A COA showing 99% HPLC purity and 80% peptide content means the sample is very pure (99% of detected material is AHK-Cu), but only 80% of the sample weight is actually active peptide base (the other 20% is water, TFA salt, and other non-peptide components)
The charge transfer from BSA/AuNCs to FA-rGO weakens the AuS bond between cysteine residues and the Au core, which in turn reduces charge transfer from BSA ligands to AuNCs, leading to the fluorescence quenching of AuNCs
GHK-Cu represents a fundamentally different approach to hair restoration
