Which pheromone to get my ex back?

I agree with all of the above, one thing I will add though is that Molecule F (TAF) has a great ability to have people drop a preconception about you.

I spent some time in Japan where there are bars that notoriously disallow ‘gaijin’ (foreigners). After having gone to several bars pheromone’d up (A314 + 3 sprays of 12.5 mcg TAF) I told some other friends and their jaws dropped. They barely made it to the door before being sent away at a few of these specific bars.

So there are ways around preconceptions - however, in this case it seems really tough.

I don’t want to sell you something without you understanding that pheromones are not 100% magic. People still have free will, despite what you might read in some marketing.

People’s will and prejudice are powerful. But if I had to recommend anything to try, it would be TAF and maybe Instant Openness/Instant Honesty mix. (EDIT: Come to think of it, maybe even better TAF + Instant Gentleman - much more what you need than IH/IO)
