  • The following table compares GHK-Cu's gene expression profile against other peptides known to influence transcription. Each column summarizes the peptide's primary genetic targets, transcriptional mechanism, and clinical application.
  • GHK-Cu
  • COL1A1, COL3A1, DCN, VEGF, SOD1, MMP suppression
  • Copper-dependent nuclear trafficking and transcription factor activation
  • 1–10 µM
  • Wound healing, skin regeneration, anti-aging
  • Broadest gene modulation profile; requires copper binding for activity
  • BPC-157
  • VEGF, FGF, HIF-1α, eNOS
  • VEGF receptor signaling and angiogenic pathway activation
  • 200–500 µg/kg (in vivo)
  • Tendon repair, gastric ulcer healing, joint recovery
  • Strong angiogenic focus; minimal collagen or MMP modulation
  • TB-500 (Thymosin Beta-4)
  • Actin polymerization genes, integrin signaling
  • G-actin sequestration and cell migration promotion
  • 2–10 mg/week (in vivo)
  • Muscle injury, cardiac repair, corneal healing
  • Cell migration specialist; indirect collagen effects via fibroblast recruitment
  • Epitalon
  • Telomerase (TERT), melatonin synthesis (AANAT)
  • Pineal gland regulation and telomere maintenance
  • 5–10 mg/cycle (in vivo)
  • Circadian rhythm restoration, anti-aging
  • Targets aging pathways; no direct ECM or wound healing gene effects
  • Matrixyl (Palmitoyl Pentapeptide)
  • COL1A1, fibronectin, elastin
  • TGF-β receptor activation and downstream Smad signaling
  • 3–8% topical formulations
  • Cosmetic anti-aging, wrinkle reduction
  • Collagen-specific; lacks MMP suppression and antioxidant upregulation
