Prins, M

Understanding the Evidence Level: While laboratory (in-vitro) studies show GHK-Cu signals collagen production, human cosmetic trials largely show improvements in surface hydration and texture

The safety profiles differ as well

It is an anti-ulcer peptide (9-12), interacting with NO-system (13), and, unlike other peptides, it is particularly stable in gastric juice (14) and is used consistently without a carrier (9-11, 13-24), being safe in patients with the inflammatory bowel disease (coded PL-10, PLD 116, PL 14736) (21)

Source quality dramatically influences outcomes
