GHK-Cu sits in a different research area from the metabolic peptides — it is studied in the context of skin quality and regenerative science. This guide covers what it is and what the long research record describes.
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) first isolated from human plasma in 1973. It is one of the most studied peptides in cosmetic and regenerative research.
Because it was characterized so long ago, GHK-Cu has an unusually deep research record spanning roughly 50 years. It has been explored in the scientific literature in the context of skin quality, collagen signaling, and the visible characteristics of aging.
Unlike the incretin peptides, GHK-Cu is not studied for metabolic pathways. It belongs to regenerative and skin-science research — a useful reminder that 'peptide' is a broad category covering very different molecules and research questions.
