The only thing you can get from a health food store/head shop that will help is creatine to help in your dilution plans or synthetic urine if you sub. All the Qcarbo and other detox drinks in the world won't cover you if your creatinine or SG gets checked. BTW - red, white, blue cranberry won't do a thing either. If it were that easy people wouldn't stress urine tests. In other words, if you ever DO manage to pass using a detox drink, it means you would have passed anyway. If you fail, it is usually because the sample ends up being too dilute.
