Lawrence, I think that might work. The pheromones you had on it would probably effect her more emotionally, thus placing a stronger memory on your number. But if you were to use a pheromone that didn’t have much scent to it, then she might not be able to smell it unless she places it up close in a crowded bar. So you would need a scent to draw her into it. As suggested above Ammo will probably do the trick.
I think the most flexible, and a possibly more effective solution is to spray whatever cologne/smell that you want her to associate the memory of you with. Then, over the cologne, spray whatever pheromone mix you want. You could use different mixes to effect the recipient in certain manners. A letter sprayed with TAA will be very different than a letter sprayed with lots and lots of pure -none.
Baldman, you experienced first hand how powerful the associate between smell and memory is.
So, rather than trying to strengthen an already strong association, strengthen the memory of the event instead. At the same time, give the recipient a distinct smell to associate the memory with.
Ammo is probably the easiest way to do that. But it’s limited in utility. What if you want to expose the recipient a -none free mix. More importantly, what if you want the recipient to associate the memory with your signature scent? If Ammo’s yours then great. But some might prefer a different scent.
Also, as I said above, different pheromones would result in different impressions. Let’s say you were a boxer, I guess you could send a letter or whatever and put some dark smelling cologne on it with lots of -none for intimidation. That could possibly intimidate him slightly, maybe just makes him really angry, I dunno. But either way, it would be tied to the smell and if you were to wear that same scent during the fight, perhaps it would invoke a similar reaction.
Anyways, I think it could be kind of fun if you really got into it.
