bmorris, If you want a copy of this test, I would contact Virginia Tech directly and ask for their study. If I had a copy handy, I would happily email you one. I do know right after it was finished, Natural Predator, the company that makes Tru Carbon was anxious to mention it on their website. It was not funded by any outside source, that I'm sure of.
As far as the dogs goes, I don't doubt one bit that they didn't detect human scent. Blood hounds are incredible animals! So are deer! It's just too bad we can't ask them specific questions regarding human scent and how hard it is for them to detect it under these testing conditions. I also agree with you regarding the test conditions and the applications of these products. My point is this: Activated carbon works extremely well under the conditions most hunters are under and when it is applied as instructed, there is no other product commercially available known to reduce human scent as effectively.
Under the conditions I've tested them under, I have also found no other product/chemical'formula that allows me to elude mature whitetails up close. In some of our tests, I've had members of our research team sit in a linear fashion along a heavily traveled deer route. Each and every one of us had a different type of scent control product. With me wearing the activated ladened Ghillie suit, I have had spoked deer run from one person using an off the shelf scent control product with to within 10 yards of me for safety. I've had bedded deer in front of me for hours, while I was on the ground, with no sign of distress. I can't tell you how many deer over the years I am in close contact with that have no idea how close they are to me. The biggest change came when I switched from a water based product to an activated carbon one. As a side not, I even made my own scent spray that works really well but it just isn't effective as the carbon.
As far as application goes, if a person doesn't shower or jumps into the woods right after work and expects his body to not smell or even better yet, expects his scent control product to perform flawlessly, he's in for a big surprise. Nevertheless, I've placed an once of raw skunk perfume in my hand and have poured activated carbon right on top of it only to witness the smell to completely go away (by my standards, meaning that I could not smell a trace of it). That is proof enough for me that it does work but obviously not sure to what level. When using scent control for deer hunting, one must also use everything in his/her power to mask their scent.
