- KLOW
- MC1R activation → NF-κB inhibition → cytokine suppression
- Inflammation resolution, fibrosis prevention, scar quality studies
- 4–6 hours (topical/SC)
- Targets inflammatory phase without suppressing proliferation; copper-independent
- Cleanest mechanistic isolation for cytokine-focused protocols
- GHK-CU
- MMP upregulation, copper-dependent collagen synthesis modulation
- Matrix remodeling, photoaging models, general wound closure
- 8–12 hours
- Dual metalloproteinase and growth factor activity; requires copper ion coordination
- Broad-spectrum regenerative tool but introduces oxidative stress variables
- TB-500 (Thymosin Beta-4)
- Actin sequestration, cell migration, angiogenesis promotion
- Acute wound closure, re-epithelialization, vascular density studies
- 12–18 hours
- Strongest migration and angiogenesis signal among listed peptides
- First choice for diabetic ulcer or ischemic wound models
- KPV
- MC1R/MC3R/MC4R activation, systemic anti-inflammatory signaling
- Inflammatory skin conditions, systemic immune modulation research
- 6–9 hours
- Broader receptor profile than KLOW; systemic effects beyond dermal tissue
- Better for full-body inflammation models; less dermal specificity
- BPC-157
- VEGF pathway, nitric oxide modulation, angiogenesis
- Tendon/ligament repair, vascular-focused wound healing
- 24+ hours
- Strongest angiogenic signal; minimal direct anti-inflammatory activity
- Use when perfusion or vascular density is the dependent variable
