Tests of antineoplastons at the National Cancer Institute have never been positive. The drug company Sigma-Tau Pharmaceuticals could not duplicate Burzynski's claims for AS-2.1 and A-10. The Japanese National Cancer Institute has reported that antineoplastons did not work in their studies. No Burzynski coauthors have endorsed his use of antineoplastons in cancer patients.
Watch the film and you will find out why. They all lied about what they did. It is documented in their own reports, in court documents and in FDA documents. In one FDA report they categorically say that "antineoplastons are not toxic and highly effective."
