A short, sourced summary of where GHK-Cu appears in the published research record. For context only. Not a claim, not a protocol, not advice.

GHK-Cu is a copper-binding tripeptide composed of glycine, histidine, and lysine (Gly-His-Lys) complexed with a copper ion. The peptide was first isolated from human plasma in 1973 and has been studied extensively for its role in copper transport and tissue-related signaling pathways.

In published preclinical literature, GHK-Cu has been investigated across cell-culture and rodent models examining its interactions with fibroblast biology, extracellular matrix proteins, copper-dependent enzymes, and inflammatory signaling cascades. Plasma concentrations of GHK have been documented to decline with age in healthy human studies, which has driven academic interest in its biology.

The compound is most-cited in the literature alongside investigations of collagen and elastin synthesis, antioxidant pathways, and copper homeostasis. It has not been approved by the FDA for any therapeutic indication and remains classified as a research compound.

That blue tint is the chemistry working as expected. GHK-Cu is a copper-binding tripeptide — the GHK peptide chelates a Cu²⁺ ion, and that copper coordination is what gives the lyophilized powder its characteristic light blue color. A pure white GHK-Cu powder would actually be a red flag (it would suggest the copper is not bound or that the product is just GHK without copper). The Certificate of Analysis confirms the copper-bound form by mass spectrometry.
GHK is the bare tripeptide (Gly-His-Lys). GHK-Cu is the same tripeptide bound to a copper(II) ion — the active form most documented in the published research literature. The copper coordination is what enables interactions with the copper-dependent enzymes studied in the wound healing and ECM literature. Most peer-reviewed studies on this molecule reference the Cu-bound form. This product is GHK-Cu, not bare GHK.
