Oxytocin Dosing & Reconstitution Calculator
Neuropeptide hormone promoting bonding, stress relief, and social cognition.
TL;DR - Oxytocin is a sexual health peptide with a typical starting dose of 10 µg. For a 5 mg vial, add 1 mL bacteriostatic water to yield 5000 µg/mL.

Frequently Asked
How do I reconstitute Oxytocin?
Add 1 mL of bacteriostatic water to a 5 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 5000 µg/mL.
What is the recommended dose of Oxytocin?
A typical research dose is 10 µg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a Oxytocin vial?
A 5 mg vial reconstituted with 1 mL BAC water yields approximately 500 doses at 10 µg each.
How many IU is 10 µg of Oxytocin on a syringe?
With a 5 mg vial reconstituted in 1 mL bacteriostatic water, the concentration is 5000 µg/mL. For a 10 µg dose: Volume = 10 µg ÷ 5000 µg/mL = 0.002 mL. Draw to the 0.2 line on a 100-unit insulin syringe. You can adjust these values in the ASCEND calculator for any vial size.
What does a Oxytocin dosage calculator do?
A Oxytocin dosage calculator converts your vial size and BAC water volume into an exact syringe draw in IU. Enter your vial strength (5 mg), reconstitution volume (1 mL), and target dose to get the precise line to draw on an insulin syringe.
What is the Oxytocin reconstitution calculator formula?
Draw volume (mL) = Dose (µg) divided by Concentration (µg/mL). For a 5 mg vial with 1 mL BAC water: concentration = 5000 µg/mL. For a 10 µg dose, the ASCEND calculator gives the exact IU line on your syringe instantly.
Peptide Intelligence
What is the half-life of Oxytocin?
Intranasal Oxytocin has a plasma half-life of approximately 3 minutes for the peripheral fraction. Central effects are believed to persist longer via direct nose-to-brain delivery through olfactory/trigeminal pathways, bypassing the blood-brain barrier. Research often uses intranasal routes for behavioral studies.
What receptors does Oxytocin act on beyond social bonding?
Oxytocin acts on OXTR receptors expressed in the brain, uterus, mammary glands, heart, and immune cells. Beyond bonding, it modulates pain perception, anxiety, HPA axis stress responses, cardiovascular function, and gut motility.
What behavioral and psychiatric effects is Oxytocin researched for?
Active research areas include social anxiety disorder, autism spectrum disorder, PTSD, postpartum depression, and addiction. Meta-analyses show modest but consistent pro-social and anxiolytic effects. Nasal Oxytocin research has produced mixed results, partly due to delivery reliability challenges.
