All the old jokes regarding being able to "bottle" sex appeal turn out to hold a basis in reality. In the recent past scientists discovered how to separate and concentrate the chemical-hormonal components -- called pheromones -- that create sexual attraction in humans. It's now possible to put on pheromones and expose their indiscernible sexy signals at will.

The effect of pheromones has been very well researched. They produce a spontaneous, almost automatic sexual response, which scientists brand a "releaser" effect. Every person possesses a special "odor print" that is just as unique as fingerprints, created by compounds released from the sebaceous glands, sweat glands and other glands. Among the substances and compounds released are pheromones, which drift into our partner's nasal passage and arouse specific receptors. Researchers are still examining the receptors to determine whether the "vomeronasal organ" is devoted only to sensing pheromones, or whether pheromone receptors are a piece of a more complicated system together with with olfactory receptors in the nasal passage.

The two compounds that are most widely known as pheromones are androstadienone (AND) and estratetraenol (EST). AND is a derivative of testosterone and EST is a relative of estrogen. Researchers have proven that the substances alter brain patterns as discerned by EEGs, functional MRIs, and PET scans, and induce mood swings. That evidence matches what pheromones would do.

Non-natural versions of these compounds can be even more powerful and effectual than one's natural "odor print" particularly because Americans do so many things to eliminate any hint of natural smell and perspiration. In the present society, our bathing, deodorizing, cologne-applying and almost sterile approach to hygiene keep our natural pheromones from carrying out their function.

That is why the concept of concentrated pheromones is so sensible. The trick is looking for a good source of pure pheromones, not merely diluted or even fake preparations that are making claims. There are a few satisfactory products out there that actually are what they say and have an excellent reputation for giving rise to more stimulation, more interest, more attraction and greater desire in the opposite sex.
