KW, have you ever used the dilution method successfully?

Also, would 4 or 5 days of intense exercise really help? Since my test is probaly next Friday, I could get at least 4 days if it would help. I know everyone is different, but I am paranoid as hell as this is an important job for my family.

I am prepared to use the substitution method if necessary, although I would feel more comfortable peeing myself. I bought some drinks a couple of years ago for a life insurance physical and it came back too diluted so I had to pee again. Is the threshold for a life insurance test higher than it would be for a preemployment screen.

That study about the detection window being shorter than previously thought is apparently bs.
