I know (Burnt Toast) a lot of people say that the detox drinks dont work, but they do have vitamin b and creatine in them which is what you're supposed to drink anyway when diluting, and I just couldn't help myself from buying something that might be of help in some way...
What needs to be understood is that the creatine in the drink will do you no good when the drink is consumed on the day of the U/A (in which is required by the product directions) because it takes 2-3 days for creatine to metabolize into creatinine. Creatinine is the waste product found in urine and is tested for to determine an overdiluted sample. Any creatine-loading must be done at least 3 days before the U/A.
