This is for a brand new manufacturer 5ml bottle of Alkemia Pheromone Alchemy P42 perfume oil. P42 is one of the only pan-sexual attractant pheromone elixirs available and is suitable for all genders and gender expressions including non-binary. From Alkemia's website: It is Alkemia's most complex pheromone compound and is designed to work in alchemy with the diversity of human pheromones to inspire desires, passions and indecent thoughts across the diversity of gender to create an inviting aura of sexual attractiveness. Pheromones are the human attraction chemicals naturally produced by our bodies. These bio-chemical messengers are subconsciously detected through our sense of smell and play a powerful role in how we respond to each other. Single pheromone blending is a complex alchemy and getting the balance right is a very delicate process. After lots of research, Alkemia created their proprietary formula using only the finest laboratory grade alpha and beta androstenols, oxytocin, and other secret ingredients. Directions: For most people, pheromone blends have no noticeable scent but they are veeerrrry concentrated. More is not better. Apply ONE swipe either alone or mixed with your favorite perfume oil or cologne to each of the pulse points behind the ears and the center of the breastbone/sternum (three swipes total). Reapply in 1-2 hours if needed, up to nine swipes. The pheromone ingredients are of the highest quality Alkemia could find. It was a lot more expensive, but they insisted only on working with reputable labs that adhere to the highest standards. These pheromone blends do not contain any animal ingredients because they are designed to attract and inspire other humans (in Alkemia's research, they discovered that some of the pheromone blends on the market today are derived from synthesized pig ingredients). In the interest of full disclosure, there are a few people for whom pheromone products don't work on for reasons not understood (either they already have enough natural pheromones, prescription medication interaction or just a slightly different chemistry).
