I encourage patients to approach claims about BPC-157 with informed optimism, recognizing the real promise while understanding the very real limitations of our current knowledge
Its worth noting that adverse effects are not common with high supplemental vitamin B12 intake, however, there is also no strong evidence to show that it has benefits in people who are not already deficient (largely due to the fact that your body only stores as much B12 as it needs and any excess will be excreted through your urine)
Reported side effects are rare and typically mild: mild redness or irritation at the application site (usually resolves with continued use or concentration adjustment), occasional skin tingling at higher concentrations (typically benign), and temporary dryness during initial use
It is primarily studied in cell culture and animal models and is not an approved human therapeutic
When applied to areas of injury, BPC-157 helps activate fibroblasts, the cells responsible for collagen production
