01Mechanism of Action

Parameter
Cardiogen
Thymalin
Primary target
Cardiovascular cell gene expressionKhavinson 2022
T-cell precursors + thymus-axis maturation pathwayKhavinson 2002
Pathway
Peptide bioregulation → modulation of SASP / inflammaging → cardiac tissue homeostasisKhavinson 2022
Modulation of T-cell differentiation + thymic hormone restoration in age-involuted thymusKhavinson 2002
Downstream effect
Suppression of senescence-associated secretory phenotype (SASP), reduction of age-related inflammatory markers, modulation of heat shock protein expression in cardiac tissue
Restored T-cell populations, improved immune surveillance, reduced infection rates in elderlyKhavinson 2002
Feedback intact?
Presumed — peptide bioregulators act via gene regulation, not receptor agonism
Origin
Derived from cardiac tissue peptide extracts; synthetic analogue based on Khavinson bioregulator methodology

05Administration Protocol

Parameter
Cardiogen
Thymalin
1. Reconstitution
Add sterile water or saline per manufacturer instructions (typically 1–2 mL per lyophilised vial). Roll gently to dissolve.
Add 1–2 mL saline or bacteriostatic water per 10 mg vial.
2. Injection site
Subcutaneous — abdomen or thigh. Rotate sites. Use sterile technique.
Intramuscular — deltoid or gluteal. Rotate sites.
3. Timing
Variable — often evening injection. No established circadian preference.
Morning preferred during cycle.
4. Storage
Lyophilised: refrigerate 2–8 °C, protect from light. Reconstituted: use immediately or refrigerate, discard after 7–14 days per labeling.
Lyophilised: refrigerate, light-protected. Reconstituted: use immediately.
5. Needle
27–30G insulin syringe, 45° angle for subcutaneous administration.
23–25G, 25–38 mm IM needle.

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
Thymalin
+ Thymosin α-1
Moderate
View Thymosin α-1

Thymalin is a polypeptide complex; Thymosin α-1 is a single purified peptide. Both target the thymus-axis but at different levels — Thymalin restores broad thymic signaling; Tα-1 provides a specific molecular activator. Anecdotally combined for elderly immune support.

Thymalin
5–10 mg IM · daily × 7 days
Thymosin α-1
1.6 mg SQ · 2× weekly during the cycle
Primary benefit
Broad thymic restoration + targeted immune activation
