- BPC-157
- VEGF upregulation, FAK-paxillin signaling in osteoblasts
- 40–60% faster callus formation in rat stress fracture models (Journal of Physiology and Pharmacology, 2018)
- 5–20 mcg/kg daily
- Subcutaneous (local) or intraperitoneal
- Best-documented peptide for stress fracture research. Mechanism directly targets bone remodeling phase
- TB-500 (Thymosin Beta-4)
- Actin sequestration, cell migration promotion
- Limited skeletal data. Primary evidence in soft tissue repair
- 5–10 mg/kg twice weekly
- Subcutaneous or intramuscular
- Promotes angiogenesis but lacks specific osteoblast activation. Secondary choice for bone injuries
- GHK-Cu (Copper Peptide)
- Collagen synthesis, metalloproteinase modulation
- Increases type I collagen but no fracture-specific studies
- 1–3 mg/kg daily
- Topical or subcutaneous
- Supports general wound healing. Insufficient data for stress fracture protocols
- Ipamorelin
- Growth hormone secretagogue
- Indirect bone density effects via GH/IGF-1 axis. No acute fracture data
- 200–300 mcg daily
- Subcutaneous
- Useful for long-term bone density research but not acute fracture healing
