Oxytocin

Pitocin

An FDA-approved hormone for labor whose off-label "bonding and mood" use rests on a much weaker and inconsistent evidence base.

Verdict, B · Viable

The approved obstetric use is rock-solid, but that is not what buyers are after, the off-label bonding/mood evidence is mixed and poorly reproduced. A B on the strength of approval pedigree and a benign low-dose safety profile, with a clear caveat that the popular use case is the weakly-supported one.

How we compute this →

Overview

Oxytocin is an endogenous nonapeptide, FDA-approved as Pitocin for labor induction and postpartum use, with an extensive clinical record in that obstetric setting. Its popular off-label use is entirely different: low-dose intranasal oxytocin for social bonding, anxiety and mood, where the human literature is large but notably inconsistent and has struggled to replicate. The approved injectable and the off-label intranasal forms should not be conflated; the buyer-relevant product is the less-validated intranasal one.
