Pheromones have proven effect.They affect you partners senses and you will see the result almost immediately.
But there are many peolpe, that say "pheromones don't works".Why is that? First of all many of them have never used any kind of pheromones in perfume or cologne. That is true, but it is not the main reason.The main reason is that there are many companies that produce non-effective ones or in some cases they even see you ordinary parfumes(in it there are not secret scent).They make millions of cash for that but people are not satisfied.
How can you understand is it a fake or not? Easy.If it is not fake with original scent you will see immediate results. Tf you don't see any changes on your first date - you won't see ever with that fake "pheromone scents".
And don't say pheromones don't works, because they works.You just have used fake one.
Use only big authority companies when you buy pheromones in perfume.
