  • Thymosin Alpha-1
  • Thymic hormone analog. Promotes T-cell maturation and differentiation in thymus
  • Adaptive immunity (T-cell populations)
  • 2–3 times per week subcutaneously
  • 28 days in bacteriostatic water
  • Chronic viral infections, immunosenescence, post-chemotherapy immune recovery
  • Thymalin
  • Thymic extract. Contains multiple thymic peptides that enhance CD4+/CD8+ T-cell function
  • Adaptive immunity (T-cell activation and memory)
  • Age-related immune decline, autoimmune modulation, recurrent infections
