GHK-Cu (Glycyl-L-Histidyl-L-Lysine, copper complex) is a naturally occurring copper-binding tripeptide identified in human plasma, where its concentration is observed to decline with age in research literature. It is one of the most extensively published peptides in dermal and wound-healing research, studied for its role in collagen remodeling and tissue-repair signaling.

Each vial is lyophilized and shipped with a batch-specific Certificate of Analysis confirming purity via HPLC and mass spectrometry.
