Protocol notes
Topical formulation chemistry matters more than peptide identity alone — vehicle viscosity, pH, and copper-redox interactions all influence outcomes. Run each peptide individually and as a combination, with a vehicle-only control on every animal.
Mechanistic rationale
GHK-Cu drives collagen, elastin, and antioxidant gene expression in fibroblasts. BPC-157 contributes angiogenic and anti-inflammatory effects, particularly in vascular wound beds. LL-37 contributes direct antimicrobial activity and host re-epithelialisation signalling — useful in contaminated or chronic wound models.
Endpoint suggestions
Wound-closure rate, re-epithelialisation, microvessel density, hydroxyproline content, and tensile strength of healed tissue are the principal endpoints.
Confounders
Combining GHK-Cu with reducing agents (vitamin C, sulfites) in a single vehicle can disrupt the Cu(II) complex. LL-37 binds plasma proteins and can adsorb to plastic — use low-binding labware.
