Additives work in two different ways.
Some act chemically to destroy toxins in the urine and some block the capability of the test to detect toxins in the urine. We have tested several additives currently on the market and believe that Clear Choice and Urine Luck are the finest products being sold today. The products come in a 6 mL micro-vial about the size of a pinky finger, that is easily concealed. It will destroy all toxins in a urine sample. It will even destroy prescription medications, so you don't need to list prescription drugs you are taking.
