Okay, I´ll argue the other side. But first I must agree, there is no reliable way to trick an animals nose.
you can view the sensitivity of an animals nose (or the electro'chemical signal sent to the brain) as the inverse of a houses electrical breaker system. So what do I mean, I mean that a curcit breaker is designed to trip when to much power is being drawn through the system. In the case of animals, they need to detect a minimal amount of scent before a signal is sent to their brain. Obviously that minimal amount depends on the type of animal, but we´re talking parts per million. In'other'words, there is a threshold there, that needs to be met before an animals brain receives a message about the scent it´s picked up.
With that in mind, in theory, it is possible to reduce your scent to levels low enough that an animal does not receive enough scent (parts per million proccessed) to triger a signal to the brain, resulting in the animal being unaware of the human odor, or any odor that is insufficent to result in meeting the threshold and triggering a signal to their brain.
The issue is that we cannot control the odor producing process of our bodies, all we can do is limit it. If you use those mirical products (as they have been caled) in camp, and take a 2 mile hike, well your going to sweat up, and, well stink. You can brush your teeth, but you don´t necessarly want to be putting out minty freshness in an area with no mint. Yoiu can however use baking soda. But as has been stated, your not going to eliminate all your scent. The big question here is can you reduce it enough to make a difference. If you cary those scent eliminating sprays into the field and reapply, then maybe you can. From my experance playing around with many different products, it can make a difference. However, other than using a trained tracking dog (which I have not done) I have no idea of how you would test this. But in short, you´d be a fol to not play the wind as much as possible, with or without these type of products.
