  • Thymalin
  • Thymic restoration, T-cell maturation
  • Immune senescence, SASP reduction
  • Phase II: 34% increase CD4+ T-cells, 22% reduction SASP markers (12 weeks, Immunity & Ageing 2021)
  • 10mg subcutaneous, twice weekly
  • Most overlooked driver of premature aging. Immune dysfunction precedes visible tissue damage by years
  • Epithalon
  • Telomerase activation, chromosomal repair
  • Telomere shortening, replicative senescence
  • 33% increase mean telomere length, 42% extension of Hayflick limit (St. Petersburg Institute of Bioregulation)
  • 10mg subcutaneous, 10-day cycles every 6 months
  • Only peptide with direct evidence of reversing cellular aging clock. Mechanistically distinct from all cosmetic interventions
  • GHK-Cu
  • Collagen synthesis, senescent cell clearance
  • Dermal matrix degradation, fibroblast senescence
  • 18% increase dermal thickness, 32% reduction MMP-1 (Journal of Cosmetic Dermatology 2022)
  • 3mM topical or 2mg subcutaneous daily
  • Dual action. Stimulates collagen production while clearing cells that degrade it; rare combination in one molecule
