How many units of Oxytocin should I draw?

It depends on your vial size, BAC water, and dose. For a 1IU vial with 2mL BAC water, a beginner dose of 12IU is typically 2 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to Oxytocin?

The standard amount is 2mL of bacteriostatic water for a 1IU vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a Oxytocin vial last?

At a beginner dose of 12IU daily, a 1IU vial lasts about 83 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for Oxytocin?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

Very small draw (2.4 units) — difficult to measure accurately. Consider using less BAC water for a more concentrated solution.

Try 1mL BAC water for an easier-to-measure draw.

Summary: Add 2mL BAC water to your 1mg vial. Draw to 2.4 units on a U-100 syringe for a 12mcg dose. This vial will last 83 doses.

Oxytocin Pharmacokinetics

Pharmacokinetics — Active Dose Over Time

t½ = ~3 min (IV), central effects last 2-4 hours (intranasal)

After 1 half-life (3h): 50% remainsAfter 2 half-lives (6h): 25% remainsAfter 3 half-lives (9h): 12.5% remains

At a 24mcg dose: 50% = 12mcg remaining after 3h. Recommended frequency: Daily.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

Oxytocin Dosing Protocol

Level	Dose / Injection	Frequency
Beginner	12 IU	Daily
Moderate	24 IU	Daily
Aggressive	48 IU	Daily

Note: Dosing in IU: 1 IU ≈ 1.68 mcg. Beginner = ~12 IU, moderate = ~24 IU, aggressive = ~48 IU. Intranasal preferred for behavioral effects. FDA-approved as Pitocin (IV) for labor only — all psychiatric and social applications are off-label. Cycle: 4 weeks on, 4 weeks off.

About Oxytocin

Oxytocin is a nine-amino-acid neuropeptide produced in the hypothalamus and released by the posterior pituitary. It's best known for its role in labor and breastfeeding, but research over the past two decades has revealed a much broader profile. Intranasal oxytocin has been studied extensively for social bonding, anxiety reduction, trust behavior, and sexual health — earning it the nickname "the love hormone." The FDA approved synthetic oxytocin (Pitocin) decades ago for labor induction and postpartum hemorrhage control. All behavioral and psychiatric applications — social anxiety, autism spectrum support, PTSD, sexual dysfunction — remain investigational. A 2005 study by Kosfeld et al. in Nature showed intranasal oxytocin significantly increased trust in a financial game, sparking a wave of behavioral research. Plasma half-life is extremely short at roughly 3 minutes IV, but central effects after intranasal dosing persist for 2-4 hours. Bioavailability is low (under 2% systemically), yet brain concentrations reach meaningful levels through nasal administration. Doses in clinical trials typically range from 20-40 IU with no serious adverse effects in short-term studies.
