What kind of results are you looking for? A lot of “hits” are actually subtle changes in behavior that are not always as obvious as some of the ones you might read about on here.
First you have to have a good sense of how people react to you under normal circumstances. Friends, family, coworkers, classmates etc.
Strangers…well for them you just have to kinda get a sense of how a typical stranger reacts to you on an average day.
Then depending on the products, you may notice different kinds of hits.
That gives a pretty good list of how certain pheromones might get certain results. I figure it helps if you know what you’re looking for to begin with.
