I read the threads here and bought quickfix 4.0 online and it was simple to use, easy to hide in my underwear and I passed no problem. Its synthetic urine and its worked for quite a few people on this site. It pisses me off when you ask for advice and you get people who tell you to quit smoking pot. I quit smoking for over a month and still didn't pass the home test so thats why I bought quickfix and got it for $20.00 a bottle online. Take care, hope you pass your next test.
