  • Peptide Structure
  • Tripeptide (Ala-Glu-Asp), 290 Da
  • Polypeptide complex, 3,000–5,000 Da
  • Cartalax's smaller size simplifies synthesis and quality control; Thymalin's heterogeneity complicates standardization
  • Primary Target Tissue
  • Skeletal muscle (myocytes, satellite cells)
  • Thymus gland (thymic epithelial cells, thymocytes)
  • No functional overlap. Entirely distinct organ systems
  • Mechanism of Action
  • Chromatin binding, transcription factor modulation (MyoD, myogenin upregulation)
  • Thymic epithelial receptor activation, T-cell maturation signaling (IL-2/IL-7 pathway)
  • Both involve gene expression changes, but at different cellular targets
  • Typical Dosing Range
  • 0.1–1.0 mg per dose (10–100 mcg/kg in rodents)
  • 1–10 mg per dose (varies by polypeptide fraction concentration)
  • Thymalin requires higher absolute doses due to multi-fraction composition
  • Administration Route
  • Subcutaneous or intramuscular injection
  • Intramuscular injection preferred over subcutaneous
  • Parenteral route mandatory for both; oral bioavailability negligible
  • Duration of Effect
  • Transcriptional changes persist 48–72 hours post-dose
  • Immunomodulatory effects accumulate over 7–14 day treatment courses
  • Cartalax shows per-dose efficacy; Thymalin requires cumulative dosing
  • Storage Requirements
  • Lyophilized powder at −20°C; reconstituted solution at 2–8°C, use within 14 days
  • Lyophilized powder at −20°C; reconstituted solution at 2–8°C, use within 7 days
  • Thymalin's peptide heterogeneity increases degradation risk post-reconstitution
  • Primary Research Context
  • Sarcopenia models, muscle regeneration, disuse atrophy
  • Immune senescence, thymic involution, T-cell dysfunction
  • Select based on target organ system. Not interchangeable
