  • Primary Target Tissue
  • Gastric mucosa (stomach lining epithelial cells)
  • Thymus gland and peripheral T-lymphocytes
  • Non-overlapping tissue targets. Not interchangeable
  • Mechanism of Action
  • Peptide receptor signaling at gastric epithelial cells, upregulating cytoprotective gene expression and mucosal regeneration
  • Thymic hormone replacement restoring T-cell differentiation pathways disrupted by thymic involution
  • Cartalax = localized repair; Thymalin = systemic immune restoration
  • Half-Life
  • Approximately 2–4 hours (rapidly metabolized locally)
  • Approximately 6–8 hours (systemic circulation with thymic tissue accumulation)
  • Cartalax requires more frequent dosing due to shorter half-life
  • Standard Research Dosing
  • 0.1–0.5 mg per administration, daily for 10–20 days
  • 5–10 mg per administration, daily for 5–10 days
  • Thymalin uses higher absolute doses due to systemic distribution
  • Onset of Observable Effects
  • 48–72 hours (epithelial cell proliferation markers)
  • 7–10 days (T-cell count elevation)
  • Cartalax shows faster localized effects; Thymalin requires immune cell maturation time
  • Contraindications
  • None documented in standard research protocols
  • Autoimmune disorders, hyperthyroidism, acute infections
  • Thymalin carries immune-specific contraindications due to T-cell upregulation
