The Burzynski Clinic is a controversial clinic offering an unproven cancer treatment. It was founded in 1976 and is located in Texas, United States. It is best known for the controversial 'antineoplaston therapy' devised by the clinic's founder Stanislaw Burzynski in the 1970s. Antineoplaston is Burzynski's term for a group of urine-derived peptides, peptide derivatives, and mixtures that Burzynski named to use in his 'cancer treatment'. There is no accepted scientific evidence of benefit from antineoplaston combinations for various diseases.
