I have never had any luck with commercially produced so called "attractants" ... Tink's. Code Blue, Harmon's ... none of these. I tried a few over the years, but to no avail. I quit trying years ago.

I do use tarsals and urine that I collect from deer I or my buds kill, using these mostly as a trail cover scent (drag rag) or "stinking up" a mock scrape. I have had a few decent bucks come in to investigate these scrape or flemming the drag trail, but not many. I think that this has been more of a matter of couriosity of a buck that was easing by close and downwind .... rather than "attracting" a buck from any considerable distance.
