Most biologically active peptides bind to well-characterized receptors that initiate defined signaling cascades

Copper Chelation and Delivery At the most fundamental level, GHK functions as a copper chelator and delivery system - the tripeptide binds Cu with exceptionally high affinity (binding constant approximately 10 M, among the highest known for biological copper chelators), forming a square planar coordination complex where the copper ion is coordinated by the nitrogen atoms of the terminal amino group, the two peptide bonds, and the imidazole nitrogen of histidine

Research suggests possible links to skin models, nerve repair, stem cell regulation, and gene expression pathways

The Lee Clinical Trial (2016) This is the study that matters most, because it was conducted on actual humans losing actual hair
