01Mechanism of Action

Parameter
Cardiogen
Thymosin α-1
Primary target
Cardiovascular cell gene expressionKhavinson 2022
Toll-like receptor 9 (TLR9) + T-cell maturation pathwayCamerini 2001
Pathway
Peptide bioregulation → modulation of SASP / inflammaging → cardiac tissue homeostasisKhavinson 2022
TLR9 activation → ↑ IFN-α + IL-2 + IFN-γ → enhanced T-cell function + dendritic cell maturationIyer 2007
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 function, improved viral clearance, anti-tumour adjuvant effectsIyer 2007
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
Synthetic 28-AA peptide identical to natural Tα-1 isolated from thymus extractCamerini 2001

05Administration Protocol

Parameter
Cardiogen
Thymosin α-1
1. Reconstitution
Add sterile water or saline per manufacturer instructions (typically 1–2 mL per lyophilised vial). Roll gently to dissolve.
Add 1 mL sterile water per 1.6 mg vial → 1.6 mg/mL.
2. Injection site
Subcutaneous — abdomen or thigh. Rotate sites. Use sterile technique.
SQ — abdomen, thigh, or upper arm. Rotate sites.
3. Timing
Variable — often evening injection. No established circadian preference.
2× weekly, e.g. Monday + Thursday.
4. Storage
Lyophilised: refrigerate 2–8 °C, protect from light. Reconstituted: use immediately or refrigerate, discard after 7–14 days per labeling.
Lyophilised: refrigerate. Reconstituted: refrigerate, use within 24 h.
5. Needle
27–30G insulin syringe, 45° angle for subcutaneous administration.
27–31G, 4–8 mm insulin syringe.

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
