Do you really believe the people who bottle Code Blue have enough live deer yet alone doe that are standing in estrous meaning at the peak of their cycle to bottle enough lure for millions of hunters to use. I am not saying some maybe deer lure but. only platinum standing estrous in a bottle. If you must use deer lure by the average priced stuff and save a little money. or you could just make sure you are hunting does not bucks when the pre-rut or rut comes in.
