Hey ope1, welcome to pherotalk
Pay no attention to what your associates say. It will be your obvious advantage 
I haven’t had any experience with p74 but I hear that a314 is the business sales pheromone. It’s a bit pricey. Instant honestly can also work in your favor too as it helps establish rapport and trust in people, it’s also a bit pricey but you can always go for the togo bottles to test them both out and see which one you like (yes both a314 and IH come in togo bottles).
I’m slightly confused however by the wording, did you already purchase the newbie kit?
Edit: forgive me I just read your thread post- a314 is included as well as IH in the killer pheromone newbie kit. Get testing!
If you have any questions go ahead and ask them, we’re happy to help you!
However, first thing is first, once you get them, you need to find your sweet spot
Before you give up IS to your son, be sure to test it for yourself. You might find that you like it too much to give it up
