Well, I hope you will find this one of the best phero sites around and that the products are superb.
Also remember that not all pheros work for all people and that responses to pheros vary depending on individual and social situations, so do give them a good try in all aspects of your life.
To start, have a good read of these threads:
Which will cover all the basics on choosing and using pheros effectively.
Your initial choice of Ammo and IO is good - They will certainly contribute to the confidence and icebreaking you need but I would also suggest you look at Instant Shine - Which is a great uplifting/social/socially confident and feelgood mix - It helps make you appear great to be around and will if you demonstrate the behaviours to back it up. It is also usable in almost any situation you can think of as it does not contain none, which can have pitfalls in some situations. Although Ammo is well balanced and normally avoids most of them.
