The dillution thing does work but like you said they check the creatine levels and if I just dillute my pee by drinking ass loads of water then my creatine levels arent right and its just as bad as failing, at least with my situation cuz it's for probation. But to answer your question if its a lab test yes it is a lab test at least most of the time its random sometimes he gives me instant ones and sometimes he sends them in cuz if he sends them in he can test to see if I have drank any booze in the past 82 hours. I agree with you that most those drinks are bogus as hell but I am telling you I have done alot of research on what you can and cant do to pass ua's and I have tried pretty much every method there is and alot of the drinks. Most drinks dont work but I swear the strip does work without a doubt, I have had times were my stomach just couldnt handle drinking lots of water so I just take the strip drink a couple hours prior to the test, maybe I will drink a glass or 2 of water first or sometimes I will just drink a couple cups of coffee, then after taking the strip I drink a bottle of evian and I still pass. and I am sure you would agree that I cannot dillute my pee enough to pass if I only drank a couple cups of coffee and a bottle of evian. So that goes to show that this strip drink does in fact work to help you pass even without completly dilluting your pee. I know that there is no other way in my opinion that I am able to puff tough the night before my ua's and still pass without that strip drink it truely does wonders. I just wanted to add that I hope I didnt come off sounding like I think your wrong or sounding like a prick, I dont really know if I did or not but thought that it could possibly come off sounding like that and want you to know that was not intention
