Developed by 'Geneering Products, OV600 was a powerful truth serum often used by the Galactic Empire. Unlike other serums such as Bavo Six, OV600 acted physically upon the victim, rather than mentally. When the serum detected the symptoms of lie-telling, it caused the victim's flesh to break out in a painful rash. The serum was powerful enough to cause death in severe cases.
