Yes but its a moot point really. It doesn't cross the blood brain barrier if you put it into yourself. From what I understand it can cross the other way when your brain makes it but can't come the other direction. So much like loperimide is an opiate that doesn't cross the BBB so only works on receptor sites in the g.I. tract so its great for taking care of diarrhea but not much else, oxytocin I would have to imagine would work in relatively the same way. You would not get high but it may affect you physically in some way but honestly I dont think I'd even bother.
