01Mechanism of Action

Parameter

Ovagen

Oxytocin

Primary target

Ovarian tissue chromatin complexes

Oxytocin receptors (OXTR) — hypothalamus, amygdala, hippocampus, ventral tegmental area

Pathway

Tissue-specific peptide → Nuclear chromatin binding → Gene expression modulation → Cellular differentiation

OXTR activation → Gq/11-coupled signaling → modulation of GABAergic, dopaminergic, serotonergic pathways → enhanced synaptic plasticity, neurogenesis, emotional regulation

Downstream effect

Proposed ovarian functional support, fertility regulation, hormonal homeostasis restoration

Social bonding enhancement, trust behavior, gaze modulation, reciprocal eye contact, anti-inflammatory and antioxidant neuroprotection, reduced amygdala threat responsePaul 2026 Prinsen 2026 Yuan 2026

Feedback intact?

Presumed physiological — Khavinson peptides described as regulatory, not replacement

Yes — endogenous oxytocin-mediated feedback via central and peripheral OXTR pathways

Origin

Extracted from bovine/porcine ovarian tissue; short synthetic peptides (2–4 amino acids)

Endogenous 9-amino-acid peptide synthesized in hypothalamic paraventricular and supraoptic nuclei, released from posterior pituitaryPaul 2026

02Dosage Protocols

Parameter

Ovagen

Oxytocin

Standard dose

10–20 mg / day (oral) or 1–2 mg SQ

Extrapolated from Khavinson-school protocols; no ovagen-specific PubMed dose studies.

—

Frequency

Once daily or cyclical (10–20 days per month)

Cyclical protocols common in Khavinson bioregulator tradition.

—

Evidence basis

Theoretical / Russian-tradition

—

Duration

4–12 weeks per cycle

Khavinson protocols typically 1–3 months; repeat cycles as needed.

—

Route

Oral (capsule) or subcutaneous

Oral absorption assumed for short peptides; SQ route mirrors other Khavinson bioregulators.

05Administration Protocol

Parameter

Ovagen

Oxytocin

1. Oral route

Typical dose: 10–20 mg once daily. Capsule form — taken on empty stomach, 20–30 min before meals. Khavinson tradition suggests morning administration.

Administer 24–48 IU (typically 3–6 puffs per nostril) using nasal spray device. Patient should be seated, head tilted slightly forward. Avoid sniffing deeply; allow passive absorption.

2. Subcutaneous route

1–2 mg per injection. Reconstitute lyophilised powder with sterile water if required. Inject into abdomen or thigh; rotate sites.

Administer 30–90 minutes before anticipated social interaction or cognitive assessment. Acute effects peak within 30–60 minutes.

3. Cyclical protocol

Common pattern: 10–20 days on, 10 days off. Aligns with menstrual cycle phases in some protocols. Repeat cycles for 2–3 months, then assess.

Dilute oxytocin 10 units in 1000 mL isotonic saline. Initiate at 0.5–2 mU/min via infusion pump. Titrate every 30–60 minutes based on contraction pattern and fetal heart rate. Continuous electronic fetal monitoring required.

4. Storage

Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within 7–14 days.

Store at 2–8 °C (refrigerated). Do not freeze. Protect from light. Discard if solution is discolored or contains precipitate.

5. Chronic dosing (research)

—

Chronic administration protocols (4–12 weeks) documented in pediatric ASD populations. Daily or twice-daily intranasal administration. Safety profile in chronic use still under investigation.
