01Mechanism of Action

Parameter
Cardiogen
Dermorphin
Primary target
Cardiovascular cell gene expressionKhavinson 2022
μ-opioid receptors (central and peripheral)Negri 1992Steel 2014
Pathway
Peptide bioregulation → modulation of SASP / inflammaging → cardiac tissue homeostasisKhavinson 2022
μ-receptor activation → G-protein coupling → adenylyl cyclase inhibition → neuronal hyperpolarization
Downstream effect
Suppression of senescence-associated secretory phenotype (SASP), reduction of age-related inflammatory markers, modulation of heat shock protein expression in cardiac tissue
Potent analgesia, reduced nociceptive signaling, opioid-mediated CNS and peripheral effects
Feedback intact?
Presumed — peptide bioregulators act via gene regulation, not receptor agonism
N/A — exogenous opioid agonist
Origin
Derived from cardiac tissue peptide extracts; synthetic analogue based on Khavinson bioregulator methodology
Phyllomedusa sauvagei and P. bicolor frog skin — gene-encoded with natural D-amino acid incorporationAmiche 1998Mignogna 1992
Antibody development
Site-directed antibodies produced for detection and purificationCucumel 1996

02Dosage Protocols

Parameter
Cardiogen
Dermorphin
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 studies · In vitro assays
Route
Subcutaneous injection
Duration
10–20 day courses, repeated 2–4× per year
Russian geriatric protocols; unclear extrapolation to general populations.
Legal status
Controlled substance in many jurisdictions · Research only
Not approved for human use.
Animal research (ICV)
Low nanomolar to picomolar range
Intracerebroventricular administration in rodent models.
Detection limit (doping)
5 pg/mL in equine plasma/urineSteel 2014
High-throughput LC-MS/MS screen developed for racing industry.
Duration of action
10–120 minutes (dose-dependent, intrathecal)
Human toxicity
Kambô ritual (P. bicolor skin) — violent emesis, vasodilation, fluid shifts, ADH dysregulationTran 2025

04Side Effects & Safety

Parameter
Cardiogen
Dermorphin
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
Opioid effects
Respiratory depression, sedation, euphoria, tolerance, dependence risk
CNS effects
Analgesia (high-affinity sites), catalepsy (low-affinity sites)Negri 1992
Kambô ritual toxicity
Violent emesis, vasodilation, profound fluid shifts, hyponatremia, ADH dysregulation, brain death (case report)Tran 2025
Peripheral effects
GI motility inhibition (ileum > vas deferens in vitro)Negri 1992
Receptor selectivity caveat
Two μ-receptor subtypes — differential behavioral effects (analgesia vs. catalepsy)Negri 1992
Proteolytic stability
Tyr³-Pro⁶ bond relatively unstable; endogenous enzymes may produce tetrapeptide fragmentsCucumel 1996
Absolute Contraindications
Cardiogen
  • ·Active malignancy (theoretical peptide growth factor concern)
  • ·Hypersensitivity to peptide components
Dermorphin
  • ·Human use — not approved by any regulatory authority
  • ·Controlled substance status — possession illegal in many jurisdictions
  • ·Known opioid hypersensitivity or respiratory compromise
Relative Contraindications
Cardiogen
  • ·Acute cardiac events (no safety data in acute MI, unstable angina)
  • ·Pregnancy / lactation (no reproductive toxicity data)
Dermorphin
  • ·Any context outside approved animal research protocols
  • ·CNS depressant co-administration

05Administration Protocol

Parameter
Cardiogen
Dermorphin
1. Reconstitution
Add sterile water or saline per manufacturer instructions (typically 1–2 mL per lyophilised vial). Roll gently to dissolve.
Dermorphin is a controlled substance in many jurisdictions and is not approved for human use. Possession, synthesis, or distribution may be illegal. Use is restricted to licensed research settings under institutional review.
2. Injection site
Subcutaneous — abdomen or thigh. Rotate sites. Use sterile technique.
In rodent models, intracerebroventricular (ICV) or intrathecal injection is used at nanomolar to picomolar concentrations. Subcutaneous administration also documented. All protocols require IACUC approval.
3. Timing
Variable — often evening injection. No established circadian preference.
High-throughput LC-MS/MS screens developed for anti-doping programs detect dermorphin and 17 related peptides in equine and human urine/plasma at limits as low as 5 pg/mL.Steel 2014
4. Storage
Lyophilised: refrigerate 2–8 °C, protect from light. Reconstituted: use immediately or refrigerate, discard after 7–14 days per labeling.
Application of Phyllomedusa bicolor skin secretions to superficial burns. Not recommended — associated with severe toxicity including violent emesis, hyponatremia, and documented case of brain death.Tran 2025
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.
