01Mechanism of Action

Parameter

Cardiogen

Oxytocin

Primary target

Cardiovascular cell gene expressionKhavinson 2022

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

Pathway

Peptide bioregulation → modulation of SASP / inflammaging → cardiac tissue homeostasisKhavinson 2022

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

Downstream effect

Suppression of senescence-associated secretory phenotype (SASP), reduction of age-related inflammatory markers, modulation of heat shock protein expression in cardiac tissue

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 — peptide bioregulators act via gene regulation, not receptor agonism

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

Origin

Derived from cardiac tissue peptide extracts; synthetic analogue based on Khavinson bioregulator methodology

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

·Prior uterine surgery or cesarean section (relative — use cautiously)

05Administration Protocol

Parameter

Cardiogen

Oxytocin

1. Reconstitution

Add sterile water or saline per manufacturer instructions (typically 1–2 mL per lyophilised vial). Roll gently to dissolve.

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. Injection site

Subcutaneous — abdomen or thigh. Rotate sites. Use sterile technique.

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

3. Timing

Variable — often evening injection. No established circadian preference.

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: refrigerate 2–8 °C, protect from light. Reconstituted: use immediately or refrigerate, discard after 7–14 days per labeling.

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

5. Needle

27–30G insulin syringe, 45° angle for subcutaneous administration.

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.

06Stack Synergy

Cardiogen

+ Thymalin

Moderate

View Thymalin →

Khavinson-school multi-organ bioregulator approach: thymalin (thymic peptide) addresses immune senescence while cardiogen targets cardiac tissue. Combined use in geriatric populations demonstrated normalisation of cardiovascular, endocrine, and immune parameters with reduced mortality over 6–8 years of observation.

Cardiogen: 10–20 mg SQ · 10–20 day course
Thymalin: 10–30 mg IM · concurrent or sequential courses
Frequency: 2–4 courses per year
Primary benefit: Multi-system aging mitigation, cardiovascular and immune homeostasis
