GHK-Cu (Oral) vs KPV
An educational, source-based comparison of GHK-Cu (Oral) and KPV — how each peptide works, what it's researched for, and what to know before going deeper.
An oral formulation of the GHK-Cu tripeptide designed for systemic absorption. Research suggests the same copper-complex gene-modulating activity as topical forms, potentially supporting systemic tissue repair, immune modulation, and antioxidant capacity.
- Systemic tissue repair and regeneration
- Immune modulation and inflammation
- Lung and gut tissue health
- Age-related gene expression restoration
- • Oral bioavailability is lower than injectable; optimal dosing unclear.
- • Not FDA-approved for therapeutic use.
The C-terminal tripeptide (Lys-Pro-Val) of α-MSH. Research suggests anti-inflammatory effects via melanocortin pathways and intracellular NF-κB modulation — without the pigmentation effects of full-length α-MSH.
- Inflammatory bowel disease models
- Atopic dermatitis (topical research)
- Mast cell stabilization
- • Not FDA-approved.
- • Most evidence is preclinical.
