Other Research Peptides It helps to see where the GHK copper peptide fits next to other commonly studied research compounds, since labs run comparative work across multiple peptides

The Bottom Line GHK-Cu is one of the most scientifically researched peptides, with a genuinely fascinating profile of biological activity and a natural presence in the human body

At nanomolar concentrations (1 to 10 nM), it stimulates collagen, glycosaminoglycan, and proteoglycan synthesis in dermal fibroblasts

It was first isolated from human plasma, where it naturally occurs at concentrations of around 200 ng/mL at age 20, declining to approximately 80 ng/mL by age 60
