Waiting is the tough part! From everything I have read it takes 24-72 hours for the creatine to metabolize into your system and become creatinine. The last scoop I don't think would have done anything for that. One of the more seasoned gents should correct me if i'm wrong. From everything I have seen if you will pass the home test consistently with your first morning void you should have no problem! Thank you for the advice I will try that.
