This comparison does not assign a generated winner or score.
- TB-500 (Thymosin Beta-4)
- Upregulates actin polymerisation; promotes angiogenesis and fibroblast migration
- 5–10mg per injection
- Twice weekly (loading phase), then weekly (maintenance)
- Preclinical animal studies; equine tendon data; anecdotal athlete reports
- Most plausible mechanism for periosteal repair due to vascularisation effects. But no human RCTs
- BPC-157
- Modulates nitric oxide and VEGF pathways; promotes localised angiogenesis
- 250–500mcg per injection
- Daily (subcutaneous or near injury site)
- Preclinical rodent studies; no human trials for orthopaedic injuries
- Effective for gut and soft tissue in animal models; weaker evidence for bone-related injuries
- GHK-Cu (Copper Peptide)
- Stimulates collagen synthesis; anti-inflammatory through TGF-beta modulation
- 1–3mg per injection
- 2–3 times weekly
- Mostly dermatological studies; minimal orthopaedic data
- Better suited for skin and superficial tissue. Insufficient evidence for deep periosteal injuries
- Ipamorelin (Growth Hormone Secretagogue)
- Stimulates pituitary GH release; indirect anabolic and recovery effects
- 200–300mcg per injection
- Once or twice daily
- General recovery data; no injury-specific studies
- Systemic recovery support, not injury-targeted. Too indirect for acute shin splint treatment
