How does GHK-Cu work?

Tissue remodeling, collagen, antioxidant.

The source catalog maps this mechanism to Skin, Hair. A biological mechanism describes how a compound interacts with the body; it does not by itself prove a clinical benefit.

What does the evidence tell us?

The source catalog rates the evidence as limited. Laboratory and animal findings cannot establish benefits or safety in people. Small or early studies may raise useful research questions without supporting routine clinical use.

Use the Citations tab to examine the underlying sources. Look for human studies, a relevant comparison group, meaningful outcomes, and adequate follow-up. An ingredient, approved drug, and compounded preparation may have different evidence.

Safety and considerations

For an unapproved use or compound, safety and effectiveness may be uncertain. Products sold for research are not a substitute for prescribed care. Do not infer a human dose, injection protocol, or treatment recommendation from preclinical research.

This library is educational and does not provide dosing or treatment instructions. A listing here does not indicate that Peppy offers the compound.
