- TB-500
- Actin sequestration → enhanced cell migration
- High. Promotes endothelial cell chemotaxis and capillary formation
- Moderate. Downregulates MMPs, allowing organized collagen deposition
- 2–2.5mg subcutaneous twice weekly for 4–6 weeks
- Best for periosteal injuries requiring vascular regeneration and directional tissue remodeling
- BPC-157
- Vascular endothelial growth factor (VEGF) upregulation
- High. Increases VEGF expression and capillary density
- High. Directly stimulates fibroblast proliferation and tendon-to-bone healing
- 250–500mcg subcutaneous daily for 4–8 weeks
- Superior for tendon and ligament injuries; less tissue-specific than TB-500
- GHK-Cu
- Copper peptide → extracellular matrix remodeling and inflammation modulation
- Moderate. Indirect angiogenesis via reduced oxidative stress
- High. Stimulates decorin and glycosaminoglycan synthesis
- 1–2mg subcutaneous 3x weekly or topical application
- Effective for skin and superficial soft tissue; limited penetration to periosteum
- Ipamorelin + CJC-1295
- Growth hormone secretagogue → systemic IGF-1 elevation
- Low. Indirect angiogenesis through IGF-1-mediated pathways
- Moderate. Systemic collagen synthesis but not injury-targeted
- 200–300mcg ipamorelin + 100–200mcg CJC-1295 nightly for 8–12 weeks
- Broad regenerative effects but slower and less specific than injury-targeted peptides like TB-500
