got a dog?
9.1.3 Catheterization:
First void your bladder as you would with injection. Run a thin plastic tube to the bladder. (Males must insert the tube into the opening of the penis, go through the urethra and into the bladder.) Catheterization done on females is not as unpleasant as it is for males. Then inject the clean urine into the bladder via catheter. Catheterization is less painful, safer, and more effective. Infection is still possible.
9.2 Where to get clean urine.
9.2.1 Urine from a donor:
You can substitute someone else's urine. Ask your urine donor (hopefully a friend you can trust) what drugs they've taken in the last month. They may have taken a false positive (or a true positive for that matter). Before the test, the examiner will likely ask you to list everything you've taken. If the urine ages beyond 18 hours, deterioration becomes noticable and the lab may suspect something.
9.2.2 Powdered urine: If you don't trust your friend's sample, or don't have any clean friends, you can get powdered urine from Martha Butterfield-Jay Foundation. It's produced by Byrd Labs, and supposedly works perfectly; however, I got MBJF's powdered urine, and it did not specify the age or gender of the original sample. Powdered urine must be prepared ahead of time. If there is a period of time that you are clean, you can make powdered urine from your own supply.
9.2.2.1 Making your own powdered urine:
Urinate in a glass container. Let it evaporate. Then scrape the inside for the concentrate. Just mix it with water before the test, and the sample will have the correct specific gravity, pH, color, etc.
9.2.3 Dog urine:
I heard from Dr. Grow that dog urine (of all things) can be substituted, and will pass the test! However, I don't know how an age, gender, pH, or creatinine test would result. Someone was able to use dog urine for several months to pass the test. This subsection assumes you have a clean dog. I know my dog's urine wouldn't pass; he eats more weed than humans do. It would make more sense to use human urine, but dog urine provides a workable substitution in an emergency.
