While GHK-Cu, a peptide that our bodies make, is used topically in skin cream in an attempt to reduce fine lines, it is not considered safe to inject due the lack of scientific research and the risks of triggering a potentially dangerous immune response
You do not need to inject directly into the injured tendon or muscle, and doing so increases discomfort without improving results
That dual role is part of why the research base touches so many systems: skin, hair follicles, wound beds, lung, gut, and bone in animal and cell models
