I can remember reading something about bucks being able to determine the dominance of another " deer" by the testoterone levels in the urine they smell. So I don' t think a 4-years olds urine will do anything at all. It will probably even come across as an immature deer' s urine. However, if you were to take a leak near your stand it may put bucks on alert that there is another dominant " deer" in the area - and that' s what drives them nuts.

Welcome aboard!
