Hi Alison - Welcome to Pherotalk! 
Well, hopefully you will find you have found a whone new world of social, sexual and status enhancing products to interest you here.
Also, you will be glad to know that virtually all of them are reasonably compatible with practical vegetarian and vegan values (hi-ethics people may have problems based on more ephemeral concepts). OTOH, the only one you need to avoid is MEO-EST and I think that all the musks used in ADs scents are now plant based. These threads may explain more:
If you can give us a little more info about yourself and how you want to begin trying pheros, we can maybe offer better advice and you will earn a GC to help you lose your scepticism. Have a read here:

In the meantime, if you want to plunge straight-in and try pheros for yourself, Instant Shine or IO are good unisex products with obvious effects, whilst TUTH is designed to help enhance passion in established sexual relationships. Well-worth it IME!
