What is it?

There is a lack of evidence to support any anticancer effects of antineoplastons in humans.

Antineoplastons are compounds that were first isolated from human urine and blood by Stanislaw Burzynski. He claims that they promote the body’s natural defenses against cancer. However, there is insufficient evidence to support this theory. Adverse reactions from antineoplaston treatment include confusion, sleepiness, worsening of seizures, headache, vomiting, and fatigue.
