THC Test, Faint Lines...

I thought I had two months to prepare for 'the-test'. Found out last week that I have to go this Monday. I'll be 30-days, no chronic. I'm 6'2" and 250 lbs a sizeable guy. Very little excercise but I do take an assortment of vitamins and drink 32oz-64oz of water per day five days a week. Here's the deal. I bought several of the TCH essays tests. Drop two drops of piss in the hole wait five minutes and two lines your good, one your bad. I've been testing myself every week for the last month. Results:
Week1: Control Line visible, test line invisible
Week2: Control Line visible, test line faint
Week3: Control Line visible, test line faint
Week4: Control Line visible, test line faint but coming on stronger.

After reading this board for hours I find out that a faint line is a 'good' negative line. I read in the test kit instructions from the manufacturer approx the same thing.

Just to be sure I ordered some urine and recieved it today. I tested this stuff to see and the results were particularily instersting. The control was visible and the test line was just as visible, no faint line here.

What do you guys think? Am I good or should I substitute? Just a little nervous about getting caught substituting or having the wrong temp or something.

Does a faint line really indicate a negative? This is not a test from the drugstore but one from an internet company.

What would you do, go lone or fill the rubber?
:confused:

Well shortly after writing the original post I had drank 2 additional liters of water. I decided to re-test myself after about three pisses. Wouldn't you know the test now has a DARK beautiful purple line :D on the test as well as the control. My test is Tuesday so here's what I'm going to do:

1) Keep drinking 2-4 liters of water per day
2) I started creatine loading yesterday, I'll keep that up
3) I already take several vitamins, including B-12 so that will keep my color healthy
4) I'll drink plenty and check myself before I go test, to make sure I'm good to go.

I think after 30 days I'm right on the hairy edge of 50ng. So adding a little extra water will put me well below the mark.

Thank god I don't have to substitute. Although I was staring to prepare myself tonight. I was going to utilize two avenues for substitution. I bougth the human urine with the 'pouch' but was uncomfortable that they might ask me to lift my shirt. I bought a digital therm, thanks to N2, some rubbers and a 2 oz (60ml) Johnson&Johnson shampoo bottle. I was going to practice moving, walking and generally keeping the temp up. My piss comes out at 99 deg. So this was what I was shooting for. With the jergens bottle I was able to keep it at 98 deg stuck in my scrotum. The same with the rubber.

Thanks for the tips and all the previous forum info...

jesus, that is a shit load of work for a test.........
