I got the perfume, its oil-based in a rollerball and has lots of smells I find yummy, vanilla, rose, frankincense etc - if memory serves - and I really liked it so I slopped some on and wore it to work. (Bear in mind, I had no idea about the pheromones or, as it transpired copulins, at this point. In fact I hadn’t even hear of copulins.)
I’ve worked at the same place for a while, and so the men there don’t seem to really notice me - at least not as a woman - anymore.
Well, three of them very obviously and very noticeably deliberately looked me up and down. You know the way men do, from the top of your head, to your toes, and back up again. 
Which I thought very odd. Not only that but they were very chatty and friendly, as were many of the others.
Also, I got the comment. “There is a lovely smell in the corridor. It’s your perfume.”
So, after such a good compliment on my new perfume, when I got home I phoned my friend to ask where she got it.
She said ebay and then emailed me the url. So, I looked it up and it is listed as a pheromone and copulin formulated perfume. Which when I thought back explained rather a lot!
I wasted no time in ordering another bottle.
I don’t know what type of pheromone, or how concentrated or anything. It can’t be really choc-a-bloc full of pheromones as it was/ is pretty cheap considering it is oil-based and a little seems to go a heck of a long way.
It does seem to do something though - and between ourselves - I think I could get used to the flirting
