Summary GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper peptide with profound regenerative, anti-aging, and wound-healing properties
Right now, there is no solid, peer-reviewed research showing that oral peptide products (like those sold online) reliably reach the bloodstream or create the same healing effects seen with injectable peptides Though some peptides can be compounded for oral administration or given sublingually (under the tongue), there therapeutic impact is typically limited
Why It Works: Provides bioavailable glycine, proline, and hydroxyproline, the primary amino acids used to rebuild collagen in skin, tendon, ligament, and cartilage tissue Small collagen-derived peptide fragments (e.g
