topical ghk cu vs injectable GHK-Cu Injectable: Which Route to Choose Topical peptides or injectable peptides:

Therefore, we suggest that SHH mediates a novel molecular mechanism for cyclosporin A-induced gingival complications [65]

ShimomuraT.et al.1997Hepatocyte growth factor activator inhibitor, a novel Kunitz-type serine protease inhibitor, 87

They work through entirely different mechanisms than copper peptides

From experimental data of kinetic measurements of BRET, following vehicle and baseline corrections, quantification of induced responses from individual peptide concentrations was determined by calculating the net area under curve from the 10 min response (AUC 0-10min) ) in GraphPad Prism version 9.0.1 (GraphPad Software Inc., San Diego, CA)
