About Oxytocin
Oxytocin is a nine-amino-acid hormone made in the hypothalamus and released by the posterior pituitary. It controls uterine contraction and milk release, and acts in the brain on social behavior.
Synthetic oxytocin is an approved obstetric drug.
How Oxytocin works
Oxytocin acts on the oxytocin receptor, a G-protein coupled receptor found in the uterus, breast tissue and many brain regions.
In the body it triggers contractions and milk letdown. In the brain it’s involved in social recognition, bonding and stress responses, which is what most current research is about.

Reconstituting Oxytocin 5mg
Concentration is just the amount in the vial divided by the water you add. With 5mg in this vial:
- 1ml of bacteriostatic water gives 5mg/ml
- 2ml of bacteriostatic water gives 2.5mg/ml
- 3ml of bacteriostatic water gives 1.67mg/ml
Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label.
Use sterile bacteriostatic water. Warm the sealed vial to room temperature first so no condensation gets in, add the water slowly along the glass wall, and swirl gently until it’s clear. Never shake.
How to store Oxytocin 5mg
Unopened, keep Oxytocin 5mg in a fridge at 2 to 8°C, or in a freezer at -20°C if it’ll be a while before you use it. Keep it out of direct light. Once mixed, keep it refrigerated and use it within about 28 days, which is how long bacteriostatic water stays good after opening.
