GHK-Cu Explained: The Science Behind Copper Peptides, Healing, and Hair Regrowth

GHK-Cu (copper peptide) has surged in popularity across regenerative medicine, aesthetics, and biohacking—but what does the science actually say? In this episode of Decoding Health, Dr. Urban breaks down the real physiology behind GHK-Cu, a naturally occurring copper-binding tripeptide composed of glycine, histidine, and lysine. You’ll learn how this peptide supports wound healing, collagen remodeling, tissue regeneration, and why it’s increasingly used for skin rejuvenation and hair regrowth.

The conversation explores how GHK-Cu stabilizes and transports bioavailable copper, its role in activating matrix metalloproteinases (MMPs), and what preclinical research shows about systemic healing effects. Dr. Urban also addresses critical safety considerations, FDA status, compounding pharmacy regulations, injectable vs topical use, and why oral versions are largely ineffective. This episode offers a grounded, science-first look at one of today’s most talked-about peptides—without hype, shortcuts, or misinformation.
