GHK-Cu is a small, naturally occurring copper peptide (a tripeptide, meaning three amino acids: glycine, histidine, lysine) bound to a single copper ion
The peptide occurs naturally in human plasma, and exogenous supplementation essentially restores levels toward youthful ranges rather than introducing foreign compounds
Its antioxidant power promotes healthy aging, protects the skin, reduces hyperpigmentation, and improves general health
In equine diets, phosphorus is supplied naturally by forages, grains, and protein meals such as oats and soybean meal
