I suggest you read this thread I wrote way back when:
It’s about setting appropriate expectations for how pheromones work and how to notice their effects. I wrote it after experimenting with pheromones for over a year as the post I wish I’d read at the start to guide me not on what to use or how to use it (there were already great posts on that) but rather on how to be the best experimenter/observer I could be of these pheromone tests.
