Hi Lauren, welcome to Pherotalk! 
The default scent is Neroli (I believe there’s also a slight blend of essential oils? I may be wrong) in a 6% fragrance because it acts as a binder for the mones and is highly diffusive. Personally, I don’t like it, because it smells too strong and masculine on me, but others here love it or find it not so bad. It is fairly co-operative, I’ll give it that 
, so if you don’t mind the scent blending in with your perfume, just spray straight after application. Or, you can wait for the 10~20 minute dry down, when it’s less noticeable, and put on your perfume then. You should know, though, that putting on perfume or lotion or other scents will probably affect the diffusion of the pheromones. Not necessarily lose its effectiveness, but you might want to run a few forum searches on this topic. Anyway, once you start getting serious with the reporting - MXs, and Putatives and such - it is recommended that you go and test with just that product alone, at least at first. You can also get custom fragrances on some of the 30ml bottles - Grapefruit, Cookie, Chocolatini, Coconut Vanilla, etc.

As for application points - try hair, front/sides/back of neck, inner crook of your elbows, wrists, behind knees, armpits, top of head - the possibilities are endless, so you need to find out what works best for you. Pulse points are generally a good idea, though.
Either way, I hope you have a blast! Please do let us know all about your experiences, and I invite you to come and post in the Women’s forum in particular. Good luck, and I hope to see you around.
