Also called Pitocin, Syntocinon

InjectableEvidence AEvery day
Half-life

Typical vial

Research amounts

per administration

Common schedule
Every day
Tested in people

A human trial worked out how much to take and how often, so a dosing schedule is shown.

Licensed as a medicine in the US and EU.

The human evidence for Oxytocin used the intravenous route. The draw worked out here assumes a subcutaneous injection, so the amount is not a direct read-across.

Vial label

Copy this into your label printer.

Published research contexts for Oxytocin describe 2040 mcg per administration. Descriptive only, not a recommendation.

Only a few minutes in plasma, so any curve here is a brief spike.

A nonapeptide hormone, licensed as a medicine and given by intravenous infusion, intramuscularly, or intranasally in research; amounts are usually stated in international units. No subcutaneous schedule is established, so no schedule table is shown.

Modelled level — every day

1× is the peak after a single dose.

Steady-state peak
0.97× single dose

Read off the modelled curve, not an even-interval formula
