What Is GHK-Cu?
Tripeptide structure, copper coordination chemistry, and the 60% age-related decline
Three Amino Acids, One Copper Ion
GHK-Cu is one of the smallest biologically active molecules in your body -- just glycine, histidine, and lysine wrapped around a single copper ion. Despite its simplicity, this tripeptide-copper complex has a binding affinity so high it can steal copper from albumin, the most abundant protein in your blood.
The Amino Acid Trio
Glycine, histidine, and lysine -- the three building blocks of GHK-Cu.
Copper Binding
How GHK captures and holds copper(II) ions.
Coordination Geometry
The square-planar arrangement that gives GHK-Cu its stability.
Natural Occurrence
Where GHK-Cu is found in the body and how it circulates.
The Age-Related Decline
Why GHK-Cu levels drop by 60% between age 20 and 80.
