01Mechanism of Action

Parameter
Cardiogen
Retatrutide
Primary target
Cardiovascular cell gene expressionKhavinson 2022
GLP-1R + GIPR + Glucagon receptor (triple agonism)Jastreboff 2023
Pathway
Peptide bioregulation → modulation of SASP / inflammaging → cardiac tissue homeostasisKhavinson 2022
Triple-receptor activation → ↑insulin (GLP-1+GIP), ↓gastric emptying, ↑lipid handling, ↑energy expenditure (glucagon component)Jastreboff 2023
Downstream effect
Suppression of senescence-associated secretory phenotype (SASP), reduction of age-related inflammatory markers, modulation of heat shock protein expression in cardiac tissue
Maximal weight loss across class. Glucagon component drives lipolysis and energy expenditure beyond GLP-1+GIP aloneJastreboff 2023
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 peptide engineered for balanced affinity at three incretin / glucagon receptorsJastreboff 2023
Antibody development

05Administration Protocol

Parameter
Cardiogen
Retatrutide
1. Reconstitution
Add sterile water or saline per manufacturer instructions (typically 1–2 mL per lyophilised vial). Roll gently to dissolve.
Investigational peptide. Research vials reconstituted with bacteriostatic water per label.
2. Injection site
Subcutaneous — abdomen or thigh. Rotate sites. Use sterile technique.
SQ — abdomen, thigh, or upper arm. Rotate weekly.
3. Timing
Variable — often evening injection. No established circadian preference.
Once weekly, same day.
4. Storage
Lyophilised: refrigerate 2–8 °C, protect from light. Reconstituted: use immediately or refrigerate, discard after 7–14 days per labeling.
Refrigerate 2–8 °C. Light-protected.
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
