What are the potential side effects of BPC 157?

Potential risks of BPC-157 include possible acceleration of tumor growth and uncertain safety, since rigorous human evidence is sparse. 1 2

• BPC-157 may promote angiogenesis by increasing VEGF, potentially increasing blood flow to tumors. 3
• It may increase growth hormone receptors around injury sites, which could potentially accelerate growth of an existing tumor in that area. 4
• Animal research suggests a high lethal-dose safety margin, but that does not establish safety in people; the typical experimental dosing described was 300–500 micrograms subcutaneously two or three times weekly for about eight weeks. 5 Human evidence remains limited, and the discussion emphasizes the lack of rigorous clinical studies. 2
