What is GHK-Cu?
GHK-Cu is a small, copper-binding peptide with one of the longest research histories of any cosmetic and tissue-study compound. Here is what it is, where it came from, and what to check before you order.
A naturally occurring tripeptide
GHK is a tripeptide — just three amino acids — that binds copper ions with high affinity, forming the GHK-Cu complex. It was first identified in human plasma in the 1970s and was observed to decline with age, which sparked decades of follow-up research.
Because of its small size and copper-binding behavior, it became one of the most studied peptides in skin, wound, and tissue research models.
Its research history
GHK-Cu has appeared in studies on skin remodeling, collagen-related pathways, and tissue repair processes since the 1980s, and copper peptides found their way into cosmetic formulation research well before the current wave of interest in research peptides.
As with any research material, published findings come from controlled laboratory models — they describe what the molecule did in the study, not a promise about outcomes elsewhere.
What to verify before ordering
The GHK-Cu market is crowded with under-tested material. Common issues include low actual purity, copper content that does not match the claimed complex, and degradation from poor storage. A current, third-party certificate of analysis answers all three.
Novera Wellness GHK-Cu is independently tested to 99% purity, with batch documentation available before you order and bacteriostatic water included in every vial.
Novera Wellness supplies GHK-Cu for laboratory research use only. Request the current batch certificate before ordering — any serious supplier will provide it.
