BPC-157 is a peptide – essentially, a short chain of 15 amino acids (amino acids make up proteins). In this specific sequence of peptides, it is derived from a protein found naturally in the body in the gastric juices and it is believed to help repair the lining of the stomach and intestines in its natural state. Synthesized for supplement purposes, it has been shown in numerous animal studies across decades to have many positive benefits, above and beyond stomach repair. Some of the systems and ways in which BPC-157 works that have been validated by animal studies include: Speeds and aids the repair of soft tissues in the body. Protects and repairs damage caused to the gut, liver, and other systems by NSAIDs and other medications. Improves serotonin transport and synthesis, which has been implicated in many psychological conditions such as depression, anxiety, and similar. Improves blood pressure and protects heart function from a myriad of problems. Can help reduce allergic responses to natural triggers as well as some anti-viral properties on certain viruses that have been studied. Shown to improve IBS and other bowel problems, likely through the same gut repair mechanism. Several other less-well-studies benefits to everything from neurotransmitters to brain activity to oral health and even treating urinary incontinence.
