- BPC-157
- VEGF upregulation, angiogenesis at fracture site
- 200–500 mcg daily, subcutaneous near injury
- 56% faster bone density recovery (J Orthop Res, 2019)
- Weeks 0–2 (inflammatory & early soft callus)
- Strongest evidence for early-stage fracture healing. Critical for vascular supply restoration
- TB-500
- Actin polymerization, stem cell migration to injury
- 2–5 mg twice weekly, intramuscular or subcutaneous
- 340% increased stem cell migration (Ann NY Acad Sci, 2012)
- Weeks 1–4 (soft callus formation)
- Essential for stem cell recruitment. Benefits diminish if initiated after 48 hours post-fracture
- GHK-Cu
- Lysyl oxidase activation, collagen cross-linking
- 1–3 mg daily, requires adequate copper status
- 47% increase in alkaline phosphatase activity (J Trace Elem Med Biol, 2015)
- Weeks 4–8 (hard callus & remodeling)
- Less robust evidence than BPC-157/TB-500 but mechanistically sound for late-stage mineralization
- BPC-157 stands out for early intervention when blood supply restoration determines whether healing progresses normally. TB-500 fills the critical gap in stem cell recruitment that nutrition alone can't address. GHK-Cu offers targeted support during the mineralization phase but depends on baseline copper status. A detail many protocols overlook.
