You are correct, you cannot totally eliminate your human odor, but you can reduce it. Most whitetails accept a certain amount of human odor. If they didn't, they be on the run 24/7 unless they live in such a dense area that humans don't exist. In my hunting area, there are humans 360 degrees around the woods. If they didn't accept some human odor, why would they live there. The key to is to reduce your odor to an acceptable level so when they do wind you, they think your not as close as you really are. If Scentlok or Scent Blocker and Scent Killer helps me to that, which it has, I'm all for it.
