- BPC-157
- VEGF pathway activation, FAK upregulation, angiogenesis
- Vascular injury models, tendon repair, gastric ulcer studies
- 28 days at 2–8°C
- Does not replicate actin-binding; limited data on chronic dosing effects
- Best first-line alternative for vascular and soft tissue repair protocols
- GHK-Cu
- TGF-β signaling, collagen I/III synthesis, matrix remodeling
- Dermal wound healing, ligament repair, fibrosis studies
- 14 days at 2–8°C (copper oxidation risk)
- Slower onset than vascular peptides; requires copper ion stability
- Ideal for structural repair; combine with angiogenic peptides for synergistic effect
- GHRP-6
- Growth hormone secretagogue, IGF-1 elevation, satellite cell activation
- Muscle regeneration models, systemic recovery studies
- 30 days at 2–8°C
- Indirect mechanism; requires functional pituitary axis in model organism
- Effective for systemic growth factor support but not localized tissue repair
- Pentadecapeptide analogs
- Varies by sequence; some target nitric oxide pathways
- Inflammation modulation, endothelial function research
- Highly variable by analog
- Limited peer-reviewed validation for most commercial variants
- Use only with full sequence verification and published validation data
