Copper content: A comprehensive CoA for GHK-Cu should include copper quantification, typically by inductively coupled plasma mass spectrometry (ICP-MS) or a comparable method
Therefore, delivery efficiency and formulation design play a critical role in optimizing results
Neglecting sun protection Copper peptides provide zero UV protection
A specific caution for copper peptides: heat, shaking and incompatible diluents can drive copper to dissociate from the peptide, and loosely bound Cu can generate reactive oxygen species another reason to keep handling gentle and cold [2]
