pheromones enhance who you already are. They dont manipulate anyone. People will not do anything against there will. They will not change who you are in any way.
Here this may help you understand a little more about what they can and cant do.
They will give you a edge and make socialization alot easier and fun.
With people who know you well it takes more exposures for them to react to some pheromones because they have preconceived notions about you but they do come around.
Think of them as just another tool in attraction. They wont do all the work for you but they will help a great deal.
