@anamur-- I think that pheromone colognes and perfumes can be really beneficial in different ways. But since we don't know enough about pheromones in general, using it does carry some risks and it works differently for different people. I have a friend who tried pheromone cologne to attract the opposite sex and claimed that it did exactly the opposite for him.
But I've also heard some really great things about them and the ones that are said to improve mood interests me the most. Apparently this cologne changes the mood of people around us positively. If it's true, that's really cool.
I wonder if pheromone cologne could work on the person wearing it too? For example, if someone is in a depression, could they come out of it by wearing the mood-boosting pheromone cologne all the time? That would be the best anti-depression drug ever!
