Heya Matt
Maybe it just wasn’t working in your testing environments, or with the humans you were around, or some other factor?
Gosh, I briefly tested it out with a friend some weeks (maybe months now) ago, and OUR results were just flabberghasting.
I usually go out as a “wingman” to spot hits for my friends, while they sport pheromixes of all varieties. Pheromoning always works better in a buddy system, because there are a few different perspectives involved. Four eyes are better than two!
Back to MX177.
This one was pretty friggin wild. Our reactions were blatant and ridiculous.
There was this two set of girls talking talking talking near the refrigerated section. Moments later, one of them was bobbing her head up and down with her mouth arched in an O… much ilke she was sucking a… lollipop… …
Other girls touched their boobs, spilled our of their shirts, licked their lips, and caused all sorts of sexual frenzy. I saw one lady kind of grinding herself against a mid-store pedestal. Lots of overts. I can’t even remember them all, and I don’t have my notes from the day in front of me. I can update later when I get them.
I haven’t heard a lot of chatter on MX177-MX178, except from you, Mattiloo. Did everyone else forget about that one?? 
Oh yeah! And what were your application points; how much were you wearing; and where did you go?
