Actully drinking just the gartorade works. I've passed to test using that method..not sure if its just drinking all the liquid that works or the certo mixed with it..but I'm possitive that the gatorade and certo works ..not sure why you'd need to take the asprin with it,,,I didnt and still paased..
JustanotherMary Reviewed by JustanotherMary on . Certo Method..Help Please! I'm getting drug tested tommorow and I am wondering if the certo method would work on such short notice. I am gunna get a 32 oz gatorade and mix it with pack of Certo. I am gunna do that about an hour before my test. Im then going to urinate twice or so before the test. Then I am going to take about 1250 mg's of asprin. Before the test I am going to drink 2 cups of water. Please give me some tips or share stories..Thanks. Rating: 5
