Best Peptides for Quad Strain: Mechanism Comparison
BPC-157 VEGF upregulation, FAK-paxillin pathway activation All phases (acute through remodelling) 250–500 mcg SC twice daily Moderate (animal models, limited human trials) Strongest evidence for angiogenesis and collagen organisation. First-line choice TB-500

- BPC-157
- VEGF upregulation, FAK-paxillin pathway activation
- All phases (acute through remodelling)
- 250–500 mcg SC twice daily
- Moderate (animal models, limited human trials)
- Strongest evidence for angiogenesis and collagen organisation. First-line choice
- TB-500
- Actin sequestering, MMP-9 downregulation
- Proliferative and remodelling (day 5+)
- 2–5 mg SC twice weekly
- Moderate (animal models, anecdotal human data)
- Best for preventing rigid scar tissue formation. Combine with BPC-157
- GHK-Cu
- TGF-beta activation, collagen synthesis
- Remodelling phase only
- 1–2 mg SC daily
- Low (dermal wound data only)
- Theoretical benefit but limited muscle-specific evidence
- IGF-1 LR3
- Satellite cell activation, muscle hypertrophy
- Remodelling phase (week 3+)
- 40–80 mcg SC daily
- Low to moderate (bodybuilding anecdotes, minimal clinical trials)
- Risk of fibrosis if used too early. Reserve for late remodelling
