Flat Dosing Reference Chart The table below shows standard flat dose recommendations without weight adjustment, which represents how most practitioners approach GHK-CU
At the concentrations typically found in cosmetic products, systemic absorption through intact skin is considered minimal, and copper toxicity from topical use has not been reported in the published literature
A first-generation copper peptide that breaks down when combined with Vitamin C requires different handling than a second-generation version designed for better stability
However, for best results, we recommend using the full Hairgenetix routine: Copper Peptide Shampoo (cleanses and delivers GHK-Cu) Copper Peptide Conditioner (conditions and delivers additional GHK-Cu) Copper Peptide Serum (concentrated topical treatment) The combined approach ensures copper peptides are delivered at multiple points during your routine, maximising scalp exposure time
Expression and purification of recombinant ghk tripeptides are able to protect against acute cardiotoxicity from exposure to waterborne-copper in zebrafish
