GHK-Cu: The Copper Peptide Revolutionizing Skin and Tissue Repair
Reviewed by the TRIM FITT Clinical Team · Evidence-Based Medicine
GHK-Cu — glycyl-L-histidyl-L-lysine copper — is a naturally occurring copper peptide that has been studied for over four decades. First isolated from human plasma in the 1970s by Dr. Loren Pickart, GHK-Cu has since been shown to be one of the most powerful tissue-regenerating compounds found in the human body. Its concentration declines with age, falling from approximately 200 ng/mL in young adults to as low as 80 ng/mL by age 60 — a drop that correlates with reduced wound healing capacity and skin aging.
What the Research Shows
GHK-Cu has been the subject of hundreds of peer-reviewed studies. Research demonstrates its ability to stimulate collagen and elastin synthesis, activate antioxidant enzymes, promote angiogenesis, and modulate anti-inflammatory pathways. A comprehensive review in Biomolecules identified GHK-Cu as a regulator of over 4,000 human genes — influencing pathways related to inflammation, tissue remodeling, and even cancer suppression. Topically and systemically, GHK-Cu has shown consistent evidence for wound healing acceleration and skin quality improvement.
Bottom line: GHK-Cu is one of the most scientifically validated peptides for tissue repair and skin regeneration, with a uniquely broad mechanism of action at the genomic level.
