I have quick fix plus (Canadian version) but haven't used it yet. What synthetic urine do you guys use and the success rates? Have mine for school drug tests
i have 4 randoms at Quest labs using powdered synthetic from passitkit . only pre filled Liquid urine can be detected as they use biocides to keep i t shelf stable . it all depends on who is testing no tall places are labs not all techs validate samples . many places are just collection centers that use instant cups .
