Gentlemen, This is the “new and improved” version of Chikara. Chikara is quite literally the state of the art in the field of pheromones. It contains an all-new proprietary formula of the 3 pheromones found in most of the top-selling pheromone products, PLUS 4 new pheromones never before used in perfumery. That is a total of 7 pheromones including the standard androsteNONE, androsteNOL and androsteRONE. Overall, the total guaranteed pheromone content per bottle is a whopping 10 mg! That is exactly double the amount of pheromones found in the leading Primal Instinct, and at the same price. And the fragrance is fantastic! It is a natural for pheromones, and more specifically for what Chikara does. Chikara doesn’t just represent the next step in pheromone technology, it takes it to a whole new level. Try it and you will see what I mean. Experience the mysterious power of the orient. Experience Chikara.
