Thats definitely good that your curious about pheremones.They are fun things to play with.They work really well though they are best paired with good social skills since they are more for setting the mood.They help a lot though particularly if your shy or want a confidence boost.This link is pretty good for explaining what they can do.A lot of the effects can be pretty subtle though and you will have to keep an eye out to notice hits.
Pagodeiro and xpx have already given you good advice on products so you should definitely get the 25$ gift certificate by writing a bit more about your personality,social skills and where you want to use them so that you can pick up some to-go’s pretty much risk free. Anyways,theres only 4 products so you could get them all in to-go’s and see what works out best for you since everybodies different.(^^)IO,IS and instant sexiness are probably a good starter set for you like xpx said.You should read the two stickies below as they contain good starter information before making your first purchase as well as the one pagodeiro posted.All the best and hope things go well for you.Im sure you will have fun here and hope to hear from you again soon(^^)
