i have always been sceptic aboutthem working in humans. as far as animlas def. works. just look at deer for example. All over the country around now pre rutt and rutt shall be taking place and you see tons of deer and see tons of deer being killed by cars, trucks etc. and big bucks crushed to boot. the reason is because of the pheromones giving off by the doe which causes the buck to go absolutely ape ****. now if we could just get it to work on women like that we would be set!!! lol but women have a more complex mind the deer so maybe that is the difference.
