There\'s a great deal of research on these pheromones - Androstenone in particular, to a lesser extent Androstenol and to an even lesser exten Androstenone. Most of the information is through scientifically conducted experiements where differences in behavior are noted between situations with and without pheromones. The conclusions are usually interpretations of authors who are trying to make sense of results.
Androstenone is believed to be a dominant or power pheromone. Androstenol is more for attraction, playfulness or silliness, and Androsterone seems to enhance the effects of the other two.
Androstenol and Androsterone do not seem to be effective without the presence of antrostenone. People play with the ratios of the three - Many products are Androstenone only, some are a mix of Androstenol/Androstenone, and one (AE) is a mix of all three.
If you have two with different ratios - you can play with them until you\'ve hot on a combo.
