WHAT IS GHK-CU?

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide with just three amino acids bound to a copper ion. Your body already makes it. It circulates in your blood, saliva, and urine, and it plays a central role in tissue repair, collagen production, and wound healing.

It was first identified in human plasma in 1973 by Dr. Loren Pickart at the University of California, San Francisco. Pickart noticed that plasma from younger donors stimulated liver cells to produce proteins more effectively than plasma from older donors. He traced the effect to this small copper-binding peptide that launched five decades of research.

The problem is that your body produces less of it as you age. Plasma levels decline significantly: approximately 200 ng/ml at age 20, dropping to roughly 80 ng/ml by age 60. That is a 60% decline in the molecule responsible for stimulating collagen synthesis, coordinating tissue repair, and maintaining skin architecture.

GHK-Cu is one of the most extensively studied peptides in dermatology and wound healing, with over 70 published studies spanning half a century. It is not a new discovery or a speculative compound. It is a well-characterized molecule with a substantial research base.

GHK-Cu is not a synthetic drug. It is a molecule your body already produces. Therapeutic GHK-Cu simply restores levels that have declined with age.
