The amounts here are tiny, but the volumes are different than what we use with synthetic pheromones. 2 nmol/microliter [thanks truth!] of androstenone (5alpha-androst-16-en-3-one) is about 0.0014%. To compare, PI has 0.05% -none and APC has 0.005%

Of course, we only use a drop or two of PI (about 100 microliters), while we sweat more profusely. The same amount of -none as 100 microliters of PI would be in about 3.5 ml of sweat. That\'s a lot of sweat for me, unless I\'m exercising.

I don\'t know much about the other compounds mentioned in the study, but they are probably metabolites of -none. From what I\'ve read here, they\'re not in any of the pheromone products.

This study may not have much to do with sexual arousal. Notice that the sweat they measured was produced with adrenaline. That means that it was \"fear\" sweat, which is usually stinky stuff. Personally, I smell different when I\'m afraid vs. exercising vs. aroused.

So, I don\'t really see how to translate this study to \'mones from bottles.

Hope this helps,
