & "uncurable" cancer cases is not disputed even by the FDA (though they have tried to "get him" in various other ways). Interestingly, for those of you who believe in urine therapy, his cure involved peptides found in blood and urine. Eventually he found urine to be the cheapest source for the peptides, though no details are given on that or how he used it in his treatment.
