Well prepared, but still have questions

Hi guys I just joined today after weeks of reading the boards and researching. I have a drug test in 2 days for pre employment which I cannot screw up since I have put in my 2 weeks notice. To start off I have not had a smoke in almost a month 27 days or so Friday will be a month before that 2 weeks before that everyday. I am roughly 6 foot 250 pounds large frame and do not excercise so I am assuming I have a slow metabolism. Two weeks ago I went and took the instant test at the local drug testing facility. Showed up negative for THC faint line, but was visible. I decided 4 days later to take the lab test to be on the safe side little more expensive, but wanted piece of mind. It came back positive for THC. I ordered the clean urine from Ureasample and the mini transporter kit. I am still cautious about the temp being at right temp. Even purchased digital therm to verify the day of. Anybody have luck with these? I bought the at home test kit today from local CVS First check I think. It showed up negative, but with line not being as dark as control line, but was visible. Had friend of mine take same test who has never smoked and it was as dark as the control line itself. I also was given a free bottle of Strip from GNC by a friend who did not need it. What would be the safe bet to go on here since I cannot fail this test? By the way I stay on the low carb high protein diet like a 1.0 lb of meat a day so diluting might not be bad when checking creatine levels.Does the strip drink work? should I dilute and use the drink. Or use the clean urine? Without being a hundred percent positive of everything I want to make sure.. Obviously I have prepared and have secondary backup plans, but want to get it right the first time I only have one chance. I want to say thanks to everybody that has posted on here I have learned alot from your posts...

A month is a good time to get your tolerance down - just drink plenty of water everyday from now on and you'll ace your test. Try taking a multivitamin everyday as well, as it helps your body flush toxins easier when all the right vitamins are present.

Well I have decided to not use the strip since I have read people failing the test while using it. I guess I will be using the clean ureasample with my own urine diluted for a backup. Since the at home test came back negative yesterday dilution would probably be a good backup. My only question is on the at home test if the line is visible, but not as dark as the control does this mean that you are close to the cutoff? The only error in these test is when you are close to the cutoff. Answers, recommendations or suggestions would be greatly appreciated. Thanks.....

you boutght all that stuff, shoulda just bought detox pills to clean wipe you whole system clean in a day... you coulda smoked till about 3days before the test...

Let us know how ya make out man.
