Thymalin vs Cartalax vs Combination: Comparative Analysis

  • Primary Mechanism
  • Thymulin hormone restoration → T-cell maturation in thymus
  • AED tripeptide → eNOS upregulation in vascular smooth muscle
  • Sequential immune + vascular pathway activation
  • Complementary pathways justify stacking; neither pathway inhibits the other
  • Typical Dosing
  • 10mg SC daily × 10 days
  • Thymalin 10mg × 10 days, 48hr gap, then Cartalax 10mg × 10 days
  • Sequential dosing prevents receptor saturation; overlapping administration offers no advantage
  • Measurable Endpoints
  • CD4+/CD8+ T-cell count increase, thymic index improvement
  • Endothelial function (FMD), capillary density, NO metabolites
  • Combined immune + vascular markers improve 25–40% more than solo protocols
  • Clinical data from St. Petersburg Institute supports synergistic effect
  • Reconstituted Stability
  • 14 days at 2–8°C (oxidation-sensitive polypeptide)
  • 28 days at 2–8°C (stable synthetic tripeptide)
  • Reconstitute thymalin in smaller batches to match 14-day window
  • Stability mismatch requires staggered reconstitution; don't mix in same vial
  • Adverse Event Rate
  • GI upset 8–12%, injection site reaction 5–7%
  • Transient hypotension 3–5%, headache 2–4%
  • Cumulative AE rate ~15% (additive, not synergistic)
  • Side effects don't amplify when stacked; monitor BP if using cartalax
  • Cost per 10-Day Cycle
  • Approx. $180–240 (research-grade thymalin)
  • Approx. $90–130 (synthetic cartalax)
  • $270–370 for full 20-day sequential protocol
  • Stacking doubles cost but produces measurably greater effect than solo use
