  • Thymalin
  • Thymic immune modulation
  • Treg upregulation reduces anti-TPO antibodies in Hashimoto's
  • Phase 2 trials (Eastern Europe)
  • 10–30 mg IM every other day for 10 doses
  • Effective for early-stage autoimmune thyroiditis; requires reconstitution within 72 hours; no effect on established hypothyroidism
  • KPV
  • NF-κB inhibition
  • Reduces IL-6 and TNF-α cytokines perpetuating thyroid inflammation
  • Preclinical and Phase 1
  • 500 mcg–2 mg subcutaneous daily
  • Anti-inflammatory support only; does not restore thyroid hormone synthesis; oral bioavailability poor without encapsulation
  • Cerebrolysin
  • Hypothalamic neuroprotection
  • Increases TRH expression in stress-induced central hypothyroidism
  • Preclinical (animal models)
  • 5–10 mL IV 5 days/week for 4 weeks
  • Targets upstream HPT axis dysfunction; irrelevant for primary thyroid failure; requires physician administration
  • Iodine peptides (marketed supplements)
  • Claimed 'thyroid nourishment'
  • None. Iodine is a substrate, not a peptide; conflated terminology
  • No valid trials
  • N/A
  • Marketing fiction; iodine is not a peptide and does not modulate immune or neuroendocrine pathways
