Well, this seems somewhere to start chiping-in my experience. 
Alter Ego, with an extra of alcohol-based Androstenone spray was by far my most successful combination of pheromones before I found Androtics.
Initially, I had been using the Androstenone spray on its own, in varying amounts and locations for. It had been ok but not greatly appealing to women in my own age range - although it had sparked a number of previously reserved women into very intimate/sexual conversations. Younger women were a different matter - They seemed to like it a lot even though I was somewhat wary of them.
Anyway, I first wore the combination on an evening date with a woman in her late 30s. We have been out a good few times now and are pretty relaxed with each other.
Two drops of Alter Ego - one to the forearms before rubbing together and another to the neck, followed by three sprays of Androstenone to my clothing, one on each shoulder and one mid-chest.
It didn’t seem to go very well, she sat close but was rather morose and untalkative but we had a pleasant enough evening and she readilly agreed to an activity at the weekend. The difference there was that I used three drops of Alter Ego, two to the neck and one for the forearms. Andrestonone was the same.
That day went by ok but again, on the drive back, she became very quiet and spent most of the journey fiddling with her phone. We dropped our pal off and headed to her’s for a coffee where various things came-up in conversation and eventually we got on to the subject of how quiet she’d been. Then she dropped the bombshell.
“Sorry, but on Thursday, I was just so horny I really didn’t know what to do, it was too soon”
“And today, coming back in the car, I was just so wishing that S---- wasn’t there - I just really wanted you to find a quiet place to park the car so we could do things”
After that revelation I went and uncorked a bottle of wine and we did do things, plenty of things!
