- BPC-157
- VEGF-mediated angiogenesis, collagen organization at injury site
- 200–400 mcg daily (human equivalent dose from animal models)
- Local subcutaneous or intramuscular near injury
- 30–40% reduction in healing time in animal tendon models
- Best for vascular repair and early-stage tissue regeneration. Must be injected near injury site
- TB-500
- Actin-binding cell migration, organized collagen deposition, reduced fibrosis
- 2–2.5 mg twice weekly for 4–6 weeks
- Systemic subcutaneous (abdominal region standard)
- Promotes functional tissue architecture vs scar tissue formation
- Best for structural integrity and long-term remodeling. Systemic action reaches injury regardless of injection site
- IGF-1 LR3
- Satellite cell activation, myogenic differentiation, muscle fiber regeneration
- 20–100 mcg daily during recovery phase
- Subcutaneous, timed post-injury or post-activity
- Accelerates muscle fiber regeneration in tears involving muscle belly
- Best for muscle fiber regeneration. Requires timing with satellite cell activation windows
