Oxytocin dose guide

A peptide dosage chart, one peptide at a time: its dose range, how often it’s taken, a typical run and the units on your syringe. All 69 peptides in the PepVault library.

A community reference, not medical advice. Each range is what has been studied or is commonly run, never a dose for you.

Oxytocin dosage

Best known as the "bonding hormone," oxytocin is a hypothalamic neuropeptide with broader effects than most people realize. As a nasal spray, single doses have cut how much people eat at a meal and blunted stress responses in small studies, though an 8-week trial didn't produce weight loss; anti-inflammatory effects come mostly from animal work. Commonly reported: a subtle calm, warm or more connected feeling shortly after a spray, and for many, little or inconsistent effect from dose to dose. FDA-approved only as an obstetric injection (Pitocin).

Dose range
10–40 IU (research range). Studied in research — not a recommendation.
How often
1–2× daily: 1–2x daily or as needed
A typical run
As-needed use most common. Animal studies suggest tolerance with frequent daily use, so many users cycle or use it situationally.
How it’s taken
Nasal spray: Intranasal
Evidence
Moderate: Animal studies + some human data
Half-life
~1–6 min (in blood; nasal doses peak in blood at ~15 min)

Oxytocin on your syringe

Used as a nasal spray, so it’s dosed by sprays, not drawn into a syringe.
