Dumb question on iu

[Moparman]

So I bough some injectable oxytocin. The vial says 1200 iu on it. I haven't received it yet.

Does that mean 1200 iu per ml?

If I want 20 iu what mark on the insulin pin do I go to?

Does 20 iu sound right ?

Where do you get that? And what are you hoping to get from it? Im curious because I havent felt the things oxytocin promotes in months.
