I've been experimenting with pheros, but generally haven't found the right dosage(s) for the kind of reactions that other women seem to get. I received a sample of PheroGirl Cougar in my order, which was interesting because I hesitated to order it because I am not all that fond of of grapefruit. Several of you wonderful ladies had advised me to try it anyway, so with the sample I did. For the first time I got a reaction! Standing in the line at Starbucks, the young man in front of me swung around and struck up a conversation. I was so startled -- that never happens to me, especially as I am old enough to be his mother. I'd applied a total of 6 drops behind ears, on each side of the neck, in my cleavage and one drop split between my wrists. I'm now ordering a full-size bottle. I still can't believe that reaction and want to try it again.
