## FAQ

### Is oxytocin FDA-approved?

Yes, for specific obstetric uses—inducing or strengthening uterine contractions and controlling postpartum hemorrhage. Intranasal and behavioral-research applications are investigational and not FDA-approved.

### Is oxytocin on the WADA prohibited list?

Oxytocin is not specifically named on the WADA Prohibited List among banned peptide hormones or metabolic modulators. Athletes should confirm current status directly with WADA, as catch-all clauses may apply case by case.

### How is lyophilized oxytocin reconstituted for laboratory use?

The freeze-dried powder is dissolved in a suitable diluent such as bacteriostatic water. Final concentration equals the total peptide content of the vial divided by the volume of diluent added.
