GHK-Cu

Why do people find it interesting?

GHK-Cu is studied for processes involved in skin repair, collagen, elastin and wound healing. Most established cosmetic use is topical; claims about injected GHK-Cu require more caution.

What might you notice?

Some studies and user reports describe changes in skin quality or hair appearance.

What happens in your body?

GHK-Cu works as a signal for repair: it helps bring repair cells to the area and activates genes involved in tissue rebuilding. It is linked with collagen and elastin production, antioxidant and anti-inflammatory processes, and activity in hair follicles.

Keep the context

Important to know

Possible short-term side effects include local sensitivity, redness, mild irritation or bruising at the injection site; most reports describe these as mild and temporary.

Dose information from the guide
