Assume I am wearing Instant Openness or Instant Shine, how will people identify me as the open and approacheable type? I mean if Joe is standing beside me, would others mistakenly talk to Joe instead? If I walked around a lot, and my pheromones were spread across the entire room, what would happen then?
If you are indoors, your pheros will probably spread across the room, specially if it is small (say a car, or a bedroom) independently if you move or not, fortunately or unfortunately it will end affecting every people inside (some people will be more affected than others depending of the quantity of exposure, their ascendancy, if they’re drunk, etc). This is a good thing IMHO although it depends on what effects you desire.
Anyway if you are moving, normally people is more capable of guessing who is really the source of the pheromones, specially if you go near and away of your target (indoors). Take in count that although room is propably full of phero traces, you are the source and pheros are much more intense on you (this sounded like some StarWars freak comment 
)
Outdoors or in very big rooms, clubs, or charged ambients i’ve found better to be near your objective anyway
The most important part to success with pheromones is living up to the pheromone signature you put out through your actions and how you present yourself. There needs to be some level of congruency between the pheromone signature you put out, and how you interact with people. If you spray on pheromones and don’t play an active role in socializing and otherwise facilitating the reception of their effects, they may go unnoticed, or may even be attributed to someone who is playing a more visible role. Pheromones seem to work more effectively as mood/perception enhancers, not creators…As in people will more readily notice how you look, how you carry yourself, and your behavior. Once you have their attention and they notice you, they more obviously detect the pheromones, and enhance the initial impressions they had of you.
Pheromones can usually be pinpointed to a central source however, even when the pheromone sillage wafts around a crowded room. Though the pheromones may travel around the room in different areas around different people, the pheromones will pool more heavily around the wearer as the most concentrated source of the pheromones. Picture a crowded restaurant with all sorts of aromatic stimuli. Somewhere in the restaurant a dish smells tasty to you and captures your attention…eventually you’re able to pinpoint the source of smell based on where the scent is most concentrated. I believe pheromones work in a highly similar fashion, although again how people perceive the effects and where they are coming from a largely a manner of your own behavior.
I have found that walking around a room can help diffuse the pheromones to a large number of people present… 
i’ve had this happen to me a couple of times. those darn mones stealers~! lol 
What if I mixed pheromones with my own sweat? Such as spraying pheromones into my armpits, then reapplying them to my face and neck areas. Would that make my pheromones my own and distinguishable from others?
that’s the old pit trick (without reapplying to face/neck though)…
I tried it once a few weeks ago! My natural none production must have increased after I did that..
Phoenix, why do you say your none production has increased since you used the pit trick? Have you noticed more sweating since that? This happened to me first time i used -none products but in two days it became normal again.
Yes, I noticed more sweating in that particular arm pit for a few days - 2 or 3 as you say. Three weeks later it’s back to normal as regards sweating - probably -none is normal too..
