GHK-Cu 500mg Topical is a mid-size copper peptide powder from Peptide Sciences for cosmetic formulation and skin research.
Formulating with GHK-Cu
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide first identified in human plasma, where its levels decline with age. Formulation researchers study how pH, chelators and other actives affect its stability, as copper complexes can be sensitive to strong acids and certain ingredients such as vitamin C.

Research Considerations
Stability programmes with GHK-Cu commonly track colour change and peptide content by HPLC, as degradation of the copper complex is often visible as a shift from blue to green tones.
Quality Control, COA and Shipping
Consistency between lots is checked by HPLC and mass spectrometry, so researchers can compare results across experiments with confidence. Each order ships with a lot-specific Certificate of Analysis and cold-chain packaging.
