Hi DatGuy, welcome to the forums!
Not silly at all! The way I found pheromones was through the movie ‘Oceans 13’ where Matt Damon used some kind of irresistible phero-parfume to make women crazy.. So I’d probably say that your Batman-thing has a more scientific/not so naive reason to look up mones 
As for the pheromones:
Ammo and TUTH are both great for attraction and confidence, but if you are looking for an opener, I’d probably suggest Instant Openess and/or Instant Shine -
Instant Openess is known to make people slightly more talky, and Instant Shine is a great confidence booster, making you the centre of the party.
Combined, the two would make a great opener, I could imagine.
Regarding placement:
