GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper-chelating tripeptide first isolated from human plasma by Loren Pickart in 1973. Plasma concentrations are approximately 200 ng/mL at age 20 and decline to approximately 80 ng/mL by age 60 — a 60% reduction documented in Pickart's own published research (Pickart L, Margolina A. Int J Mol Sci. 2018. PMID: 29986520). This age-correlated decline parallels measurable reductions in tissue repair capacity.
Collagen and Extracellular Matrix
At concentrations as low as 1–10 nanomolar, GHK-Cu stimulates both synthesis and breakdown of collagen and glycosaminoglycans in human fibroblast cultures — a balanced remodeling effect, not unconstrained accumulation. It also stimulates dermatan sulfate, chondroitin sulfate, and the proteoglycan decorin, while modulating matrix metalloproteinases and their inhibitors TIMP-1 and TIMP-2.

Wound Healing and Angiogenesis
In vivo studies across rabbits, rats, mice, and pigs document that GHK-Cu accelerates wound healing, increases blood vessel formation, and elevates antioxidant enzyme levels. Clinical data show GHK-Cu efficacy in diabetic ulcers and post-surgical wound recovery. A study at Stanford (Arch Facial Plast Surg. 2005;7(1):27–31, Pollard JD, Quan S, Kang T, Koch RJ, PMID: 15655171) found GHK-Cu stimulated bFGF and VEGF production in irradiated fibroblasts, with treated irradiated cells approaching the population-doubling time of normal unirradiated controls.
Gene Expression Modulation
A 2018 review (Pickart L, Margolina A, Int J Mol Sci, PMID: 29986520) documented GHK-Cu's influence on over 4,000 human genes at nanomolar concentrations — upregulating tissue repair genes and downregulating inflammation and fibrosis genes. This breadth of effect is unusual for a tripeptide.
