OxyCalm is the best spray delivery of Oxytocin out there, bar none. I know for a fact that the Oxytocin used in OxyCalm comes from one of only 2 factories in the world that have approvals for Oxytocin use in both animals and humans. Of course, OxyCalm is not FDA approved, but the Oxytocin used in the preparation of OxyCalm is as pure as it gets.
Good stuff!
