Phiero Xtreme features three powerful pheromones at a 20% concentration: Androstenone, Delta 16-OL, and A-Keto. Most pheromone perfumes offer a concentration between 1% and 5%, making Phiero Xtreme significantly superior. Combined, its pheromones act on other people's primal instincts, as they are naturally detected through the sense of smell with the vomeronasal organ, producing a feeling of comfort and a loss of shyness so that relationships can emerge more easily, thus favoring conquest and male attractiveness. In addition, this pheromone concentrate does not contain any added aroma, so it can be applied directly to the skin and then sprayed with perfume; or it can be mixed into a man's usual perfume or cologne bottle before applying it, making him feel even more confident, helping to enhance sexual attraction when initiating an approach. Phiero Xtreme pheromone perfume acts within a maximum of 30 minutes of application and its effect lasts between 6 and 8 hours on the skin, and up to two weeks on clothing.
