Can you grow more once you stopped growing?

I am 18 male and I'm only 5'5", I have completely stopped growing now and even my dad is those 2-3" taller, I maintain a healthy diet and exercise on daily basis. Is there anyway I can grow? Are there any exercises that will elongate my body, also I have seen many diet supplements that suppose to make you grow, do these work? If they do work, which brand pills you recommend me taking, what are the side effects?
