GHK-Cu Osteoarthritis Mechanism: Peptide Comparison
GHK-Cu NF-κB inhibition, MMP suppression, lysyl oxidase activation 37–42% reduction in synovial fluid samples Increases COL1A1, COL3A1 mRNA 1.8–2.3× baseline Yes. Central to mechanism Most direct evidence for cartilage matrix support; dual cytokine and collage

- GHK-Cu
- NF-κB inhibition, MMP suppression, lysyl oxidase activation
- 37–42% reduction in synovial fluid samples
- Increases COL1A1, COL3A1 mRNA 1.8–2.3× baseline
- Yes. Central to mechanism
- Most direct evidence for cartilage matrix support; dual cytokine and collagen pathway engagement
- BPC-157
- Angiogenesis promotion, VEGF upregulation, tendon-ligament repair
- Limited data on OA-specific cytokine reduction
- Indirect. Supports vascular supply to repair sites
- No
- Strong evidence for soft tissue repair; less specific to cartilage degradation pathways
- TB-500 (Thymosin Beta-4)
- Actin sequestration, cell migration, anti-inflammatory
- Reduces IL-1β, IL-6 indirectly via immune modulation
- Indirect. Promotes cell migration to injury sites
- Broad anti-inflammatory effects; lacks targeted collagen synthesis mechanism seen with GHK-Cu
- Epitalon
- Telomerase activation, cellular senescence delay
- No direct effect on inflammatory cytokines
- No direct collagen pathway modulation
- Longevity-focused; minimal relevance to acute OA pathology
