I have read something else about pheromones, to the effect that many of the formulations are derived from pig pheromones, which are actually, not surprisingly, offputting. The positive effect that these pig pheromone derived formulas have, if any, must be a placebo effect. So if you're interested in seeing if synthetic pheromones have any effect on your partner, make sure you spend the money to get the good ones. ($100 rather than $29.95) For it to be a legitimate experiment, you'd have to not tell your partner that you're wearing pheromones.
