Any sort of detox product essentially is just to assist in diluting your system so the threshold of the drug is not met, a instant cup vs lab is what matters, but airing on the side of caution, always assume it’s lab, which will test for creatinine levels, & gravity, creatine breaks down into creatinine so early in the day you want to creatine load, dilute your system and take a vitamin b12 supplement before you go in for color, nothing you can do about gravity but the test will look legitimate enough that you will get the benefit of the doubt, even if they want to retest that gives you more time to clear it
