A naturally occurring tripeptide locked inside your collagen that modulates 4,192 human genes, acts as a safe copper chaperone, and signals systemic repair, with plasma levels dropping 60% between ages 20 and 60.

GHK-Cu (Glycyl-L-Histidyl-L-Lysine) is a naturally occurring tripeptide embedded in Type I collagen. Liberated during tissue injury, it acts as a master repair signal modulating 4,192 human genes (roughly one-third of the genome). It drives collagen synthesis, delivers copper safely to enzymes like Superoxide Dismutase via a unique square-planar pyramid configuration, and shows emerging potential in gut barrier repair (SIRT1/STAT3) and COPD reversal (127-gene signature). Plasma levels decline 60% by age 60. Clinical protocols use a biphasic 30-day cycle (1mg escalating to 2mg) with a mandatory 30-day rest. FDA Category 2 restricts legal compounding for systemic use. Contraindicated in active malignancies and Wilson's Disease.
