01Mechanism of Action

Parameter
Cardiogen
PTD-DBM
Primary target
Cardiovascular cell gene expressionKhavinson 2022
CXXC5–Dishevelled protein-protein interaction
Pathway
Peptide bioregulation → modulation of SASP / inflammaging → cardiac tissue homeostasisKhavinson 2022
Inhibit CXXC5 binding to Dishevelled → Release Wnt/β-catenin pathway inhibitionLee 2015Ryu 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
Activated Wnt/β-catenin signaling promotes hair follicle regeneration, dermal stem cell activation, reduced myofibroblast differentiation
Feedback intact?
Presumed — peptide bioregulators act via gene regulation, not receptor agonism
Not applicable — pathway derepression rather than receptor agonism
Origin
Derived from cardiac tissue peptide extracts; synthetic analogue based on Khavinson bioregulator methodology
Engineered fusion: cell-penetrating PTD sequence + Dvl-binding motif targeting CXXC5
Antibody development

02Dosage Protocols

Parameter
Cardiogen
PTD-DBM
Standard dose
Variable — typically 10–20 mg per course
No standardised human protocol; animal-derived dosing.
Frequency
Intermittent courses — 10–20 days, repeated periodically
Khavinson-school bioregulators typically dosed as periodic interventions, not continuous.
Evidence basis
Animal models / mechanistic studies
No Phase 1+ human trials in PubMed.
Animal models only (mice)
Route
Subcutaneous injection
Duration
10–20 day courses, repeated 2–4× per year
Russian geriatric protocols; unclear extrapolation to general populations.
Wound healing protocol
Hydrogel patch delivery (concentration not disclosed)
Pyrogallol-HA patch, murine model.
Hair regeneration protocol
Topical application (exact dose not disclosed)
Wound-induced hair neogenesis model, mice.
Co-administration
Valproic acid (GSK-3β inhibitor) for wound healing synergyLee 2023
Combined treatment maximized scar reduction.
Human translation
No published human studies

04Side Effects & Safety

Parameter
Cardiogen
PTD-DBM
Injection site reactions
Mild erythema, induration (presumed)
Systemic adverse events
No documented serious AEs in available literature
Very limited safety data; no rigorous pharmacovigilance.
Immunogenicity
Unknown — no antibody development studies published
Long-term safety
Unknown — no extended human trials indexed in PubMed
Unknown — no chronic dosing or human data
Reported adverse events
None reported in animal studies
Wnt pathway activation risks
Theoretical risk of aberrant proliferation; Wnt dysregulation linked to tumorigenesis
Delivery vehicle effects
HA-PG hydrogel well-tolerated in mice; human translation pending
Absolute Contraindications
Cardiogen
  • ·Active malignancy (theoretical peptide growth factor concern)
  • ·Hypersensitivity to peptide components
PTD-DBM
  • ·Active malignancy (Wnt pathway involvement in tumorigenesis)
  • ·Pregnancy / lactation (no safety data)
Relative Contraindications
Cardiogen
  • ·Acute cardiac events (no safety data in acute MI, unstable angina)
  • ·Pregnancy / lactation (no reproductive toxicity data)
PTD-DBM
  • ·History of Wnt-driven tumors
  • ·Skin lesions with uncertain malignant potential

05Administration Protocol

Parameter
Cardiogen
PTD-DBM
1. Reconstitution
Add sterile water or saline per manufacturer instructions (typically 1–2 mL per lyophilised vial). Roll gently to dissolve.
Pyrogallol-functionalized hyaluronic acid (HA-PG) hydrogel patch loaded with PTD-DBM peptide, applied directly to wound bed. Adhesive hydrogel provides sustained release over multiple days.Lee 2023
2. Injection site
Subcutaneous — abdomen or thigh. Rotate sites. Use sterile technique.
Topical application to scalp or wound site. Precise formulation not disclosed; studies used Cxxc5 knockout or direct peptide application in wound-induced hair neogenesis models.Ryu 2023
3. Timing
Variable — often evening injection. No established circadian preference.
PTD-DBM + valproic acid (GSK-3β inhibitor) in HA-PG patch showed synergistic effect on scar reduction and regenerative wound healing. VPA enhances Wnt pathway activation downstream.Lee 2023
4. Storage
Lyophilised: refrigerate 2–8 °C, protect from light. Reconstituted: use immediately or refrigerate, discard after 7–14 days per labeling.
Not disclosed in available literature. Peptide stability and storage conditions not published.
5. Needle
27–30G insulin syringe, 45° angle for subcutaneous administration.

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
