Best store bought stuff I've used is James Valley, Scrape Jell. I've used it off and on for 3 seasons and have yet to have a negative reaction by a deer. I put it on twigs and branches about knee high. Friday AM I had a 6pt running from branch to branch sniffing it. First year I used it I'm sure it contributed to the death of a monster 10 pt.
When I use scent I also use James Valley. I think you can only order it and you need to do it before the season since they used to run out of it. I have seen a buck come off of a doe he was trailing to come to the scent. Keep it refrigerated and it will last awhile.
