- BPC-157
- Upregulates VEGF and angiogenesis in hypoxic tissue; increases capillary density at injury site
- 200–500 mcg/day subcutaneous near injury site for 4–8 weeks
- Subcutaneous injection into thenar eminence or web space
- 3–4 weeks for reduced pain on resistance testing; 6–8 weeks for measurable tensile strength improvement
- Best for ligament injuries (UCL tears, collateral ligament sprains) where vascularization is the limiting factor in healing
- TB-500 (Thymosin Beta-4)
- Enhances actin-based cell migration; increases fibroblast recruitment and collagen alignment
- 2–2.5 mg twice weekly for weeks 1–3, then 2 mg weekly for weeks 4–8
- Subcutaneous injection (systemic. Not site-specific)
- 4–6 weeks for improved ROM without pain; 8–10 weeks for return to loaded activities
- Best for tendon injuries (extensor pollicis longus strains, flexor tendon damage) requiring organized collagen fiber remodeling
- GHK-Cu (Copper Peptide)
- Delivers bioavailable copper for lysyl oxidase activity; upregulates Type I collagen synthesis via TGF-beta activation
- 1–3 mg/day subcutaneous for 6–10 weeks
- Subcutaneous injection or topical (subcutaneous preferred for deep tissue)
- 5–7 weeks for improved grip strength; 10–12 weeks for full collagen maturation
- Best for chronic injuries or post-surgical recovery where collagen crosslinking and tensile strength are primary concerns
