Most pheromone ptudocrs are not bogus. Although there are a few that are total scams and a couple of those are very aggresively marketed.Basically, anything sold by Androtics Direct or Love Scent is legit. The better pheromone ptudocrs are extremely effective. If you go to the Pherotalk forum and browse around the various posts, you'll see just how effective they are.Natural pheromones, I'm not so sure how big a role they play. Obviously, there is a strong mechanism in place for reaction to pheromones in humans, but how specific it is in matching up compatible people, I have very little experience with.There are companies that will do genetic testing on this for you and hook you up with people who you should have strong chemistry with based on this. There is some scientific evidence to suggest this works but I haven't seen it catch on much in the US. The company ScientificMatch runs a very expensive dating service based on this that is pretty much limited to the greater Boston area of the US. It'll cost you about two thousand bucks to join.A much cheaper alternative is Genepartner. They will test you for about $ 100 and then charge you a small fee for the number of times you check your compatibility with someone elses. However, they do NOT maintain a dating site and most people who use this service are from europe. Some groups on Facebook are starting to form of people who use this service. The person posts their Genepartner code on their pofile page and you can take it to the Genepartner website and check their compatibility with you before sending them an email or something.
