Hello Starfox & nice to have you as a member of Pherotalk 
Ok so i have seen two of my phero buddies have tell you everything they know. Ok first of all glad you found this forum & your keen interest in pheros here And yes the pheros here are the real deal & they have been researched & tested so don’t worry about it.
Anyway so i see you are a teacher of an adult school, yes i would recommended A314 & add Instant Openness or Instant shine to it but i leave it to you to decide. Don’t be surprised when you see the results 
Here is a link about A314 & the instants with the other pheros here> mens pheromone guide
See you
