  • The following table summarizes the compounds researchers most commonly work with in dermatological studies, spanning both individual peptides and multi-peptide blends:
  • GHK-Cu
  • ~4,000-gene modulation, collagen synthesis, ECM remodeling, antioxidant
  • Topical serum or subcutaneous
  • Broadest dermatological research — aging, repair, gene expression
  • Matrixyl
  • Collagen fragment mimic → compensatory collagen synthesis
  • Topical formulation
  • Wrinkle-focused collagen studies
  • BPC-157
  • Angiogenic signaling, tissue repair, anti-inflammatory
  • Subcutaneous
  • Wound repair and tissue healing research
  • GLOW Blend
  • Combined BPC-157 + GHK-Cu + TB-500
  • Multi-pathway skin repair research ($69.99)
  • KLOW Blend
  • GLOW + KPV (adds anti-inflammatory α-MSH pathway)
  • Combined repair + anti-inflammatory research ($89.99)
  • TB-500
  • Actin regulation, cell migration, angiogenesis
  • Systemic tissue repair research including skin
  • The Matrixyl vs GHK-Cu comparison covers the two most-studied dermatological peptides head-to-head. The GLOW vs KLOW comparison covers the multi-peptide blends specifically.
