It’s not that it doesn’t work in your age group, I think it’s just that at your age your body is already producing a lot of pheromones and the people you tend to hang around might be more susceptible to their effects, so it’s easier to overdose with certain products. I think it would be fairer to say they’re more difficult to use properly in your age range.
The “ghosting effect” of not being noticed you experienced could have been a -none overdose or something, or maybe just that the expectations you had for the pheromones going in were a bit on the high side. I know it’s easy to get caught up in all the seemingly unreal stories that get reported around here, but there really is a hard limit to what they can do, and I would highly recommend taking a look at this thread if you haven’t already.
I would just keep experimenting. Try them out in different places. Train yourself to look for more subtle hints of reactions, and don’t wear it every single time you go out or it may be difficult to maintain a basis of comparison. Also, I would go with the recommendation of trying out something like Instant Openness, even if you’re not shy. You can even get a $25 gift card to order a to go bottle or two if you post a thread following the instructions in the introductory forum of this message board. The social pheromones are much easier to goof around with, and you don’t really have to worry about overdosing.
