- Subcutaneous injection (local, near injury site)
- 250–500 mcg daily
- Direct tissue penetration, localized VEGF upregulation, peak concentration within 2–4 hours
- Requires sterile technique, injection site rotation, and precise anatomical targeting
- Most commonly used in athletes targeting specific tendon or ligament injuries. Allows highest local concentration at injury site
- Subcutaneous injection (systemic, abdominal)
- Systemic distribution via lymphatic and circulatory routes, broader tissue exposure
- Easier administration than local injection, less precise targeting
- Preferred for multiple injury sites or generalized recovery support across high training volume
- Oral capsule
- 500–1000 mcg daily
- Gastric stability due to peptide origin, absorption via intestinal mucosa, lower bioavailability than injection
- No injection required, convenient for daily use, dose must be higher to compensate for first-pass metabolism
- Evidence for oral efficacy exists in gastric protection studies but is weaker for musculoskeletal applications. Higher doses required
- Nasal spray
- 200–400 mcg daily
- Absorption via nasal mucosa, bypasses first-pass metabolism, rapid systemic delivery
- Non-invasive, quick administration, may cause nasal irritation in some users
- Emerging option with theoretical bioavailability advantages but limited data in athletic populations
- Subcutaneous injection near the injury site remains the most evidence-supported route for targeted soft tissue repair. The local concentration achieved through peri-injury administration allows direct interaction with damaged fibroblasts and endothelial cells. Oral administration shows promise for gastric protection and systemic anti-inflammatory effects but lacks robust data for tendon healing specifically.
