it's not gonna work if you're socially isolated and don't meet women except for brief moments at the cash register

But they do work.science proves it.
pherotruth,houseofpheromones,the athena insitute etc all have scientific research proving this.
what you ideally would do is either use a intimacy pheromone and love pheromone over a sexual one,love is more powerful than lust.
you would use it at work or a social setting like a bar with frequent visitors,a place where you have contact with the same women.
and you would make them fall in love with you,imprint emotions regarding you in them and so on to get them to be your sex slaves.
