My understanding is that it is the same pheromone formula with a different fragrance as you mentioned. Fragrance is a powerful component however, too often scoffed at in the pheromone community. It can and will make a big difference in how and when the pheromone smells are perceived. That said, IMPI is a different ballgame altogether. There is quite a collection of pheromonal and aphrodisiac plants in that one.
