This is a great question NightHawk. Glad you asked.
I don’t have scientific proof behind this, but I have come to understand it through personal use.
The pheromones have an average life span of about 4 hours on skin before they are broken down and dissapated. When I first started wearing my pheromones, the same ones you wear + more, I could smell that musky scent almost the entire time. I got hits and IOI’s from the ladies constantly the entire time. As I progressed in my use of phero’s I too noticed that the musky scent became less and less. The phero-signature however continued to result in IOI’s from the ladies so I knew full well they were working.
The way this is explained in other posts is that your smell senses become acclimated to the smell and eventually blocks out the smell, not the actual phero’s though. It’s like working in a very smelly environment. After a few days you get acquanted to the smell and it is more bearable to you. A new person comes around and says PU this stinks, how can you stand it. You reply, you get used to it.
Same concept, you get used to it. Yesterday was the first day in 3 weeks I didn’t wear any pheromones. Today when I applied my beloved little smelly friends I can smell that musky smell for about 3 hours now.
It’s not the smell of the pheromones that count though it’s the chemical reaction in the brain that matters.
Great question and check out this post *(I smell my Donkeys shit 1 mile away)
It explains this theory better than I can.*
