I’ve been doing a lot of experimenting in this regard, because I actually have ADHD and take those meds. But then again, because I actually have it, I’m simply at a baseline when I do take them. 
Ultimately, as people have said on related threads (and feel free to search on it, there are some interesting discussions) pheromones aren’t going to be the best thing for this. There are supplements and the like that will help far more.
That said…personally, I’m finding P95 to be handy. P92 kind of was, except when it wore off it was even worse than before. It was great until that though. Lots of people report good luck with P102 in that regard, personally I don’t have enhancement of focus but your mileage may vary. TAF is supposed to be great for that…but it’s not really available for non reporting users unless you want to pay a lot of money. One day, one day…
