Full research summary5 citations

GHK-Cu is a copper-binding tripeptide the body produces on its own, and it activates more than 4,000 repair genes, including the ones behind collagen and elastin synthesis. Plasma levels fall about 90% between age 20 and 60, which is exactly why aging-skin and connective-tissue research keeps circling back to it.

Storage & handling

Freeze-dried at -4°F; reconstituted at 36-46°F protected from light in an amber vial or foil wrap, and used sooner rather than later since copper oxidizes with no visible color change.

Research cautions

Ruled out entirely in Wilson's disease, copper dysregulation, or copper allergy, and extended continuous exposure can accumulate copper.
