Ok, after I took my test and passed I was shredding the sheet from the Lab that had the test on it. I input the number SAP 5-50 W/NIT in google and did a search. Came up with this website and saw some posts from some people talking about Certo... that just really don't know the full facts or HOW to use it properly to pass. I would say off the top of my head I have passed probably a couple dozen or more tests using a Certo formula I have come up with. I have even gone as far as smoking on the way to the test using this method. All the ingredients cost about 5 bucks total. And for those non believers out there... my tests NEVER come back saying that my urine is is too diluted with water or ANYTHING else. Trick is .... throwing in some good nutrients on that last glass fluid (hint: MILK) you intake before you P in the cup... (hint: protein drinks work wonders). So... again... for those of you who say the "C" method is a myth (which I read quite a bit....) I say "whatever... you don't know what your talking about. I have been using this method for over 10 years now"
