Oh I commend you on your efforts. Nice pics to boot. I just think many are not posting because nothing was proven or debunked. Perhaps others will step up to further test the theory. Sure the deer are sniffin, it's something new, atleast we do know from your efforts that it does not spoke them.
Take a walk on a seldom used trail with a plug, post a trail cam along the way and see if activity picks up, scent should last for what 2 days?
Make a few mock scraps in the same general area, one with male urine, one with otc scent, one with the female urine(maybe even one two weeks prior to cycle and one on cycle). See if it can be determined if one gets hit harder than the others.
We are of course different species, but I feel the pheromones will be close enough, that in a week or two, even the slightest possability of a gal in estrous will stir up the already randy buck. I would think if it works, using it as a drag "rag", then being hung up would provide the most benefit.
If it works, next year we can experiment on the otc pheromones and avoid the whole bloody mess.
