GHK vs GHK-Cu: peptide and copper complex
GHK vs GHK-Cu: peptide and copper complex: Compare identities, model types and limitations. These are research comparisons, not treatment rankings.
GHK
The free tripeptide is distinct from its copper complex. The copper-complex studies below are not evidence about every free-peptide formulation.
GHK-Cu
A copper-binding tripeptide investigated in extracellular matrix and skin biology. GHK combines glycine, histidine, and lysine and can bind copper. Studies examine collagen-related processes and tissue remodelling. An experimental rat wound study reported increased extracellular-matrix accumulation. Topical cosmetic research addresses different formulations and exposure conditions from a laboratory reagent. Animal and topical findings do not establish injectable efficacy or safety. Copper sensitivity and copper-metabolism disorders matter. The 50 mg and 100 mg listings are different quantities, not different evidence levels.
Comparison limits
A shared category does not prove equal effects, compatibility or suitability. Verify the exact sequence, formulation and batch. Do not substitute a related molecule or ingredient finding for direct evidence.
