- BPC-157
- VEGF upregulation, collagen synthesis
- 250–500 mcg/day SC near injury site
- 30–40% faster return to pain-free ROM
- Most versatile. Works across tendon, ligament, and muscle injuries with minimal systemic effects
- TB-500
- Actin modulation, fibroblast migration, anti-fibrotic
- 2–2.5 mg 2×/week (loading), then 2 mg 1×/week
- 25–35% reduction in scar tissue formation
- Best for preventing chronic stiffness and adhesions. Especially valuable in re-injury scenarios
- IGF-1 LR3
- Satellite cell activation, mTOR signaling, myofiber hypertrophy
- 40–80 mcg/day SC, post-training or pre-sleep
- 20–30% increase in regained muscle cross-sectional area
- Requires concurrent resistance training to be effective. Not a passive healing agent
- Before selecting a peptide, assess the injury type. BPC-157 excels in myotendinous junction tears where tendon reattachment to muscle is the limiting factor. TB-500 is the best peptide for muscle tear cases with visible hematoma or extensive bruising. Its anti-fibrotic effect prevents the rigid scar tissue that causes chronic range-of-motion loss. IGF-1 LR3 should be reserved for the late proliferative phase (weeks 3–6) when new muscle fibers are forming but haven't yet hypertrophied to pre-injury size.
