Does BPC-157 cause cancer? Many say so, let's examine the evidence: 1) No human trials exist All cancer-related concerns come from in vitro (cell culture) studies, which are poor predictors of real-world outcomes. There is no study in animals or humans showing BPC-157 causes cancer growth. 2) The angiogenesis concern BPC-157 promotes blood vessel growth (angiogenesis), which theoretically could feed tumors. This same mechanism is why it heals tissue. No causal link to tumor growth has been demonstrated in vivo. 3) Rat studies show the opposite Multiple rodent studies actually show BPC-157 has anti-tumor effects, reducing certain cancer markers rather than promoting them. 4) Mechanism ≠ outcome Just because something influences a pathway associated with cancer doesn't mean it causes cancer. Aspirin affects COX-2. Sunlight affects DNA. Context matters. Overall... The concern is biologically plausible but empirically unsupported. That doesn't mean it's safe – it means we don't know. Would I recommend BPC? No. Have I seen it change dozens of lives? Yes. Have I seen it ever cause cancer? No. Would I take it if I had tumor growth? Certainly not. We need demand better research, not viral fear.
