I have wondered if the pheromone chips and such worked. I would not personally want to use them. I have gotten a sniff of some chips. They smelled like the Chimp enclosure at the zoo. That strong vingery urine smell.
With so much not known about these big guys. I find it interesting to find out what has actually been tried and or observed to have worked or not worked.
I know there was/is a discussion on pheromones being something that may cause the panic or fright feelings in humans while in the presence of Sas.
I wonder if this is a contributor to the fight or flight factor in many encounters.
The "chips" you mention may well be simply chimp urine, et. al....the stuff we were using was human pheronome.
