I did mine the night before approx. 6:00pm and took the test at 8:00am the following morning. But keep in mind all bodies are different. Im 5'10'' tall and weighs 185lb. I also started taking a vitimen called mens source wich was recomended by the person at GNC one week prior to the test. Good luck
