  • 25–40 years
  • 1–2mg subcutaneous
  • 6–8 weeks
  • 2–4 weeks
  • Acute tissue repair, wound healing acceleration, collagen maintenance
  • Baseline GHK-Cu levels still adequate; lower doses effective due to higher receptor sensitivity and normal copper transport
  • 50–65 years
  • 1.5–3mg subcutaneous
  • 8–12 weeks
  • 4–6 weeks
  • Collagen density restoration, chronic inflammation modulation, age-related fibroblast activation
  • Requires higher doses to overcome reduced ceruloplasmin, hormone-driven collagen suppression, and inflammaging
  • 65+ years
  • 2–3.5mg subcutaneous
  • 10–14 weeks
  • Sarcopenia mitigation, osteoarthritis symptom reduction, chronic wound management
  • Maximum tolerated dose often needed; longer cycles with extended washouts due to slower peptide clearance rates
