^ Lame. I saw this documentary some time ago, about relationship related stuff. One part was about Oxytocin and they actually testet an oxytocin enriched nasal spray on a few partners, with one of them receiving a placebo spray. Most, if not all, of the people were able to figure out which one of them had been given the real thing, based on both of their actions.
It was a national mainstream channel though, so im not really surprised if you're right, which would render any testing like that utterly useless (they actually sell these sprays online, kind of a scam then). Do you know why it doesn't work? Does it not cross the bbb, poor bioavailability, too fast metabolism or what's up?
