Don’t know about this one. It certainly smells human, but it’s structure didn’t come from a sweat analysis. Smells like armpits and groin area stuff to me.
If it proves itself as a useful pheromone, we can send it and a few sweat samples along to an analytical lab to find out where it comes from for sure. You might want to get a head start, and start ringing out your sock sweat into a little vial now.
