Yes take the creatine now. It takes 2-3 days for the creatine to turn into creatinine which is what the co. will test for. Also load up on red meat if you can to take in more creatine. Also definitely test your first void since this will be your best indicator. If you can pass your first void then you should be fine and only have to do a minor dilute with about 32oz of gatorade.

I know this can be anxiety producing. I have been clean for 17 days now as I am interviewing with a few companies and I do not know which ones will be testing. I however do not have any anxiety because my last three tests on my first voids came up negative. I am fine and now just need to worry about doing well on my interviews. Good luck to you.
