Can you give us a bit more info about where you were geting hits and from what sort of age range?
TBH, the best way to assess any phero is to follow Steve’s Sweet Spot guide to establish basic doses for your typical forms of social interaction. That way you eliminate as many variables as possible and TBH, where pheros are concerned, there are a lot. Especially with overt none - which will get you ignored/ghosted/trigger negative responses in some situations but get exactly the opposite in others - even with the same people!
Its not all entirely concerned with quantity and diffusion - In some situations a tiny amount can work wonders and then when inhibitions are lowered, you might find you can use a much higher dose effectively. At 37, you have a much wider dose range to operate within compared to a younger guy. Then there is the matter of socials/none moderators - which depending on the ages of your targets, can be every bit as important in provoking feelings as piling-on the none.
