NuKlear (URINE ADDITIVE) was perfected after thousands of hours of lab work. It is a great breakthrough - the smallest, most potent, undetectable urine purifier sold today. It's predecessor "Klear" was so successful that the drug testing industry devised a test specifically to test for Klear. Counter measures were called for and after a year and a half your scientists perfected NuKlear. NuKlear is EASY TO USE and CLEARS ALL POSITIVES FOR EMIT (THE BASIC URINE TEST). USED SUCCESSFULLY FOR 13 YEARS.
