The best thing you can do is start your own thread in the Intro Forum, with some more detail about yourself, the choice of places you have to use pheros and the sort of girls you are hoping to influence.
That way we can give better advice and you get the GC to help start trying stuff out.
However, I’ll say right now that there is no phero that will make anyone fall in love with you by itself but there are many that will help enhance and support your own attractive qualities and personality aspects - Which help make your task all the easier. Then there are pheros that enhance the comfort and feeling good aspects of being around you and that help promote the sort of yearning/wanting mood that can help love along - but none of these are quick fixes, you have to do the work and let them do theirs.
