ghk-cu plasma concentration age decline (glycyl-L-histidyl-L-lysine) is a naturally occurring copper-binding peptide found in human plasma. As levels with age, so may its support of the biological processes involved in collagen production, skin repair, and ghk-cu plasma levels age decline

It targets only one receptor (GLP-1) compared to tirzepatide dual and retatrutide triple

The molecules in a well-formulated serum (GHK-Cu, EGF analog, PDRN, and a multi-MW hyaluronic acid system) each contribute a distinct, evidence-backed effect
