I watched this show last night - it was pretty interesting.
In one segment, "Scientists wanted to test whether copulins, a natural secretion that women emit to attract men, really affected a man's level of attraction to a woman. So they asked men to rate a group of women in photographs on attractiveness. But when the men were unknowingly given artificial copulins and asked to rate the women, they were unable to distinguish which women were attractive."
The show said that this was partially because the copulins provided an instant boost in testosterone in males.
I'm wondering if it would be possibly advantageous to inhale some artificial copulins pre-workout (or during a workout).
On a side note...it sounds like if you brought a bottle of this stuff to a club and sniffed it, you could have a real-life "Shallow Hal" effect!
