01Mechanism of Action

Parameter
Cardiogen
TB-500
Primary target
Cardiovascular cell gene expressionKhavinson 2022
G-actin (sequestering) + cell-surface integrinsGoldstein 2012
Pathway
Peptide bioregulation → modulation of SASP / inflammaging → cardiac tissue homeostasisKhavinson 2022
Actin remodelling → cell migration; integrin-linked signaling → angiogenesis; anti-inflammatory cytokine modulationGoldstein 2012Malinda 1999
Downstream effect
Suppression of senescence-associated secretory phenotype (SASP), reduction of age-related inflammatory markers, modulation of heat shock protein expression in cardiac tissue
Accelerated wound healing, endothelial migration, hair follicle regeneration, cardiac repair (preclinical)Goldstein 2012
Feedback intact?
Presumed — peptide bioregulators act via gene regulation, not receptor agonism
Endogenous protein at baseline; supplementation amplifies
Origin
Derived from cardiac tissue peptide extracts; synthetic analogue based on Khavinson bioregulator methodology
17-AA active fragment of endogenous 43-AA thymosin β4 (TMSB4X gene)Goldstein 2012
Antibody development

02Dosage Protocols

Parameter
Cardiogen
TB-500
Standard dose
Variable — typically 10–20 mg per course
No standardised human protocol; animal-derived dosing.
2 mg per injectionGoldstein 2012
Anecdotal community range; clinical Phase 2 trials used 70–840 mcg/kg IV.
Frequency
Intermittent courses — 10–20 days, repeated periodically
Khavinson-school bioregulators typically dosed as periodic interventions, not continuous.
2× per week (loading); then 1× per week (maintenance)
Evidence basis
Animal models / mechanistic studies
No Phase 1+ human trials in PubMed.
Animal-strong + Phase 2 dermal/ocular trialsGoldstein 2012
Route
Subcutaneous injection
Duration
10–20 day courses, repeated 2–4× per year
Russian geriatric protocols; unclear extrapolation to general populations.
4–8 weeks loading; longer maintenance for chronic injury
Lower / starter dose
1 mg per injection
Reconstitution
Bacteriostatic water, 1–2 mL per 5 mg vial
Timing
Evening or pre-rest preferred (anecdotal)
Half-life
~2 hours (estimated; tissue uptake longer)

05Administration Protocol

Parameter
Cardiogen
TB-500
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 bacteriostatic water to 5 mg vial → 2.5–5 mg/mL. Roll gently.
2. Injection site
Subcutaneous — abdomen or thigh. Rotate sites. Use sterile technique.
SQ near injury site (preferred), or systemic SQ (abdomen). Rotate sites.
3. Timing
Variable — often evening injection. No established circadian preference.
Evening or pre-sleep is most common anecdotal timing.
4. Storage
Lyophilised: refrigerate 2–8 °C, protect from light. Reconstituted: use immediately or refrigerate, discard after 7–14 days per labeling.
Lyophilised: room temp, light-protected. Reconstituted: refrigerate, ≤30 days.
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
TB-500
+ BPC-157
Strong
View BPC-157

TB-500 and BPC-157 cover complementary halves of tissue repair: BPC-157 upregulates VEGFR2-driven angiogenesis and fibroblast outgrowth; TB-500 sequesters G-actin to enable endothelial / epithelial migration. The anecdotal canonical "healing stack" — pairs especially well for tendon and ligament injuries.

TB-500
2 mg SQ · 2× per week
BPC-157
250–500 mcg SQ · daily
Primary benefit
Combined angiogenesis + cell migration for tendon/ligament/muscle repair
