Oxytocin Dosage Protocols: All Vial Sizes
DSIP is a 9-amino-acid neuropeptide first isolated from rabbit cerebral venous blood during electrically induced sleep. It modulates delta-wave sleep and exhibits anti-stress effects. Choose your vial size below; each size has its own exact dosing table.
Choose Your Vial Size
| Vial | Final volume | Concentration | One U-100 unit | |
|---|---|---|---|---|
| 5 mg | 3 mL | 1.67 mg/mL | 16.67 mcg in 0.01 mL | Open protocol → |
| 10 mg | 3 mL | 3.33 mg/mL | 33.33 mcg in 0.01 mL | Open protocol → |
Doses are the same research amounts across sizes; the vial size changes the concentration, so syringe units differ. Always use the table for your exact vial.
Storage Instructions
| State | Temperature | Duration |
|---|---|---|
| Lyophilized | −20°C (−4°F) | Up to 24 months, dry & dark |
| Reconstituted | 2–8°C (35–46°F) | Up to 28 days, protect from light |
Important Notes
How This Works
Oxytocin is synthesized in the supraoptic and paraventricular nuclei of the hypothalamus. It acts peripherally (stimulating uterine contraction and milk ejection) and centrally via limbic and prefrontal projections. Central effects include social bonding, trust enhancement, anxiolysis, and pair-bonding — mediated by high oxytocin receptor density in the amygdala, nucleus accumbens, and prefrontal cortex.
Potential Benefits & Side Effects
Potential Benefits
- Studied for social-cognition and trust enhancement.
- Anxiolytic effects in social-anxiety models.
- Established clinical use in obstetrics (parturition and lactation).
- Pair-bonding and empathy effects in research models.
Side Effect Profile
- Generally well-tolerated.
- Mild injection-site discomfort.
- Nasal irritation (intranasal route).
- Mood lability in some subjects. Caution during pregnancy — affects uterine tone.
Lifestyle Factors
- Subcutaneous or intranasal — intranasal preferred for CNS social-bonding effects.
- Timing matters — dose 15–30 min before target social or therapeutic context.
- Effects last 1–2 hrs; half-life is ~3 min, CNS effects persist longer.
- Rotate subcutaneous injection sites with daily use.
Injection Technique
- Subcutaneous or intranasal. Rotate sub-Q injection sites.
- Once daily or PRN timing is universal — DSIP is short-acting.
