Hi Mark & nice to have you as a member of Pherotalk 
I see you want to open up and make it easier for you to talk to people. The best recommendations for this will be Instant openness & Instant Shine. For Instant openness, it will make the user more easier to have a conservation & become more chattier than usual with others & for Instant Shine, it will increase the confidence in you in approaching anyone especially girls.
And yes like I agreed with what Mockingbird has said add AMMO to Instant openness for girls to be attracted a little more & interested on you. for more detailed info on the pheros here click on this link> Mens Pheromone Guide revised 6/15
I hope i managed to help you out See you
