Well just an update. I passed the test and got the job. Now this was a Non-Federal, Non-DOT, 7 panel test unsupervised. I tried to hydrate alot prior to it and went into the test 5 days clean. I was a long time smoker. Day of test I drank a 24oz Gatoraid (the one with the electrolites) and took 4 asprin. About two hours before test I drank the XXtra Clear. Waited 15 minutes, refilled bottle with water and drank. Waited another 15 minutes and refilled bottle and drank. Ate two rolaids. Voided about 3 or 4 times. On way to test had to piss like a race horse so had to stop by a store to relieve myself (wasn't going to make it to the test center). Got some coffee to try to "add some color" to urine (was pretty clear in previous voids). Went to test had to do physical first which included the old drop trowl and cough hernia check (so guess good thing didnt try subbing and stashing under sack). Wasn't able to pee right off so drank about a liter more of water. Finally gave sample. Was kind of faint color wise so was a bit worried.

Sample was sent to CRL labs in Kansas and the UA guy didnt spot check it other than for temp. Anyway got job, they just told me I passed the physical and drug test so don't know results but I assume was a neg dilute but apparently since it was not Federal or DOT didn't matter to employer.

So for me XXtra Clean worked your results may very depending on how strick the test you have to take is. Mine did not seem that strick. Not saying this is a sure fire way to pass. Again was most likely a neg dilute test (or THC wasn't much of a concern for them). I dropped my sample about 2 hours after drinking XXtra Clean. XXtra Clean claims 45min effectiveness with max effectiveness at 2 hours and dimishing effects after 5 hours.

Good luck and thanks for the advice. Great site for info.
