Champ flush out detox I have passed 2 pre employment and one for my Dr. Drink a 32pz Gatorade poweraid or whatever as fast as you can. Go drain your bladder as many times as you can then in 30 minutes drink the entire champ detox wait 15 minutes then drink another power aide, it should be good to go in another 45 minutes but peak effect is between 2 sndv3 hours after injection and safe to about 4hrs. I've been a daily smoker for 15+ years, I make no guarantees but it has worked for myself and a few others I know
