I don’t know much about women Pheromones, but they have a section for discussing women pheromones with other women here WOMEN’s Pheromone Advice, Tips and Tricks at PheromoneTalk.com
Also in the womens section, look at the sticky threads at the top. Especially this one What pheromones can and can't do: realistic expectations for newcomers
That will pretty much answer what they can and cannot do.
Hope this helps.
