If Vale is used correctly and plenty of water is drank you should be okay. Vale sells Pre-Vale, which is four capsules you take the night before you drink the vale. Basically those are just in case you havent been clean for 24-48 hours. I would have to say that the vale must have been on his side, I highly doubt it as anything to do with Target. Most employers send you to a hospital or collection site and the samples are sent to another location for testing. For instance I took a test in WI and samples were sent to ND. Hope this helps.:rasta:
