GHK-Cu is a copper peptide that your body actually produces naturally — it is found in your blood, saliva, and other fluids. Copper might not be the first thing you think of for skin health, but it turns out it is essential for collagen production and wound repair. GHK-Cu acts like a delivery vehicle, carrying copper directly to the cells that need it most. It is one of the most widely used peptides in skincare products, and it also has systemic benefits when used by injection.
GHK-Cu works like a smart delivery system for copper. It picks up copper ions in the bloodstream and drops them off at cells that need copper to run their repair enzymes. This triggers a chain reaction: genes involved in healing switch on, collagen production ramps up, and the body's natural tissue-remodeling process gets more precise and efficient. It also helps regulate enzymes that break down old or damaged tissue, so the right amount is cleared away without overdoing it.
Typical Dose
1–2 mg per day
Dose Range
0.5–3 mg/day
Frequency
Once daily
Route
Topical (most common), subcutaneous injection, or oral
