Mechanism of Action Comparison
How GHK-Cu Works
GHK-Cu GHK-Cu is a naturally occurring copper peptide studied for stimulating collagen production, accelerating wound healing, and reversing visible signs of skin aging.
Copper delivery for collagen/elastin synthesis. Activates tissue remodeling, attracts immune cells to injury sites. Levels decline significantly with age.
How KPV Works
KPV KPV is a tripeptide fragment of alpha-MSH studied for powerfully reducing gut inflammation, investigated as a potential treatment for inflammatory bowel disease and wound healing.
Alpha-MSH fragment that potently suppresses NF-κB inflammatory signaling. Reduces pro-inflammatory cytokines and promotes mucosal healing.
Key Mechanistic Difference
GHK-Cu operates as a copper peptide, while KPV functions as a anti-inflammatory — these are fundamentally different pharmacological approaches.
