GHK-Cu
The beauty peptide — a copper peptide adored for skin, hair and a youthful glow.
What is it?
GHK-Cu is a natural copper-binding peptide the body makes on its own — but levels drop as we age. It has a huge following in skincare and beauty circles, where it is prized for supporting firmer-looking skin and healthier hair. It is one of the most beloved peptides for anyone focused on looks and ageing gracefully.

What is it used for?

How it works
GHK-Cu carries copper — a mineral tied to the skin's structural proteins such as collagen. This connection to collagen and repair signalling is why it is such a star ingredient in the beauty world.

Storage
- Avoid freeze–thaw cycles
Technique
- Clean the vial stopper and the skin with an alcohol swab and let both air-dry.
- Pinch a skinfold and insert the needle at 45–90° into the subcutaneous tissue.
- Do not aspirate for subcutaneous injections — inject slowly and steadily.
- Wait 5–10 seconds before withdrawing, then apply gentle pressure. Do not rub the site.
- Rotate sites systematically — abdomen (at least 5 cm from the navel), thighs and upper arms — to avoid lipohypertrophy.
- Use a new sterile 28–31 G insulin syringe every time and dispose of it in a sharps container.
Safety & evidence
- Published human GHK-Cu research has mostly looked at topical and wound-care formulations — subcutaneous schedules are a research-use convention.
- Follow the vial and batch documentation for temperature, moisture and light protection.
- Stability once prepared depends on concentration, pH, diluent, sterility, container and temperature.
