hgh and ghk cu GHK-Cu: The Skin, Hair, Healthy Aging Peptide GHK-Cu is a naturally occurring peptide first discovered in human plasma and later identified in saliva and urine. It binds with copper ions to GHK-Cu (Copper Tripeptide) - Skin

However, we do know that some reproductive hormones, such as estrogen and progesterone, decline, and that follicle stimulating hormone (FSH) increases, as shown in the graph and described in the text below

The peptide does not appear to engage the canonical growth hormone receptor at concentrations relevant to its lipolytic effect, and its precise molecular target remains an area of active investigation

A structured titration schedule introduces the peptides gradually, allowing your body to adapt and giving you data about how you respond at each level

Because it's a fairly large and complex peptide, its particularly sensitive to handling
